Duomo, Milan

Duomo, Milan

The Milan Cathedral, officially the Metropolitan Cathedral of the Nativity of the Blessed Virgin Mary, is the cathedral of the Archdiocese of Milan and an Italian national monument. Symbol of the Lombard capital, and located in the square of the same name in the center of the metropolis, it is dedicated to Santa Maria Nascente. It is the largest church in Italy (the largest in the Italian Republic, since the basilica of San Pietro, which is larger, is in fact in the territory of the Vatican City; it is the second largest considering the whole Italian peninsula), the third in the world by surface area, the sixth by volume. It is the seat of the parish of Santa Tecla in the cathedral of Milan.

 

History

In the place where the cathedral stands, there were once the ancient cathedral of Santa Maria Maggiore, the winter cathedral, and the basilica of Santa Tecla, the summer cathedral. After the collapse of the bell tower (1386), Archbishop Antonio de' Saluzzi, supported by the population, promoted the reconstruction of a new and larger cathedral (May 12, 1386), which would rise on the site of the oldest religious heart of the city. The construction of the cathedral was also dictated by very specific political choices: with the new construction site, the population of Milan intended to underline the centrality of Milan in the eyes of Gian Galeazzo who, with a coup d'état, had recently deposed his uncle Bernabò and reunified the Visconti domains, pre-eminence questioned by the choice of the new lord to reside and maintain his court, like his father Galeazzo II, in Pavia and not in Milan. For the new building, both previous churches began to be demolished: Santa Maria Maggiore was demolished first, Santa Tecla later, in 1461-1462 (partially rebuilt in 1489 and definitively demolished in 1548).

The new church, judging by the archaeological remains that have emerged from the excavations in the sacristy, must have originally foreseen a brick building according to the Lombard Gothic techniques. On 12 January 1387 the foundations of the pylons were laid, colossal works that had already been designed from a design the previous year. During 1387 the excavation of the foundations continued and the pylons continued. What was done before 1386 was almost completely undone. During the year the duke of Milan Gian Galeazzo Visconti assumed control of the works, imposing a more ambitious project. The material chosen for the new construction then became Candoglia marble (and to a much lesser extent also Ornavasso marble) and the architectural forms those of the late Gothic of Rhine-Bohemian inspiration. Indeed, Gian Galeazzo's desire was to give the city a grandiose building in step with the most up-to-date European trends, which symbolized the ambitions of his state, which, in his plans, should have become the center of an Italian national monarchy as it was success in France and England, thus inserting itself among the great powers of the continent. Gian Galeazzo made the quarries available and granted substantial subsidies and tax exemptions: each block destined for the Cathedral was marked AUF (Ad usum fabricae), and therefore exempt from any transit tax. As evidenced by the rich archive preserved to this day, the first chief engineer was Simone d'Orsenigo, flanked by other Lombard masters, who in 1388 began the perimeter walls. In 1389-1390 the Frenchman Nicolas de Bonaventure was commissioned to design the large windows.

French and German architects were called to direct the construction site, such as Jean Mignot, Jacques Coene or Enrico di Gmünd, who however remained in office for a very short time, encountering open hostility from the Lombard workers, accustomed to a different work practice. The factory then proceeded in a climate of tension, with numerous revisions, which in spite of everything gave rise to a work of unmistakable originality, both in the Italian and European panorama.

Initially the foundations had been prepared for a building with three naves, with square side chapels, whose dividing walls could also act as buttresses. It was then decided to do without the chapels, bringing the number of naves to five and on 19 July 1391 the enlargement of the four central pillars was approved. However there was a growing concern for the stability of the entire structure, due to insufficient inertial masses to oppose the action of the thrusts. So in September of the same year the Piacenza mathematician Gabriele Stornaloco was interrogated to define the cross section and the elevation, through a precise geometric and cosmological diagram (Stornaloco was also an astronomer and cosmographer). On May 1, 1392, the shape of the progressively decreasing naves was chosen for a maximum height of 76 arms.

However, relations between Gian Galeazzo and the top management of the factory (chosen by the citizens of Milan) were often tense: the lord (who had become duke of Milan in 1395) intended to transform the cathedral into the dynastic pantheon of the Visconti, inserting the funeral monument of his father Galeazzo II and this met with strong opposition from both the factory and the Milanese, who wanted to emphasize their autonomy. A clash arose, which forced Gian Galeazzo to decide the foundation of a new construction site destined exclusively for the Visconti dynasty: the Certosa di Pavia, to which, without scruple, he repeatedly assigned many employees of the Duomo factory, even of high level, such as Giacomo da Campione or Giovannino de' Grassi.

 

Construction of the basilica body

In 1393 the first capital of the pillars was sculpted, based on a design by Giovannino de' Grassi, who oversaw a new design for the large windows and was general engineer until his death in 1398. The presence of the capitals on the pillars clearly differentiates it from the Gothic d' beyond the Alps, where the ribs of the pillars continue in the arches giving greater vertical momentum to the construction. In 1400 he was replaced by Filippino degli Organi, who supervised the construction of the large apsidal windows. From 1407 to 1448 he was in charge of the construction, which completed the apse and the cross foot, temporarily closed by the recomposed facade of Santa Maria Maggiore.

On 16 October 1418 Pope Martin V consecrated the high altar, which was moved to its definitive position in the center of the new cruise between 11 and 12 October. Up to that moment the altar had in fact remained in its previous location in the old body of Santa Maria Maggiore, protected by the remains of the old apse, demolished only on this occasion. The ceremony was grandiose and had a huge popular participation, even if the figures proposed by the chronicles of the time (80,000 and 100,000 people) must be considered improbable, probably corresponding to the total population of the city at the time.

From 1452 to 1481 Giovanni Solari was in charge of the construction site, who for the first two years was also assisted by Filarete, a Tuscan architect called by Duke Francesco Sforza. Guiniforte Solari, Giovanni's son, and Giovanni Antonio Amadeo followed, who with Gian Giacomo Dolcebuono built the lantern in 1490. Upon Amadeo's death (1522) the successive masters made various "Gothic" proposals, including that of Vincenzo Seregni di flank the facade with two towers (about 1537), not built.

In 1567 the archbishop Carlo Borromeo imposed a diligent restart of the works, putting Pellegrino Tibaldi in charge of the factory, who redesigned the presbytery, which was solemnly reconsecrated in 1577, even if the church was not yet finished.

 

Façade

As for the facade, Pellegrino Tibaldi drew up a project in 1580, based on a two-story base enlivened by giant Corinthian columns and with an aedicule in correspondence with the central nave, flanked by obelisks. The death of Carlo Borromeo in 1584 meant the removal of his protégé who left the city, while the construction site was taken over by his rival Martino Bassi, who sent Gregory XIV, the Milanese pope, a new facade project.

In the 17th century, the supervision of the works saw the presence of the best city architects, such as Lelio Buzzi, Francesco Maria Richini (until 1638), Carlo Buzzi (until 1658) and the Quadrios. In the meantime, in 1628 the central portal had been completed and in 1638 the work on the façade continued, with the aim of creating an aedicule effect inspired by Santa Susanna in Rome. To this end, the drawings by Luigi Vanvitelli (1745) and Bernardo Antonio Vittone (1746) arrived in the 18th century.

Between 1765 and 1769 Francesco Croce completed the crowning of the lantern and the main spire, on which the gilded copper Madunina was raised five years later, destined to become the symbol of the city. The scheme of Buzzi's façade was taken up again at the end of the century by Luigi Cagnola, Carlo Felice Soave and Leopoldo Pollack. The latter began the construction of the balcony and the central window.

In 1805, at the direct request of Napoleon Bonaparte, Giuseppe Zanoia started the works for the completion of the facade, in anticipation of the Coronation of Napoleon King of Italy, which took place on 6 May 1805. The project was finally concluded in 1813 by Carlo Amati. The addition of statues and the erection of the spiers continued throughout the nineteenth century, by various architects (Pestagalli, Vandoni, Cesa Bianchi), inspired by the fifteenth-century spiers. Among the sculptors who worked there in the early 19th century, Luigi Acquisti can be mentioned.

 

Maintenance and restorations

In 1866 the low bell tower that was located on the nave was demolished and the bells were transferred to the tiburium, between the double vaults. Throughout the 19th century the spiers and architectural decorations were completed, until 1892. Restoration works also followed throughout the century, aimed at replacing the materials damaged by time.

During the Second World War, the Madonnina was covered in rags, to prevent the reflections of light on its recently redone gilded surface from being used as a reference point for Allied bombers flying over the city, while the windows were previously removed and replaced by rolls of cloth. Although it was not hit by high-potential bombs, the cathedral was also damaged during aerial bombardments and its central bronze door still shows some "wounds" from fragments of bombs that exploded nearby. After the Second World War, following the damage suffered by aerial bombardments, the Cathedral was largely restored, subsequently the remaining wooden doors were replaced with others in bronze, the work of the sculptors Arrigo Minerbi, Giannino Castiglioni and Luciano Minguzzi.

