Mosaic

Parts of the floor of the back room have been preserved. The northern two-thirds of the floor of the front room have been preserved. The room is bordered on the east by a line of white marble, slightly to the west of the axis of the central column.

The floor of the front room shows at least three phases. The oldest phase consists of small, white tesserae with a large black frame, nine tesserae wide. In the north-east part is a small leaf. The central and south-west part were restored with white tesserae. In the north-east part of this stretch are the remains of a small, curved object. In the central part are a depiction, a text, and below that two leaves. The west one is very large. On NADIS inv. nr. 645 it is shown further to the south-west and turned 90 degrees. It seems to have been replaced in the wrong position after restoration. Finally, the south-east part was restored with white tesserae. The frame, the depiction, and the text are not in the centre of the room, but moved to the west.

The text is in a tabula ansata with solid black ansae (h. of letters 0.13). It was restored after the publication of the supplement of CIL XIV, and before Becatti wrote. It was apparently done from memory, and the text was altered.

Today: S(leaf)(space)(leaf)F(space)C.
Finelli: (leaf)S(leaf)C(leaf)F.
Paribeni: S(leaf)C(leaf)F.
Wickert: S(leaf)C(leaf)F////, remarking that after the F there is only space for a leaf or one letter.
Becatti: suggests a leaf instead of the C at the end, implicitly accepting the space between the F and the misplaced C.

Combining Wickert and Becatti the text must have been: S(leaf)C(leaf)F(leaf). The current tabula was made too wide by the restorers.

As solution for the abbreviation S(tatio) C(orporis) F(rumentariorum) has been suggested, with F(eliciter) as an alternative. This explanation causes problems, because what is the corpus frumentariorum? We expect something in between, such as mercatorum. For a discussion see the section "The auxiliary grain fleet of Commodus".

Suggested reading:

S(tatio) C(lassis) F(rumentariae)

In the south-east corner of the front room the monogram PE was read (with ligature), crossed by an oblique line attached to a leaf (h. of letters 0.20). This part of the floor is lost. According to Guarducci it stands for the name of the apostle Peter.[1]

Suggested reading:

PE(trus)

Above the text two grain measures flank yet another leaf. The left measure is a bit larger than the right one. There is a rutellum above the right one, not above the left one. The tabula was (before the restoration) mostly below the left measure.

Becatti
Grain measures and leaves. Due moggi neri cilindrici senza anse, su tre piedi rettangolari, con due linee bianche che indicano le cerchiature. Sopra a quello di destra è una rasiera rettangolare nera, orizzontale. Fra i due moggi è una foglia di edera nera. Sotto la tabella iscritta è una grande foglia di edera orizzontale, con viticci e gambo, sotto una minore.

Masonry

The rear wall of the back room is of opus latericium. At the east end is a small pier of opus latericium. Against it the corner was set of a small room in statio 37 (opus latericium). An alcove was created by the corner of a room behind the room to the north of statio 39. The walls of this corner are of opus reticulatum, reinforced with oblong tufa blocks. The remainder of the west wall is of opus vittatum mixtum B (four layers preserved). In the passage between the front room and back room is a wall of much restored opus vittatum mixtum B (six layers preserved) with an opening, the sides of which show the core of the wall. According to Gismondi's plan the entire passage was blocked, the model leaves a door on the east side.

Interpretation

See statio 37. For a discussion of the text and the grain measures see the section "The auxiliary grain fleet of Commodus".
