On the south wall of the peristyle was a cult painting. It depicted the Genius holding a cornucopia and patera, pouring a libation onto an altar. Beside the Genius was the camillus who also held a patera. Opposite stood the tibicen and the popa, who led a pig for sacrifice. Only one Lar was preserved when Boyce recorded the painting. A red and yellow serpent coiled around an altar in the lower register of the scene. The painting has disappeared today.