The four central pillars that support the tiburium were built in serizzo with only the external part in marble. The two parts, internal and external, were held together with lime and broken bricks. This lack of uniformity significantly diminished their ability to sustain. Furthermore, the lantern and the spire of the Madonnina were built on round arches, positioned above the pointed arches. These arches stressed the piers unevenly, pushing them outward. During the 19th century, fearing that they might collapse, there were numerous restoration interventions which, rather than solving the problems, concealed the signs. Towards the middle of the 20th century, due to the increase in traffic (with consequent continuous vibrations) and the lowering of the water table (which led the pylons to sink slightly), the static situation of the Cathedral became critical.

In 1969, to avoid collapses (pieces of marble, even of large dimensions, had already detached, falling into the aisles), the area surrounding the Cathedral was closed to traffic and the slowdown of trains on line 1 of the underground was ordered. The static restoration of the pylons began in 1981 and was completed in 1986 on the occasion of the six hundredth anniversary of the construction. Even today, the maintenance of the cathedral is entrusted to the Veneranda Fabbrica del Duomo di Milano, whose interventions are continuous, so as to give rise to the Milanese expression Longh as the factory of Domm, to mean something interminable.

Urban context

«The Duomo, symbol par excellence of Milan, is the first thing you look for when you get up in the morning and the last thing your gaze rests on in the evening. It is said that the Milan Cathedral comes only after St. Peter's in the Vatican. I cannot understand how it can be second to any other work done by the hand of man"
(Mark Twain)

In ancient times, the Cathedral was surrounded by the dense medieval urban fabric which, as around other large French and German cathedrals, created sudden and majestic views of the mammoth building, which looked like a marble mountain emerging from a network of minute brick buildings. The ancient aspect of the area is testified today by ancient views and a series of photographs from the mid-nineteenth century. With the opening of the square by Giuseppe Mengoni between 1865 and 1873, the facade of the Cathedral could become a grandiose scenographic background, but, as the numerous controversies did not fail to point out, banal.

The left side remains visible almost only foreshortened, due to the proximity of the surrounding buildings, while the entrance to via Vittorio Emanuele II allows you to observe the articulation of the volumes of the apse, the transept and the lantern, up to the main spire of the Madonna. Other interesting glimpses are visible from Piazza Fontana, from the glimpse of the Verziere, from the small square of the Royal Palace or from the terrace on the first floor of the Arengario.

 

Architecture

The style of the Cathedral, being the result of centuries-old works, does not respond to a precise movement, but rather follows an idea of mammoth and phantasmagorical "Gothic" gradually reinterpreted. Despite this, and despite the stylistic contradictions in the architecture, the Cathedral presents itself as a unitary organism. In fact, the gigantic stone machine fascinates and attracts the popular imagination, also by virtue of its ambiguity, made up of afterthoughts, discontinuities and, sometimes, makeshifts. Even the concept of Gothic "authenticity", when one thinks of how in reality most of the visible structures date back to the neo-Gothic period, not to mention the frequent replacements, is actually a distortion of the very essence of the monument, which should instead be seen as a architectural organism always in continuous and necessary reconstruction.

The cathedral has a Latin cross plan, with a cross-foot with five naves and a three-nave transept, with a deep presbytery surrounded by an ambulatory with a polygonal apse. At the intersection of the arms, the tiburium rises as usual. The whole has a notable vertical thrust, a transalpine rather than an Italian characteristic, but this is partly attenuated by the horizontal expansion of the space and by the slight difference in height between the naves, typical of Lombard Gothic.

The load-bearing structure is made up of pillars and perimeter walls reinforced by buttresses at the height of the pillars themselves. This is a feature that differentiates the Milanese cathedral from the transalpine cathedrals, limiting, with respect to traditional Gothic, the opening of the large windows (long and narrow) and giving the whole (with the exception of the apse) a predominantly "closed" form, where the wall is above all an element of strong demarcation, also underlined by the high plinth of the Lombard tradition. Thus the free upward momentum is lost. This is evident even if one considers that spiers and pinnacles have no load-bearing function, in fact they were added sporadically over the centuries, until the crowning was completed in the 19th century.

The buttresses have the shape of triangles and serve to contain the lateral thrusts of the arches. The base is in masonry, as are the internal parts of the walls and other elements, while a core of serizzo was used in the pillars; even the sails of the vaults are in brick. The exposed facing, which also has a load-bearing role, not only as a covering, is instead in pinkish white Candoglia marble with gray veins: the quarry, since the time of Gian Galeazzo Visconti, is still owned by the Fabbrica del Duomo.

The external walls are enlivened by a thick mass of polystyle semi-pillars which are crowned above, below the terraces, by an embroidery of polylobed arches surmounted by cusps. The pointed arch windows are rather narrow, since, as has been said, the walls have a load-bearing function.

The terraced roof (also in marble) is unique in Gothic architecture, and is supported by a double crossed order of minor vaults. In correspondence with the pillars there is a "forest" of pinnacles, connected to each other by flying buttresses. In this case the pinnacles have no structural function, in fact almost all date back to the first half of the 19th century. In the ancient drawings and in the large model of 1519 by Bernardo Zenale (Grande Museo del Duomo di Milano) we see a central crest which was to highlight even more the triangular shape, both along the nave and the transept, connecting to the lantern, and which was excluded from the project in 1836.

 

External architecture

The part completed first is the apse, pierced by large windows, where the coat of arms of Gian Galeazzo Visconti appears. The statues, buttresses, gargoyles and spiers generally date from the time of his successor, Filippo Maria Visconti, up to the 19th century. The fifteenth-century Carelli spire was the first to be built.

Starting from the apse, which dates back to the 14th century, the sides gradually become later as they approach the facade, until the 17th century. The external buttresses are crowned with spiers and linked to the base by several horizontal bands. At the top is a frame with polylobed arches on corbels with anthropomorphic and zoomorphic figures. Between the buttresses, high up, are the windows that illuminate the aisles.

The apse is polygonal and framed by the bodies of the two sacristies, which are crowned by the more ancient spiers. The apse is illuminated by three enormous large windows with marble ribs that draw the rose windows (by Filippo degli Organi, beginning of the 15th century) in the ogive. The central window, with the manta of the Viscontis, is dedicated to the Incarnation of Christ.

 

Facade

The facade in itself bears witness to the complex building history of the Duomo complex, with the sedimentation of centuries of Italian architecture and sculpture.

Five backgrounds suggest the presence of the naves, with six buttresses (double at the ends and around the central portal) surmounted by spiers. The construction of the facade began in 1590, under the direction of the architect Pellegrini, in late Mannerist style, then continuing in the first half of the seventeenth century under the direction of Richini and Carlo Buzzi. The five portals and part of the windows above, crowned with a broken tympanum, date back to that period. The bas-relief decoration of the portals was sculpted in the times of Archbishop Federico Borromeo based on drawings by Cerano. The bases of the central buttresses are decorated with seventeenth-century reliefs, with telamons designed by Carlo Buzzi. The reliefs on the bases of the side buttresses are instead from the 18th and 19th centuries. In fact, starting from the mid-seventeenth century the works proceeded slowly due to the heated debate on the choice of the project to adopt. The conclusion, in neo-Gothic style, took place starting from 1805 on Napoleon's orders. The three neo-Gothic windows, built on a project by Soave and then by Amati, belong to this period. The statues of Apostles and Prophets on the shelves are all from the 19th century. From the first decade of the 19th century are the two neoclassical statues that decorate the balustrade of the central window, the Mosaic Law by Acquisti and the New Law by Camillo Pacetti. Some scholars argue that this statue was one of the main sources of inspiration for the creation of the New York Statue of Liberty. The last act of completion consists of the twentieth-century bronze doors. The central one, with light neo-Gothic lines, dates from 1906, while the other four were built after the war.

They range from the Late Renaissance of Tibaldi, to the Baroque of Francesco Maria Richini, to the Napoleonic neo-Gothic of Acquisti. In 1886 the 'Grande Fabbrica' announced an international competition for a complete reconstruction of the facade in Gothic style and in October 1888 the jury chose Giuseppe Brentano as the winner, a young pupil of Boito. The project, conceived as a model for French cathedrals, is still visible in the right aisle of the Cathedral. Although the marbles had already been ordered and the works had been prepared, also due to the premature death of Brentano, the realization of the project was frozen. Subsequently, the strong controversies that arose at the time of the dismantling of the Baroque portals ended up blocking it completely. The only part of the project completed, the bronze portal by Lodovico Pogliaghi, was adapted with an addition to the seventeenth-century frame.

 

Decoration

The distinctive feature of the Milan Cathedral, in addition to the form of compromise between Gothic verticality and traditional Lombard horizontality, is the extraordinary abundance of sculptures. Masters from different backgrounds dedicated themselves to what is an incomparable sample of statuary from the 14th to the 20th century, especially at the beginning, with examples ranging from Campione masters to the dry ways of Giovannino de' Grassi, to then move on to the soft and cosmopolitan style by the Bohemian and Rhenish masters and by Michelino da Besozzo himself, up to the examples of Renaissance, Baroque and Neoclassical sculpture, with even some Art Deco works from the 1920s and 1930s.

