56 looks like a small altar with a niche.
The grave has been removed from its original place, the right wall
of tomb 55, to the back-wall of the same tomb.
The niche, standing on a brick base, has been formed by two columns
with capitals of tufa on which a triangular tympanum rests. In the
niche we see depicted a double,
half open door. From the back a man, unquestionably
the deceased, is entering. His head is missing. This scene is well-known
from archaic times: leaving this earthly life through the door to
eternity. The grave has the following inscription:
Taurio has made (this monument) for his
very pious son, Sabinus.
