On the west wall of the bakery was a cult painting. Now disappeared, a description survives showing that the scene comprised a sacrificial scene of the Genius and assistants grouped around an altar, with a Lar on each side. According to Mazois, the figure on the left was not a Lar but the goddess Fornax, also suggesing that it was Vesta depicted in the centre rather than a Genius. In the lower register, two serpents meet at an altar. On each side of the scene were panels of a bird. A niche was present below the painting but it is uncertain if this was used as part of the cult space. The painting does not survive today.
