Located on the south wall of the front commercial room was a cult painting. The scene was framed by a stucco aedicula, with a garland at the top. A wreath sat in the centre of the pediment. The scene was divided into two registers. The upper was painted on a white background and bordered by garlands. From left to right were painted representations of Mercury, holding a money pouch and caduceus, a Lar with a rhyton and situla, a Genius, another Lar, and Bacchus with his panther drinking wine from a cup. The Genius was depicted sacrificing over a tripod altar furnished with offerings of fruit and eggs. The lower panel was painted on a dark red background and depicted two serpents with a cylindrical altar with offerings of eggs in between, with green. Three small holes (perhaps for actual garlands to be hung) were present above the painted garlands in the top panel.
