On the wall with niches that characterizes the paved road behind the Basilica of Maxentius (so-called
intercapedine) there is a wall covering made with painted plaster and concretions. The limited remains,
concentrated in the sector in which the road bends at right angles, allow you to reconstruct a geometric
decorative pattern with colored bands inside two niches with a tympanum pattern. Unusual and particularly
interesting is the technique adopted for the realization that sees the insertion of pumice stones soaked
in the same color used for the laying of the bottom, a solution that currently finds sporadic examples mostly
attributable to environments that simulate caves (well known as “finta grotta”)