The other grandiose decorative cycle concerns the stained glass windows. The cathedral contains, with its fifty-five monumental stained glass windows, an extraordinary testimony to the history of glass art from the beginning of the fifteenth century to the end of the twentieth century. Over the centuries, master glassmakers of the Italian, Flemish and German schools collaborated in their production, often in collaboration with important painters who supplied the cartoons for the stained glass windows, such as Giuseppe Arcimboldo, Pellegrino Tibaldi and others.

 

Facade decoration

Gate of the Edict of Constantine
On the facade, starting from the external base on the left, the reliefs portray:

Death of Absalom
Samson removes the gates of Gaza
Samson eats the lion
Cain's sacrifice
Abel's sacrifice

The tympanum of the left portal is decorated with reliefs of Esther ad Assuero based on a design by Giovanni Battista Crespi known as il Cerano, while the Door of the Edict of Constantine dates back to 1948 and is the work of Arrigo Minerbi. It was begun by the sculptor in 1937 but only inaugurated after the war. In fact, Minerbi had been removed due to racial laws, being of a Jewish family. The door is made up of twelve rectangular panels, in addition to the upper pediment in the middle of which stands the figure of Constantine I. At the bottom are portraits of the six bishops of Milan preceding the edict of Constantine, among whom are recognized Saint Anatalone and Saint Calimero. Going up, you can see the tortures and persecutions suffered by the Christian martyrs before the edict. In the center are therefore the tables of the edict, promulgated in Milan in 313 AD, and above it the liberation of the Christians and their exultation. At the top, the apotheosis of Constantine.

Gate of Sant'Ambrogio
The second base has reliefs of:
Noah's sacrifice
David with the head of Goliath
Babel tower

The frieze above the portal shows Sisara and Jael, also designed by Cerano and the bronze door with reliefs on the Life of Sant'Ambrogio is by Giannino Castiglioni (1950).

Mary's Gate
The third basement has:
Brazen Serpent
Solomon's bed
symbolic figures

The central portal has pilasters richly decorated with motifs of flowers, fruit and animals, and a tympanum with the Creation of Eve, designed by Cerano. The bronze door is by Lodovico Pogliaghi and presents Stories from the life of Mary among floral reliefs. It was the first to be built and was inaugurated in 1906. It had been carried out as part of the project to renovate the facade designed by Brentano. When the project was abandoned, it was adapted to the ancient seventeenth-century portal with the addition of the upper gable, pierced, with the coronation of Mary among angelic choirs. The door represents, on the right wing, the painful episodes, with the Pietà in the centre, while on the left, the joyful episodes, with the Assumption in the centre. The episode of the Annunciation still bears the signs of war damage caused in 1943 by an air raid on the city.

Gate of the battle of Legnano
In the fourth base, the marble frieze crowning the portal portrays Judith beheading Holofernes, designed by Cerano, while the bronze portal from 1950 was begun by Franco Lombardi and completed by Virginio Pessina, with panels depicting the history of Milan from the destruction of Barbarossa to the victory of Legnano.

The reliefs of the fourth base portray:
Tower of David
Moses causes the waters to flow
Dream of Jacob

Door of the History of the Cathedral
The frieze of the portal shows Solomon and the Queen of Sheba by Gaspare Vismara, based on a design by Cerano. The bronze door with Episodes from the history of the Cathedral is by Luciano Minguzzi (1965).

The sixth base, external to the right, has reliefs of
Burning bush
Expulsion from Paradise on Earth
Cluster of the Promised Land
Moses saved from the waters
Raphael and Tobias

Higher up, the large statues relating to the Old Testament by Luigi Acquisti stand out.

 

Outdoor statues

The whole exterior is decorated with a very rich sculptural kit. Statues and busts are found on the corbels of the window splays, on the buttresses statues covered by marble canopies (below) and 96 "giants" (above), on which gargoyles figured as monstrous creatures soar. Other statues are found on the spiers, both crowning and in the niches. The complex of sculptures is an extraordinary art gallery in Milan between the fourteenth and neoclassicism, in the creation of which Lombard, German, Bohemian, French (including Burgundian), Tuscan, Venetian and Campione masters took part.

Among the most important statues are:

Right side
From the right side, second buttress below Sant'Ambrogio by Carlo Simonetta (1649).

Internal architecture

The interior is divided into five naves, and the transept into three. The presbytery is deep and surrounded by an ambulatory, next to which the two sacristies open. The central nave is twice as wide as the lateral ones, which are of slightly decreasing height, so as to allow the opening of small pointed arch windows in the clerestory, above the arches of the vaults, which illuminate the interior in a diffused and soft way . The triforium is missing.

The fifty-two polystyle pillars divide the naves and support the ribbed vaults painted with a Gothic tracery. This decoration was begun in the apse (mid-fifteenth century), continued in the lantern (1501) and again in the seventeenth, up to the additions and remakes by Achille Alberti and Alessandro Sanquirico (from 1823). It has not been reinstated since 1964.

Very original are the monumental capitals in niches and spires with statues, which decorate the pillars along the central nave, the transept and the apse. Some capitals are double-registered, with statues of saints in the niches surmounted by statues of prophets in the cusps. The other pillars have plant motif decorations.

 

Flooring

There is no trace of the original medieval floor but according to the famous architect Beltrami, who later carried out an important renovation between 1914 and 1920, the current geometric decoration, originally commissioned from Tibaldi in 1567, would be influenced by the design previous lost: in fact the geometric layout, with the exception of the rosettes and bells that stand in the way of the geometric lines, recall a motif typical of the late fourteenth or early fifteenth century. In fact, Beltrami recognizes in the decoration of the floor of the Cathedral a great resemblance to that typically late fourteenth century that covers the back wall of the loggia of the castle of Pandino near Cremona.

The design of the current floor was commissioned on 24 July 1567 to Tibaldi (1527-1596) following the provisions issued by San Carlo for the decoration of the Cathedral, but the works began in 1584, ending, with variations, only between 1914 and 1940. It is a complex mix of light and dark marbles, including black from Varenna, white and pink from Candoglia, and red from Arzo (originally, now almost completely replaced by red from Verona). Tibaldi also defined the side altars, the mausoleums, the choir and the presbytery (rearranged in 1986), following the requests of Cardinal Borromeo. The interior today has an aspect that is mainly influenced by this era, linked to the period of the Counter-Reformation. In the 18th century some monuments were transferred to the bays towards the facade, recently completed.

 

Interior decoration

Squares of San Carlo
In November, the period dedicated to San Carlo Borromeo (celebrated on November 4), the so-called "Quadroni di San Carlo" are exhibited in the Cathedral, a cycle of fifty-six large canvases that celebrate the life and miracles of the patron saint of Milan. Made during the seventeenth century, they constitute the most important pictorial cycle of the Lombard Baroque.

The first cycle was commissioned between 1602 and 1604 by the Fabbrica del Duomo, just eighteen years after the saint's death, to some of the most successful painters of Milan at the time: Cerano (four paintings), Duchino (7) , the Fiammenghino (5), Carlo Buzzi (2), Carlo Francesco Procaccini (1), and others. This cycle includes the 28 largest canvases (6 meters by 4.75), which narrate the facts of the life of Blessed Charles. To this was added the second cycle, the Miracles of San Carlo, of as many paintings concerning his miracles and healings. These paintings are smaller than the first series and measure approximately 2.4×4.4 metres. They were built between December 1609 and November 1610, when St. Charles was canonised. The executors of the first cycle were joined by Giulio Cesare Procaccini, author, with Cerano, of the canvases most appreciated by the critics.

In addition to this series of teleri, two other large cycles were painted in the Baroque era: the cycle of the Finding of the true cross, which was exhibited on the occasion of the feast of the Sacred Nail, and the cycle of the SS. Sacramento, narrating wonders and miracles of the SS. Sacrament. The custom of exhibiting them ceased with the Second World War and they are currently housed in the diocesan museum in Sant'Eustorgio.

 

Counter facade

The median portal, on the counter-façade, was designed by Fabio Mangone at the beginning of the 17th century, but only built in 1820. The crowning features the statues of Sant'Ambrogio and San Carlo, by Pompeo Marchesi and Gaetano Monti respectively. On the attic a plaque commemorates the two consecrations, of 1418 and 1577. The stained glass windows of the classical windows of the first level are from the 19th century, made by the Bertini brothers, with Saint Charles, Saint Ambrose and Saint Michael, while it is by Mauro Conconi Saint Thecla. Those of the neo-Gothic windows are from the fifties of the twentieth century, made by the Hungarian Hajnal, recovering the bright colors of the medieval tradition[10]. On the sides they represent the Church and the Synagogue, while in the center the Trinity with an unusual iconography. The Assumption in the central window was made from cartoons by Luigi Sabatelli.

 

Sundial

Near the entrance to the Cathedral is the sundial with the Capricorn symbol, made up of a brass strip set into the floor which crosses the nave and which rises three meters up the left (north) wall. In the south-facing wall, at a height of almost 24 meters above the floor, a hole is made through which, at solar noon, a ray of light is projected onto the floor strip. To prevent the light entrance hole from falling into shadow on certain days of the year, the marble arch is missing on the south side of the church. Marble slabs are installed on the sides of the metal line indicating the signs of the zodiac with the dates of entry of the sun.

