House of P. Casca Longus is located on Via Dell 'Abbondanza. The house was first excavated in 1927 and got its name from the inscription on the leg of a marble table found in the garden of the neighboring house in Insula 6, 8-9. Considering that the table was too beautiful for such a modest building, the first archaeologists thought in this way established a very fragile connection with P. Casca Longus.
The lobby (a) opens on the south side of Via del Abbondanza
(pictured above). It is decorated in the third style with yellow
central panels surrounded by red side panels over the bottom
decorated with a black frieze. The side panels have images of local
landscapes, and the upper zone consists of a layer of coarse gray
plaster. A corridor leads directly to a large rectangular atrium or
living room (b) with rooms on three sides. In the center of the
atrium is impluvium, an indoor pool, the bottom of which is
decorated with colored pieces of marble. The pool is located
directly under the hole in the roof. During the rain, the water from
the roof merged into this small pool. Usually this water was not
drunk, but after the earthquake of 62 years, the water supply system
was damaged, thus pools began to be used for drinking.
On the
east and west sides of the atrium there are a number of rooms (c).
Two rooms on the east side are decorated in the third style. The
decoration of the smaller of the two rooms in the northeast corner,
consists of a central panel with floating swans in the side walls
against a black background. Decoration in a larger room consists of
flowers and floating figures on a purple background. The room on the
west side is also decorated in the third style, the decoration in
both consists of red panels on a black background above the bottom
black frieze.
The last of the rooms located around the atrium
is a small storeroom (d) in the south-east corner and in the center
of the south side - the owner's office (e). The office is fully open
on the north and south sides, providing a wide passage from the
atrium to the garden. The room was not decorated during the
eruption.
