House of the Carbonised Furniture (Casa del Mobilio Carbonizzato) (Herculaneum)

The House of the Carbonised Furniture, known in Italian as Casa del Mobilio Carbonizzato, is a remarkably preserved ancient Roman residence located in the archaeological site of Herculaneum (modern Ercolano, Italy). Situated at Insula V.5 on the southern end of Cardo IV Superiore, one of the town's main north-south streets, this house exemplifies the urban domestic architecture of the 1st century CE. Herculaneum, like nearby Pompeii, was catastrophically buried during the eruption of Mount Vesuvius in 79 CE. However, Herculaneum's unique preservation stems from being entombed under thick layers of pyroclastic flows—hot, dense mixtures of ash, pumice, and gas that reached temperatures of 300–500°C. This process carbonized organic materials such as wood, rather than fully incinerating them as occurred in Pompeii, leading to the exceptional survival of wooden artifacts that give the house its name. The house is one of the oldest structures in Herculaneum, with origins tracing back to the pre-Roman Samnite period (circa 4th–1st century BCE), and it underwent significant renovations during the reign of Emperor Claudius (41–54 CE), including repairs after the earthquake of 62 CE. It is believed to have belonged to Marcus Pilius Primigenius Granianus, based on inscriptions found on artifacts, and it highlights how mid-1st-century urban homes adapted to sloping terrain and multi-story living.
The house's significance lies not only in its architectural insights but also in its role as a window into Roman daily life, furniture craftsmanship, and the devastating yet preservative effects of volcanic activity. As part of the Parco Archeologico di Ercolano, it remains open to visitors, though upper levels may be restricted for conservation reasons. Modern studies continue to focus on the challenges of preserving these carbonized organics, which are vulnerable to moisture and decay.

Excavation History

Exploration of the site began in the 18th century with Bourbon-era tunneling, which haphazardly uncovered parts of Herculaneum but often damaged or removed artifacts. Systematic open-air excavations ramped up in the 1920s–1930s under the direction of archaeologist Amedeo Maiuri, who exposed much of Insula V, including this house in 1932–33. Maiuri's work documented the carbonized furniture in situ, providing invaluable records. In the 20th and 21st centuries, further conservation and analysis have employed advanced techniques, such as identifying wood species used in the furniture (e.g., oak, ash, and others) through microscopic examination. The discoveries here have influenced broader understandings of Roman woodworking, with items like tables and cradles serving as rare surviving examples of everyday Roman furnishings.

 

Architectural Layout and Room Descriptions

Occupying a rectangular plot of approximately 250–300 square meters on sloping ground, the house features a multi-story design typical of Herculaneum's dense urban fabric. Its façade on Cardo IV is constructed in opus reticulatum (diamond-patterned masonry) with visible beam holes indicating upper floors and balconies. The layout merges Samnite and Roman elements, emphasizing axial symmetry from the entrance through the atrium to the tablinum and garden. Unlike many Pompeian homes, it lacks a traditional impluvium (rainwater basin) in the atrium, instead relying on an upper gallery with columns for light and air circulation. Drainage systems connect to cisterns, and the house includes sophisticated features like carbonized wooden ceilings and timber-framed walls (opus craticium) added for post-earthquake stability. Stairs near the entrance and kitchen provide access to upper private quarters.
Key ground-floor rooms, based on standard archaeological numbering (e.g., from plans by Pesando and Guidobaldi), include:

Entrance Hall (Vestibulum, labeled 'a'): A narrow corridor from the street leading directly into the atrium. It features remnants of simple Third Style frescoes, characterized by intricate panel designs.
Atrium (labeled 'b'): The central hall, serving as the home's hub. Supported by an upper gallery with columns, it connects to surrounding rooms. Decorations are mostly eroded, surviving only as plaster fragments in Third Style.
Tablinum (labeled 'c'): The owner's office and reception room, east of the atrium with windows overlooking the garden. It boasts Third Style frescoes in red and yellow panels with floating figures above a red border, paired with a white mosaic floor edged in black.
Garden (Viridarium, labeled 'd'): A small rectangular outdoor space to the east, providing natural light to adjacent areas. No major preserved features, but it enhanced ventilation and aesthetics.
Courtyard (labeled 'e'): South of the entrance, featuring an impluvium pool and a prominent lararium (household shrine) with stucco bas-reliefs, paintings, and two columns. Decorated in Fourth Style with illusory architectural elements.
Cubiculum (Bedroom, possibly part of 'e'): Adjacent to the courtyard, with Fourth Style frescoes including architectural motifs, a rooster panel, and still-life scenes.
Kitchen (Culina, labeled 'g'): North of the atrium, accessed via a low doorway (under 1.5 meters high). Utilitarian space with stairs to the upper floor; no notable decorations.
Triclinium (Dining Room, labeled 'h'): North of the courtyard, with three windows for light. Features Fourth Style frescoes: red panels with medallions and mythological scenes above a black border. This room housed significant carbonized furniture.

Upper floors, now partially inaccessible, contained private rooms with preserved carbonized wooden ceilings featuring geometric inlays, reliefs, and traces of gilding in red, white, and blue.

Decorations and Artistic Features

The house's interior decorations reflect evolving Roman tastes, spanning Third Style (circa 15 BCE–45 CE), with its delicate, flat panels and subtle ornamentation, and Fourth Style (circa 45–79 CE), known for creating illusions of depth through architecture, mythology, and vibrant colors like red, yellow, and black. Frescoes often include borders, floating figures, medallions, and scenes such as roosters or still lifes. Floors are simple white mosaics with black borders, while the lararium in the courtyard stands out with its stucco reliefs and painted details, depicting a small Corinthian temple form (about 100x100 cm). Ceiling panels, some painted (74x61 cm) with traces of expensive Egyptian blue pigment, add to the opulence.

 

Artifacts and Carbonized Furniture

The house's defining feature is its trove of carbonized wooden furniture, preserved through the volcanic heat that charred but did not destroy the organics. These items provide rare insights into Roman craftsmanship, using techniques like mortise-and-tenon joints and inlays (occasionally ivory or bone, but primarily wood). Notable pieces include:

A dining couch (lectus triclinaris) from the triclinium, designed for reclining during meals.
A rocking cradle (49x81 cm, made of oak and ash), discovered in an upper room and inscribed with the possible owner's name, Marcus Pilius Primigenius Granianus.
A wooden cupboard and a stool (42x49 cm) with an inlaid star motif, showcasing varied woods.
The lararium shrine itself, carbonized and mobile.
Other items like a carved purse (13.3x4.7 cm) and table fragments, including one from this house studied for its wood composition.

These artifacts are often displayed in museums or on-site replicas, as the originals require controlled environments to prevent deterioration.

 

Notable Features and Historical Significance

Beyond its furniture, the house features low doorways, advanced drainage, and evidence of multi-family or extended household use on upper floors. It underscores Herculaneum's differences from Pompeii: better-preserved organics due to the mud-like pyroclastic material, offering glimpses into textiles, food, and woodwork rarely seen elsewhere. Historically, it reflects social mobility in Roman society, with renovations indicating prosperity. Today, it contributes to ongoing research on ancient materials science and serves as a poignant reminder of the Vesuvian disaster's dual role in destruction and preservation.