The instrument was made in 1786 by the Brera astronomers, restored several times and modified in 1827 following the reconstruction of the floor of the Cathedral.

 

External right aisle

funerary monuments
In the first bay of the external right nave is the sarcophagus of Archbishop Ariberto da Intimiano (1045 m), who ruled the fate of the Municipality of Milan from 1018 to 1045 by uniting the temporal and episcopal power over the city. The tomb, in simple rough serizzo stone without ornaments, is surmounted by a copy of the famous crucifix in gilded copper foil, now in the Cathedral Museum, originally donated by Ariberto to the monastery of San Dionigi. The cross, a valuable proto-Romanesque work, bears an iconic image of Christ still in the Byzantine style. On the top of the cross, in the two tondos, are the personifications of the Sun and the Moon. At the end of the trefoil arms of the cross are the figures of Mary and John, while at the feet of Christ is an image of Ariberto himself who brings the convent of San Dionigi as a gift. According to tradition, the cross was believed to be the one carried on the Carroccio during the battle of Legnano in 1176 against the emperor Federico Barbarossa.

On the left, a small seventeenth-century marble bears an inscription that recalls
«The beginning of the Domo of Milan was in the year 1386.»

The stained glass window is decorated with Stories of St. John the Evangelist, taken from Jacopo da Varazze's Legenda Aurea, recomposed and restored here in the 1960s. The stained glass window was commissioned by the College of Notaries to Cristoforo de' Mottis who created it in the period 1473-1477. It is one of the most beautiful stained glass windows of the full Renaissance preserved in the cathedral. The humanist taste that pervades the episodes of the saint's life is manifested in the elegant fifteenth-century costumes and in the splendid architectures of classical taste rendered with rigorous perspective.

In the second bay follow the sarcophagus of the archbishop Ottone Visconti, considered the founder of the Lordship of the Visconti, which began with the battle of Desio in 1277 in which the archbishop defeated the powerful Torriani family. Subsequently, Giovanni Visconti, a descendant of Ottone, archbishop of Milan from 1342 to 1354, was also buried in the same sepulcher. Santa Tecla.

The stained glass window is decorated with Stories from the Old Testament by Lombard and Flemish masters dating back to the mid-16th century, and glass depicting the passion of Christ inspired by Albrecht Dürer's engravings. They come from the large apsidal windows, rebuilt during the 19th century.

In the third bay there is the list of the archbishops of Milan and a stained glass window with other Stories from the Old Testament, by Lombard (Arcimboldi), Rhenish and Flemish masters (mid-sixteenth century).

The fourth bay features the sarcophagus of Marco Carelli, a patron of the arts who at the end of the 14th century donated thirty-five thousand ducats to the Fabbrica del Duomo to speed up the construction work. The monument, designed by Filippino degli Organi in 1406, is a masterpiece of late Gothic sculpture. The lid depicts the deceased in a recumbent position according to the custom of the time, while on the sides there are eight statues representing the evangelists and doctors of the Church, sculpted by Jacopino da Tradate within elegant aedicules divided by pinnacles.

The fourth window collects episodes from the Old Testament, created by Lombard craftsmen in the 16th century.

The fifth shows a plaque with Giuseppe Brentano's late 19th-century project for the facade, never realized due to the opposition encountered to the demolition of the present facade which the project represented was supposed to replace.

Following on the left is the Renaissance tomb of Gian Andrea Vimercati, who died in 1548, decorated with a Pietà and two busts of Bambaia (first half of the 16th century).

The fifth "foppesca" window (even if it is not the direct work of Vincenzo Foppa), is decorated with Stories from the New Testament (1470-1475) by Lombard masters who were inspired by the works of the famous painter with influences from the Ferrara school. It develops, starting from the Annunciation at the bottom up to the Crucifixion at the top, the Story of the life of Christ, and is considered one of the most beautiful and best preserved Renaissance stained glass windows in the Cathedral. In it the grisaille technique is particularly evident, with which the ancient executors transferred onto the glass the drawing that the painters made on the cartoons that served as a model.

 

Pilgrims' altars

In the sixth span there is an altar called Sant'Agata composed of composite columns and a pediment, the work of Pellegrino Tibaldi, where there is the altarpiece by Federico Zuccari with San Pietro visita in Sant'Agata prison (1597).

The sixth window is among the few from the Renaissance period to have been fully preserved. It tells the stories of Saint Eligius, patron saint of goldsmiths. It was in fact commissioned by the Collegio degli Orafi to Niccolò da Varallo, who executed it between 1480 and 1489). Each episode has a title in Latin at the bottom. The depictions are characterized by simple and familiar tones, many of which show scenes of daily life from the 15th century.

In the seventh bay is the Altar of the Sacred Heart, also designed by Pellegrini, with a marble altarpiece by Edoardo Rubino, placed in 1957. The stained glass window, designed in 1958 by János Hajnal, commemorates the blessed cardinals Schuster and Ferrari, both archbishops of Milan.

The eighth span presents the Altar of the Madonna, also designed by Pellegrini, with the marble altarpiece of the Virgo Potens, the work of a Rhenish author perhaps from 1393, called di Jacomolo, from the name of the donor. The stained glass window with Stories of Sant'Agnese and Santa Tecla is the work of Pompeo and Guido Bertini from 1897-1905. Under the table of this altar is the body of Blessed Cardinal Alfredo Ildefonso Schuster, archbishop of Milan from 1929 to 1954.

 

External left aisle

In the first bay of the external left nave are the sundial and the stained glass window with the Stories of David by Aldo Carpi (1939).

The second bay houses the baptistery, the work of Pellegrini, which is made up of a small temple with a square base, supported by four Corinthian columns, with trabeation and tympanums on the four sides. In the center is the tub, made up of a Roman porphyry sarcophagus. On the wall are two marble slabs in Verona red, with reliefs of the Apostles, probably the work of Campione masters from the end of the 12th century, from Santa Maria Maggiore. The stained glass window was reassembled with fragments from the 16th century and illustrates events from the New Testament, which are part of the cycle of the Passion of Christ, coming from the apse window dedicated to the New Testament which was redone in the 19th century.

In the third bay is the monument to the archbishops Giovanni, Guidantonio and Giovannangelo Arcimboldi, attributed to Galeazzo Alessi or Cristoforo Lombardo (1599). The stained glass window portrays the Battle between the Archangel Michael and the devil and is by Giovanni Domenico Buffa (1939). Unique among all the large windows, it portrays a single episode along its 17 meters of height. It is characterized by tones of heated expressionism, with which the assault with which the Archangels, represented above under the guidance of Michael on a dazzling white steed, is precipitating the demons into the flames of the 'hell.

In the fourth bay, the stained glass window with the Stories of the Four Crowned Saints is interesting, a Mannerist work carried out to a design by Pellegrino Tibaldi in 1567. The cartoons by Pellegrini's hand, which Corrado Mochis transposed onto glass, are still kept in the Pinacoteca Ambrosiana. In the theatrical pose of the vigorous figures that animate the episodes from the life of the saints, the Roman derivation of Tibaldi's style is clearly manifested, and in particular the Michelangelo ancestry of the powerful representations. From below, the Miracle of the chisels, the Baptism in prison of the four converted sculptors, The four saints at work, the Judgment of the four saints, the Martyrdom before the emperor Diocletian are shown.

The fifth conserves the 1832 reconstruction of the aedicule of the Tarchetta dell'Amadeo, the original fragments of which are now in the Castello Sforzesco. The sixteenth-century stained glass window is dedicated to the Glories of the Virgin. It was created by Pietro Angelo Sesini and Corrado de' Mochis on cartoons by Giovanni da Monte, a pupil of Titian. One of the episodes still bears the artist's signature (G.M.F., Giovanni da Monte fecit). Like other Mannerist windows executed during the episcopate of Carlo Borromeo, it expands the episodes represented on several panels, increasing their monumentality. Chiara is the derivation from Titian in many scenes, such as the famous Assunta dei Frari. The Pentecost, the Transitus and the Assumption (1565-1566) are depicted from below.

 

Altar of the Crucifix of San Carlo

As in the right aisle, the last three bays of the left aisle are also occupied by three late Mannerist altars designed by Pellegrino Tibaldi, from the time of San Carlo.

In the sixth bay is the Altar of the Crucifix of San Carlo, which contains the famous wooden crucifix that Carlo Borromeo carried in procession during the plague of 1576, as remembered by the inscription:
«Crucem hanc S.Carolus grassante lue per urbe circumtulit MDLXXVI»

The decoration of the altar is completed by two nineteenth-century statues of saints in the niches between the black marble columns, while the statuary crowning the tympanum dates back to the sixteenth century. The remains of Cardinal Carlo Maria Martini now rest under this altar, as requested by him to Monsignor Luigi Manganini (Archpriest of the Cathedral).

The stained glass window is decorated with the Stories of Saint Helena, by Rainoldo da Umbria and Perfundavalle (1574), narrating the discovery of the Cross. The stained glass window is divided into only three large episodes, which narrate the story of Constantine's mother, who, according to tradition, found the Cross of Christ during a pilgrimage to Jerusalem. The first episode below shows Saint Helena freeing the prisoners; The scene of the Finding of the Cross follows further up, and at the top the Miracle performed by the Holy Cross.

