Within this building was a cult painting. The scene depicted an altar in the centre with Vesta standing on the right holding a sceptre and pouring a libation on the altar. At her side stood a donkey. On the left of the altar was Bacchus, holding a bunch of grapes and a thyrsus. On each side of this group stood a Lar, holding rhyton and patera. Below two serpents met at an altar. The exact location of this cult painting is unknown as it is no longer preserved.