 

Altar of St. Joseph

In the seventh bay, the altar and the stained glass window are dedicated to Saint Joseph. Framed by two caryatids, is the sixteenth-century altarpiece of the Marriage of the Virgin by Enea Salmeggia known as Talpino, a painter from Bergamo who was a pupil of Peterzano. On the sides, the statues of Aaron and David by Francesco Somaini which can be dated after 1830. The statues of the Prophets that surmount the tympanum, on the other hand, are from the late Mannerist period, as is the stained glass window with the Stories of Saint Joseph by Valerio Perfundavalle from Louvain, author of both the cartoons than the transposition on glass. Commissioned by St. Charles, it is divided into four scenes: it depicts the Annunciation from below, visible among the statues, the Visitation, the Nativity and the Flight into Egypt. It is the last of the stained glass windows from the Mannerist period preserved in the Cathedral, made in 1576. Under the table of this altar is the body of Saint Mona, the third-century archbishop of Milan, while in the pavement in front of the altar is the tomb of Cardinal Giuseppe Pozzobonelli, archbishop of Milan from 1743 to 1783.

 

Altar of Saint Ambrose

The last bay houses the Altar of Sant'Ambrogio, also by Pellegrini, with the altarpiece of Sant'Ambrogio imposing penance on Theodosius by the Urbino painter Federico Barocci (1603). It shows the emperor Theodosius kneeling in front of Saint Ambrose, his scepter and crown placed on the ground. It refers to the penance that the bishop of Milan, then the capital of the empire, imposed on the emperor for having ordered a massacre among the population of Thessalonica. The episode, frequently represented, was intended as a metaphor for the subordination of imperial power to papal power. Above the broken tympanum of the altar, supported by polychrome marble columns with bronze capitals, are statues of Bishops. On the stained glass window, rebuilt in the 19th century, are the Stories of Sant'Ambrogio by Pompeo Bertini. Compared to the previous ones from the Renaissance period, the stained glass window is characterized by the use of duller colors and lighter shades, among which the red of Ambrogio's tunic stands out in each episode. All the scenes show, both in the costumes and in the architecture in the background, a particular attention in the historical reconstruction of the events set in late imperial Milan and a rigorous perspective construction. Under the table of this altar is the body of San Dionigi, archbishop of Milan from the 4th century.

 

South arm of the transept

Medeghino's funeral monument
Noteworthy in the right transept is the funeral monument to Gian Giacomo Medici known as the Medeghino, the work of Leone Leoni from 1560-1563. It was commissioned by Pope Pius IV Medici, brother of the leader. It is composed of a backdrop of Carrara marble, with a base where two Tuscan columns in red breccia d'Arzo rest, which support an entablature so as to create an aedicule. Below it is the bronze statue of Medeghino, with his lame leg covered by a cloak. The work, which represents an interpretation of Michelangelo's style, was to have been accompanied by the sarcophagus in the upper part, which was not built in compliance with the anticipated regulations of the Council of Trent regarding burials in churches. On the sides there are two other bronze statues: on the right the Allegory of Peace with a bas-relief of the Ticino, on the left the Militia with a bas-relief of the Adda. The two rivers recall two famous battles won by the leader. The upper part is decorated with two epigraphs dedicated to Medeghino and his brother Gabriele. The central gable has a bas-relief of the Nativity, crowned by a Medici coat of arms supported by two putti. Two other taller veined marble columns support the bronze statues of Prudence (right) and Fame (left).

The stained glass window is the work of Giovanni Battista Bertini (1849) and presents Stories of Saints Gervasius and Protasius. The adjacent sixteenth-century altar in ancient polychrome marble is interesting, with two orders of niches and small columns, built by Pope Pius IV as a gift for his nephew Carlo Borromeo. It is said that the saint celebrated a weekly mass there in honor of his family members. The Borromeo coat of arms, "Humilitas", is in fact placed on the top of the altar. It is made up of precious oriental marbles and semi-precious stones, such as chalcedony, serpentine and lapis lazuli. The golden statuettes that adorned it have been transferred to the Cathedral Museum.

 

Chapel of St John the Good

At the end of the median nave is the apse from the second half of the seventeenth century, where the chapel of San Giovanni Bono opens, so well known in local tradition. It was Carlo Borromeo who wanted the relics of the saint to be transferred to this place, in place of the previously existing Gothic portal. The saint of Ligurian origin was simultaneously archbishop of Milan and Genoa in the seventh century. He is remembered for having brought the bishopric back to Milan, which had been moved to Genoa due to the Lombard invasion. His body is now buried inside the altar dedicated to him, inside a crystal case. The current appearance of the chapel dates back to the first half of the eighteenth century when the elaborate decoration that characterizes it was created. The statue in the center of the altar, which portrays St. John the Good crushing the devil under his feet, was created by Elia Vincenzo Buzzi in 1763. The monumental marble aedicule which contains the statue of the saint was erected so as to form a symmetrical pendant compared to the previous altar of the Madonna dell'albero located in the apex of the northern transept. On the sides are the marble groups, also by Buzzi, which recall the theme of victory over the devil. On the right is St. Michael the Archangel who knocks down Lucifer, on the left the Guardian Angel who, still trampling on the demon, shows the child the right path. In the center of the tympanum is the verse from the Gospel of John taken from the parable of the good shepherd:
«Ego sum pastor bonus»
(John, 10.10)

The Baroque altar is crowned by statues of saints and two angels holding the hat, an ancient archiepiscopal ornament. The decoration is completed by a series of high reliefs in Carrara marble, which represent Episodes from the life of the saint alternating with busts of the cardinal Virtues, created by various sculptors between the seventeenth and eighteenth centuries (Giuseppe Rusnati, Giovan Battista and Isidoro Vismara, Carlo Simonetta and others ). Among the themes represented are the birth, the meeting with Queen Teodolinda, the expulsion of the Arians, the trip to Rome. The reliefs on the segments of the vault, from the same period, represent the Archbishops in Glory among the Angels, while in the under arch is the blessing Christ. The three painted windows, with Stories of St. John Bono were made by Bertini in the mid-nineteenth century (1839-1842).

The left aisle of the transept, on the other hand, has a side exit divided into three passages: the central one leads to the underground passage for the Archbishopric, made for Carlo Borromeo. Here the stained glass window, with Stories of Saint Catherine of Alexandria was designed by Biagio and Giuseppe Arcimboldo and created by Corrado Mochis (1556). This nave houses three important works from the Mannerist period: the Altar of the Presentation of the Virgin, by Bambaia, the Altar of Sant'Agnese, by Martino Bassi, and the San Bartolomeo by Marco d'Agrate.

 

Altar of the Presentation of the Virgin

The altar of the Presentation of the Virgin, on the right, maintains the appearance given to it in 1543 when it was commissioned to Agostino Busti, known as Bambaia, by Canon Vimercati. Next to the altar was the funerary monument of Vimercati, also of Bambaja, now transferred to the right aisle of the church. It has the shape of a classical temple, entirely composed of white marble, supported by polychrome marble columns. In the center is the relief with the Presentation of Mary. The scene is conceived as if it were the interior of the temple of which the columns and the pediment of the altar constitute the external part. Mary as a child is portrayed below in the center of her, in the act of climbing the ladder to the top of which the priest surrounded by the faithful is ready to welcome her with open arms. On the sides of the staircase are, on the left, the parents Anna and Gioacchino, and on the left a group of faithful who bring offerings. The characters are characterized by a highly realistic and expressive representation, evident in the faces with lively expressions. In the perspective representation of the interior of the temple, the inspiration for the fake apse built by Bramante in San Satiro, a short distance from the Cathedral, is evident. Bambaja is also the author of the statues that crown the altar, with the Virgin, Saint Paul, Saint John the Baptist and two female saints, and of Saint Martin in the lateral niche. Instead, they are by Cristoforo Lombardo Santa Caterina in the right niche and the reliefs at the bases of the columns, very deteriorated, with the Birth and Marriage of the Virgin. The frontal with the Birth of the Virgin is a nineteenth-century work by Antonio Tantardini.

The stained glass window above with Stories of San Martino and the Presentation of the Virgin is from the late sixteenth century and is by various artists. In the middle of the window stand the Prophets attributed to Michelino da Besozzo, which are among the oldest panels preserved in the Cathedral.

In front of the Medici Mausoleum there is perhaps the most famous statue of the whole Cathedral: the San Bartolomeo Scorticato (1562), by Marco d'Agrate, where the saint shows the skin thrown like a stole on his shoulders. It bears the inscription on the base
«Non me Praxiteles sed Marcus finxit Agratis»
(Praxiteles did not sculpt me but Marco d'Agrate)

The following Altar of Sant'Agnese, completed by Martino Bassi, is decorated by the marble altarpiece of the Martyrdom of Sant'Agnese, by Carlo Beretta (1754)

 

North arm of the transept

In the right aisle of the north arm of the transept there is an altar designed by Tibaldi, dedicated to the saint to whom the church that was demolished to make room for the cathedral was dedicated, Santa Tecla. The polychrome marble altar, characterized by angelic caryatids holding up the broken tympanum, is from the late sixteenth century, as are the statues above, while the two saints on either side of the altar are from the nineteenth century. In the center is the marble altarpiece with the martyrdom of Santa Tecla among the lions, a late Baroque work sculpted by Carlo Beretta in 1754, and an 1853 frontal by Antonio Tantardini.

The second altar, from the early 16th century, is dedicated to Santa Prassede, represented together with San Carlo at the foot of the Crucifix and saints in the marble altarpiece by Marcantonio Prestinari (1605). The Renaissance window above, decorated with the Stories of San Giovanni Damasceno, is among the most valuable preserved in the cathedral. It was commissioned by the college of apothecaries in 1479 to Nicolò da Varallo. The panels with the life of the saint show a gallery of happy portraits of characters, representative of the humanist period in which they were drawn, and inserted in balanced classical architectures represented with perspective rigor.

From the back wall a small door gives access to the Scala dei Principi, which in ancient times was reserved for the entrance of the most illustrious characters, while today it leads to the lift for the terraces. The stained glass window with Stories of San Carlo is from 1910.

 

Chapel of the Madonna dell'Albero

In the middle nave it is closed by an apsidiole which contains the chapel of the Madonna dell'Albero, designed by Francesco Maria Richini (1614) and built with some modifications by Fabio Mangone and Tolomeo Rinaldi. Until the time of Carlo Borromeo, the apse was occupied by the large portal called "Compedo". The archbishop ordered it to be closed, to prevent it from being used to cross the cathedral from north to south, in particular by visitors to the nearby market of the greenery, who used this door and the other opposite, on the south apse, as shortcuts as an alternative to the external tour of the cathedral. The bas-reliefs that decorated the walled-up portal, which constitute an exceptional testimony of the Lombard school of the transition phase between the Renaissance and Mannerism, were reused to decorate the internal facade of the arch that frames the chapel of the Madonna dell'Albero: from the left Nativity of the Virgin, Presentation in the Temple by the Bambaia school, Crib by Cristoforo Solari, Christ among the Doctors by Angelo Marini and Wedding at Cana by Marco d'Agrate, alternating with busts of prophets. The vault is thickly covered with teeming Baroque reliefs by Gian Andrea Biffi, Giovanni Pietro Lasagna and Prestinari (1615-1630). The altar is decorated with a Madonna and Child by Elia Vincenzo Buzzi (1768). The three windows with Stories of the Virgin were entirely rebuilt in the 19th century by Giovanni Battista Bertini (1842-1847).

In front of the chapel are the tombstones of various archbishops, including Federico Borromeo and the Trivulzio candelabrum, a majestic bronze work donated by the archpriest G. A. Trivulzio in 1562: it is a masterpiece of Gothic sculpture, mostly made in the 12th century century and attributed to Nicolas de Verdun or to Rhenish artists working between the fourteenth and fifteenth centuries. The foot rests on chimerical animals and tendrils and spirals run along the body framing scenes from the Old Testament, the Liberal Arts, Rivers and an Adoration of the Magi.

In the left aisle is the Altar of Saint Catherine, the only largely original Gothic altar in the cathedral. It is decorated by the statues of San Girolamo and Sant'Agostino, attributed to Cristoforo Solari (beginning of the 16th century), and the statuettes of the end of the 14th century attributable to Giovannino de' Grassi.

The window on the left of the north apse is divided into two parts horizontally: the upper part tells Stories of Saint Catherine of Siena, conceived and conducted by Corrado Mochis. Although dated 1562 it shows affinities with the fifteenth-century stained glass windows narrating the lives of saints. All the episodes are in fact enclosed in a single panel each, mostly in interior scenes characterized by a rigid perspective. The lower part, on the other hand, shows a freer and more updated style, with episodes from the Life of the Madonna, drawn by Giovanni da Monte in the same period (1562-1567). The summit rose window and the trefoils that conclude the window appear in a typically Mannerist taste, decorated with fantasies of cherubs, grotesques and garlands of intertwined fruit.

To the left is the funeral monument of Archbishop Filippo Archinto, predecessor of Carlo Borromeo, whose severe bust dominates the aedicule designed by Baldassarre da Lazzate (around 1559). The stained glass window dedicated to the Apostles was made on cartoons by the Crema painter Carlo Urbino of the Mannerist period (1567). Unlike the other stained glass windows, its panels are not decorated with narrations of evangelical or hagiographic episodes, but rather show the twelve apostles full-length, as well as depictions of other saints below. At the climax is the Coronation of the Virgin. The monumental figures, mostly represented in niches, represent a masterpiece of the artist's maturity, active in numerous Milanese churches. They stand out in particular for their chromatic richness and plastic definition, thanks also to the skilful transposition on glass by de' Mochis.

 

Lantern

At the center of the church is the lantern by Giovanni Antonio Amadeo, 68 meters high and with an octagonal base, supported by four pointed arches and pendentives. The vault itself is supported by pointed arch lunettes and by four round arches, not visible, hidden by pointed arches.

The round frescoes in the spandrels with the Doctors of the Church are the work of the Lombard school of around 1560-1580. The profile of the arches houses 60 statues of Prophets and Sibyls are in late Gothic style from the second half of the fifteenth century and are influenced by Burgundian and Rhenish art, which seem to anticipate the Lombard Renaissance. The stained glass windows are from 1958 and depict the events of the Second Vatican Council.

 

Bells

The cathedral has three bells that play as many notes: E flat3 falling, B2 and an A flat2 very falling; together they make up the heaviest bell concert in the Lombard diocese (and also in the entire metropolitan province), with a total weight of 14,995 kilograms in bronze.
The main bell, dedicated to the Blessed Virgin Mary, was cast by Giovanni Battista Busca in 1582 and blessed by San Carlo Borromeo and has a diameter of 2.13 m. It is the seventh bell in Italy by weight.
The middle bell, dedicated to Sant'Ambrogio, was made in 1577 by Dionisio Busca and has a diameter of 1.76 m.
The smaller bell, dedicated to Saint Barnabas, believed to be the evangelizing Apostle of Milan, was cast by Gerolamo Busca in 1515 and has a diameter of 1.28 m.

These three bells are located in the interspace of the lantern between the internal vault and the external walls. They are not visible from the outside.
The bells, originally swinging and positioned on a bell tower located on the terrace above the main nave, demolished in 1868, are now fixed due to static problems and ring through the movement of the clapper.

On the terrace of the lantern, behind a spire, there is a fourth bell dedicated to Santa Tecla, cast in 1553 by Antonio Busca (the note emitted is a Si4).

 

Presbytery

The presbytery complex corresponds to the area enclosed by the ten apse pillars, and surrounded by the ambulatory. Its current appearance dates back to the last half of the sixteenth century. Its arrangement and the decorations that we see today were commissioned by Carlo Borromeo and carried out by his favorite architect, Pellegrino Tibaldi, according to the dictates of the Council of Trent. Further transformations were made in the eighties of the twentieth century, following the static restoration of the pillars of the lantern.

Today the presbytery is divided into two parts, with different functions. The festive presbytery has access from a semicircular staircase and occupies a part of the central nave and the old senatorial choir (where the civil magistrates and those of the confraternities met), with various floors recently repaved on the Pellegrini decoration.

At the highest point is the high altar, coming from the basilica of Santa Maria Maggiore, and consecrated by Pope Martin V on 16 October 1418, which marked the official start of the officiation of the new cathedral. The current elevated position was decided by Carlo Borromeo. It dates back to the period of the reconstruction of Milan after the destruction of Barbarossa, around the end of the 12th century. The Romanesque decoration, extremely simple, consists of ten marble slabs alternating with as many octagonal pillars, which support the large rectangular table. At the center of the altar is a relief found on the inner side of the slabs that compose it, which was part of a Roman-pagan sarcophagus from the 3rd century AD, already reused as the burial place of a Christian martyr, as evidenced by a cross on the bottom and a cartouche. It depicts a Roman in toga holding a cartouche, inside an aedicule.

The chair and the ambo, by the sculptor Mario Rudelli, are from 1985 and are accompanied by two sixteenth-century pulpits, designed by Pellegrini. Circular in shape, they surround the two pillars that support the lantern. Both are supported by four monumental bronze caryatids, which hold up the parapets made of embossed and gilded copper plates, as well as the canopies that crown their tops. The left was finished in 1585. It is dedicated to the New Testament and supported by the symbols of the Evangelists. The right, finished in 1602, has reliefs from the Old Testament and four caryatids with the Doctors of the Church. They are the work of Giovanni Andrea Pellizzoni and bronzes by Francesco Brambilla the Younger (1585-1599).

At the center of the presbytery area stands the Tempietto or ciborium of Pellegrini, which encloses the cylindrical tower tabernacle, a gift in 1561 from Pope Pius IV Medici to his nephew Carlo Borromeo. The temple has the shape of a small circular classical temple, supported by eight Corinthian columns, whose dome is adorned with statues of angels and crowned by the Savior. In its shape, it repeats the inner tabernacle, cylindrical, supported by four angels and entirely modeled with episodes from the life of Christ. On both sides of the ciborium are the two imposing silver statues of Saint Charles and Saint Ambrose, a masterpiece of Baroque sculpture and goldsmithing. The statue of San Carlo, dating back to 1610, was modeled by the sculptor Andrea Biffi and chiseled by the goldsmith Verova. The chasuble is finely decorated with twenty ovals which narrate the episodes of the saint's life. The Miter is adorned with pearls and precious stones donated by the faithful. The statue of Sant'Ambrogio, almost a century later (1698), has greater emphasis and expressiveness. The entire surface is closely chiseled and decorated with diamonds and hard stones.

The ciborium also marks the boundary with the Cappella Feriale, the other section of the chancel. It is a separate and intimate space created in 1986 in the old presbytery and in the choir, where the faithful can gather during the week's liturgies.

Even the wooden choir that delimits this area dates back to the sixteenth century and was commissioned by San Carlo. It is made up of a double order of carved stalls, the upper one for the canons, the lower one for the Chapter. They were carved by Giacomo, Giampaolo and Giovanni Taurini, Paolo de' Gazzi and Virgilio de' Conti on drawings supplied by Pellegrini, in 1567-1614. The reliefs tell 71 Episodes from the life of Saint Ambrose with as many figures of martyrs in the upper order, Stories of Milanese archbishops in the lower one.

 

Holy Nail

Suspended above the high altar, attached to the keystone, is the cathedral's most precious relic, the nail of the True Cross (Sacro Chiodo), which according to tradition was found by Saint Helena and used as a bit on Saint Helena's horse. Constantine I

The Sacred Nail is now kept in a niche contained in a copy of the gilded copper serraglia with the relief of the Almighty (today in the Cathedral Museum). Although suspended very high, a red light makes it visible from all over the cathedral. The nail is taken by the archbishop and shown to the faithful every 3 May, the feast of the "Invention of the Holy Cross" (i.e. the finding of the Cross), now it is carried in procession on 14 September, the feast of the Exaltation of the Holy Cross. To remove the nail from its case, the seventeenth-century nivola is used, a curious lift that is now mechanized, from which the celebration of the Nivola rite takes its name. Of the four nails of the True Cross, according to tradition, two others are found in the Iron Crown in Monza and in the basilica of Santa Croce in Gerusalemme in Rome. The fourth nail that would have held the inscription "INRI", from the most dubious tradition, would be found in the cathedral of Colle di Val d'Elsa in the province of Siena.

 

Organs

It can be said that the organ of the cathedral was an important endowment from the very beginning of the building. The first organ was already commissioned in 1395 to Martino degli Stremidi and was functional in 1397. Continuous modifications, additions and restorations followed. An arrival point is the work of Gian Giacomo Antegnati who between 1533 and 1577 built the north organ, with 12 registers and 50 keys, which was transported to its current position in 1579. In 1583 Cristoforo Valvassori was commissioned to l south organ (1584-1590), replacing the older one. The doors of the latter have large paintings: on the left with Stories of the Virgin and the Old Testament by Giuseppe Meda (1565-1581); on the right the Nativity and the Crossing of the Red Sea by Ambrogio Figino and Stories from the Old and New Testaments by Camillo Procaccini (1592-1602). The gilded carvings of the cases are by Giovan Battista Mangone, Sante Corbetta, Giacomo, Giampaolo and Giovanni Taurini.

The two large north and south organs were continuously remodeled, passing among other things from mechanical to pneumatic transmission up to the current electric one. They have eight large doors (four towards the presbytery and four towards the tornado) which can open or close to modulate the volume, reverberation and echoes. In the list of titular organists there is also the son of Johann Sebastian Bach, Johann Christian Bach. During the 19th century, the Serassi family also took part in the restructuring of the organ. Four more corps were added in 1937, so that all of them were commanded from the same console. However, the acoustic result was disappointing, to the point that the whole complex of organs was rearranged during the restructuring of the presbytery in the years 1985-1986. Today the four added organs are placed next to the two oldest ones, in new simple and linear wooden cases. The current console was placed under the sixteenth-century case on the right (south). The last renovation (that of 1986) was carried out by the Tamburini company.

The organ of the Milan Cathedral has 15,800 pipes and is one of the largest organs in the world. Next to this large organ, a second, small organ was added, located on the left side, next to the place where the choir takes its place, precisely to be close to the singers when a less imposing accompaniment than that made up of the main organ is needed.

 

Crypt

In the retrochoir, in front of the southern sacristies, the stairs leading down to the crypt open. At the end of the stairs, beyond the entrance to the Treasury, one passes into a vestibule rebuilt by Pietro Pestagalli in 1820, which gives access to the shrine of San Carlo, and to the crypt. The latter is a circular room designed by Pellegrini with a peribolos around the altar. The small room was used during the winter by the canons, in place of the choir above, due to the milder temperature. For this reason it was also called hyemal or winter choir. The circular chapel is occupied in the center by the altar, surrounded by eight red marble columns which support the vault entirely covered by a dense and refined stucco and fresco decoration. Leaning against the walls are the wooden stalls of the choir, of simple workmanship. A series of oval windows overlook the ambulatory above.

On the opposite side of the winter choir is the so-called Scuolo di San Carlo, a chapel with a flattened octagonal base, designed by Francesco Maria Richini in 1606. The entire upper band and the ceiling are decorated with silver foils with scenes from the life of St. Carlo, commissioned by Cardinal Alfonso Litta around 1670. The body of the saint is kept in a chiseled silver urn, with rock crystal walls donated by Philip IV of Spain. Cerano provided the drawings of the angels and figures that adorn the sarcophagus, a masterpiece of Baroque goldsmithing. St. Charles lies in pontifical dress, with a tourmaline and diamond cross donated by Maria Theresa of Austria. The silver mask was modeled after the original wax mask taken after her death.

 

Ambulatory

Retrochoir with the Stories of Mary
The ambulatory is the gallery that runs behind the choir, illuminated by the three immense large windows in the apse. Its inner side is made up of Pellegrini's marble retrochoir, semicircular in shape, made up of two orders superimposed one on top of the other. The lower order, believed to be by Galeazzo Alessi, is decorated with herms with angelic features, cherubs and lions' heads in Mannerist style. In it there is access to the crypt, and the crown of large windows that give it light. The upper order is decorated with 32 caryatids in the form of angels designed by Pellegrini himself and made by Francesco Brambilla the Younger. They are interspersed with tables in relief, with seventeen Stories of Mary and ten Marian symbols, sculpted at the time of Federico Borromeo. The story unfolds from the southern pulpit, and constitutes an important cycle of Baroque sculpture. There are represented the Nativity of Mary, the Presentation in the Temple, the Marriage, the Annunciation, the Visitation, the Dream of Joseph, the Nativity Scene, the Circumcision, the Flight into Egypt, the Dispute with the Doctors, the Wedding at Cana, the Crucifixion, the Deposition, the Apparition of the Risen One to the mother, the Transit of the Virgin, the Assumption, the Coronation of Mary. Marian symbols are placed between the episodes relating to Mary's life, with scrolls featuring extracts from Sirach. They were sculpted by the most popular Milanese authors of the time: Gian Andrea Biffi, Marcantonio Prestinari, Giovanni Pietro Lasagna, Giovanni Bellanda, Gaspare Vismara.

 

Monuments to popes and cardinals

The first span contains the Monument to Pope Pius XI Ratti, Archbishop of Milan in the six months preceding his election as Pope, of which it represents a faithful portrait. The statue, sculpted by Francesco Messina in 1969, portrays him in solemn pontifical robes with the tiara and the keys of St. Peter while imparting the blessing, taking up the Gothic monument of Martin V not far away. Here is the access to the southern sacristy.

The Monument to Pope Paul VI dates back to 1988, and commemorates Giovanni Battista Montini, archbishop of Milan from 1954 to 1963. Sculpted by Floriano Bodini, it reinterprets the dynamism and exuberance of Gothic and Mannerism prevailing in the cathedral in a contemporary key, with a modeled detail of Carrara marble that makes it similar to molded wax.

In the second bay is the altar of the Virgin of Help, with a repainted fifteenth-century fresco. The sepulchral stone of Niccolò and Francesco Piccinino, captains of fortune of Filippo Maria Visconti, is surmounted by the large corbel with the full-length statue of the Monument to Pope Martino V, a valuable monument of late Gothic sculpture by Jacopino da Tradate. The frame and corbel, as well as the pope's rich drapery, represent a typical example of the decorative taste of the last Gothic phase. It was sculpted in 1424 on commission from Filippo Maria Visconti, to commemorate the pope who consecrated the cathedral on 6 October 1418.

This is followed by the Monument to Cardinal Marino Ascanio Caracciolo, governor of Milan who died in 1538, a Mannerist work by Agostino Busti known as Bambaia. The cenotaph is characterized by the bright contrast between the black marble of Varenna, of which the newsstand is made, and the whiteness of the statues that decorate it. The architectural structure, made up of a simple entablature supported by Tuscan columns, is sober and unadorned, unlike the previous works by Bambaia which present a rich decoration. The statuary kit includes, in the centre, the full-figure blessing Redeemer, surrounded by St. Paul and St. Peter. On either side, Saint Jerome in his cardinal's robe and Saint Ambrose with the traditional whip. At the center of the lunette is the tondo from which the Virgin and Child emerges, while on the sides are two small Angels. However, the most valuable sculptural work is the recumbent statue of the deceased that surmounts the sarcophagus. The cardinal is represented on a triclinium with classical lines, while he seems to have dozed off while reading the book he holds open on his knees. The governor's face, marked by his wrinkles, appears immersed in sleep and constitutes Bambaia's last masterpiece.

The third bay has a copy of the ancient marble slab of the Chrismon Sancti Ambrosii and a bas-relief with Pietà and two angels by a 14th-century Rhenish master, as well as a standard of the congregation of the Rosary, from the late 16th century, with embroidery and paintings.

In the fourth span, the Monument to San Carlo from 1611 commemorates the consecration of Carlo Borromeo on 20 October 1577, flanked by the herms of Time and Eternity, partly the work of Pietro Daverio, and by two marble slabs with a list of the saints of the which relics are kept in the Cathedral.

The fifth bay has a thirteenth-century Crucifix with dalmatic kept under glass and coming from the Castello Sforzesco in 1449.

The sixth bay has a Crucifix with a virgin and saints, frescoed by a Lombard master at the beginning of the 15th century. On an elaborate corbel in late Mannerist style (by Francesco Brambilla the Elder), is the Monument to Pope Pius IV blessing by Angelo Marini (1567). The monument commemorates the uncle of San Carlo, Angelo Medici di Marignano, whose Medici coat of arms is supported by one of the imaginative angels that decorate the shelf. Another contemporary Lombard fresco is the San Giovanni Battista and Madonna with Child. In the seventh bay is the portal to the north vestry.

 

Apsidal windows

The three huge apsidal windows are the oldest and largest in the cathedral. The two side windows, each with 130 panels, contain Stories from the New Testament and Stories from the Old Testament. They were completely rebuilt over a period of time ranging from 1833 to 1865 by Giovanni Battista Bertini and his sons Pompeo and Giuseppe, then director of the Brera Academy. The central glass window, dedicated to the Vision of the Apocalypse, however, maintains around fifty pieces from the 15th and 16th centuries in the upper part. It was originally commissioned in 1416 to Franceschino Zavattari, Maffiolo da Cremona and Stefano da Pandino. At the end of the fifteenth century Cristoforo de' Mottis and Niccolò da Varallo also took part. It is also called of the "race" or Visconti sun, from the gigantic sun that stands out in the middle, the heraldic symbol, together with the snake, of the Visconti Dukes of Milan.

 

Southern sacristy

The portal of the southern sacristy is an exceptional masterpiece of late Gothic sculpture, perfectly preserved, created by the German stonemason Hans von Fernach, or John of Fernach, at the end of the fourteenth century. The vibrant piece of sculpture develops above the architrave of the door, attributed instead to Giovannino de' Grassi, who decorated it with quadrilobate panels with Heads of Prophets like the portal of the northern sacristy. The decorative sobriety of the portal contrasts sharply with the redundant style of the decorations above.

The work is entirely dedicated to the celebration of Mary. The crowning has the shape of an ogival arch flanked by two pinnacles, and ending in the Crucifixion. The whole composition presents a fervid imagination in the conception and a refined and exuberant richness in the realization. At the base are the reliefs of the Wise Virgins and the Foolish Virgins, the former with the lamps on and the latter with the lamps off, according to the Parable of the ten virgins which is very frequent in medieval iconography. The same freshness characterizes the representation of the episodes of the Life of Mary in the soffits in the arch, alternating with the elaborate crowning. From left: the Annunciation, the Visitation, the Nativity, the Flight into Egypt and the Massacre of the Innocents. On the first level of the composition, a composed Pietà shows a refined graphic elegance in the sinuous lines of the drapery in contrast with the rigid fixity of the body of Christ. In the center of the lunette, a Madonna del Latte is flanked by kneeling Saint John and Saint Andrew. On the cusp, the Madonna della Misericordia is depicted with her arms outstretched to open her large mantle to welcome the faithful. The extrados of the lunette has the traditional Gothic decoration with large curled leaves, or "gattoni".

The inside of the sacristy is lined with 17th century wardrobes. Above the entrance is a Martyrdom of Saint Thecla by Aurelio Luini (1592). The sink has a dossal with a cusp, in whose lunette there is a polylobed medallion with Jesus and the Samaritan woman, by Giovannino de' Grassi (1396). On the left is a niche with a Christ at the column by Cristoforo Solari.

 

Northern sacristy

The northern sacristy represents the exact point from which the construction of the cathedral started, as evidenced by the presence of terracotta decorations, later replaced by marble throughout the rest of the building. In the portal it presents the most ancient work of sculpture of the Duomo, the work of Giacomo da Campione and Giovannino de' Grassi dating back to 1386. The architrave and the splay of the lunette contain elegant quadrilobate panels, from which the Heads of Prophets emerge, which with elegant beards and fanciful headdresses testify to the elaborate taste of international gothic. In the lunette, Christ enthroned is flanked by a Madonna del latte, portrayed in the symbolic gesture of giving milk from her breasts, and by Saint John the Baptist, who exhibits his head on a tray. In the architrave above, the dove of the holy spirit is flanked by four caryatids in the shape of angels, who support a large aedicula with superimposed cusps, flanked by four pinnacles. In the pointed arch in the center of the upper aedicula is the relief with the Glory of Christ. Christ enthroned, blessing, is supported by a group of cherubs inside the flaming mandorla, surrounded by angels and saints. The entire work presents remains of the primitive polychromy.

Inside the sacristy, the floor is by Marco Solari da Carona of 1404-1407. Behind the Baroque cabinets remains a fragment of a Gothic brick arch, which bears witness to the very first construction phase of the Cathedral (1386-mid 1387). One of the gables of the wardrobes is painted by Morazzone with San Carlo and two angels (1618). In a niche there is the statue of the Redeemer by Antonio da Viggiù, while the vault is frescoed by Camillo Procaccini.

 

Excavations

From a narrow staircase in the internal façade one can access the basement where the floor of the fourth century is located, about four meters below the current level of the square. Here are the remains of the baptistery of San Giovanni alle Fonti, built from 378 and completed by 397, in which Saint Ambrose baptized the future Saint Augustine on Easter night in 387. It had an octagonal layout, for a diameter of 19.3 meters, with niches that opened in the walls alternatively semicircular and rectangular. In the center there is still the octagonal font, the oldest that is documented, which however is largely stripped of the original marble decoration.

Other remains pertain to the apses of the basilica of Santa Tecla, a summer cathedral prior to the mid-4th century, demolished in 1461-1462.

 

Cathedral terraces

Through the elevator contained in the east buttress of the north arm of the transept, one can access the terraces of the Cathedral, from which one can enjoy an extraordinary view of the dense embroidery of spiers, flying buttresses (where the rainwater drains are hidden), pinnacles and statues as well as the city.

Near the lift is the Carelli spire, the oldest in the Cathedral, which dates back to 1397-1404 and was built thanks to the legacy of Marco Carelli. It is decorated with statuettes from the first half of the 15th century which recall Burgundian ways. The terminal part has been redone while the statue on the top, depicting Gian Galeazzo Visconti, is a copy of the original by Giorgio Solari, now kept in the Cathedral Museum. Of all the other spiers, only six date from the 15th and 16th centuries and about ten are from the 17th and 18th centuries.

The lantern by Giovanni Antonio Amadeo (1490-24 September 1500) is surmounted on the outside by eight inverted arches which support the main spire, completed in 1769 with a marble structure, which is connected to an iron framework from 1844. Around the lantern there are four gugliotti, designed by Amadeo, who saw only the north-east one built (1507-1518), enriched by coeval statuary today largely replaced by copies; at the base of the spire is the commemorative bas-relief with the effigy of Amadeo. The north-west one was completed by Paolo Cesa Bianchi in 1882-1887, the south-west one by Pietro Pestagalli in 1844-1847 and the south-east one, which also acts as a bell tower, by Giuseppe Vandoni in 1887-1892.

Among the statues, those in the southern part of the falconatura of the façade are singular, dating back to the refurbishment of 1911-1935: they depict the Sports and are an unusual example of statuary from the 1930s.

 

Madonna

Inaugurated on December 30, 1774, the Madonnina del Duomo di Milano is the highest point of the church. The statue was designed by the sculptor Giuseppe Perego and cast by the goldsmith Giuseppe Bini, for a height of 4.16 meters. The inside of the statue preserves a metal skeleton which, degraded in the 1960s, was taken to the museum and replaced by a steel framework.

 

Great Museum of the Milan Cathedral

The Museum, housed inside the Royal Palace on the right side of the Cathedral, houses the Cathedral Treasury, a very rich collection of goldsmith's works of art and masterpieces of art, evidence of 1500 years of history of the Milanese Church, the original specimens of many of the cathedral's finest sculptures, paintings, tapestries, stained glass windows and models that bear witness to the entire history of the cathedral.
