On the northern side of an ala, off the atrium, was a blocked-up doorway on which a cult painting was situated. The scene was set on a red background and depicted a blazing tripod with a Genius holding a patera above the tripod. To the left were the tibicen and a Lar on either side of the scene holding a rhyton and patera. At the top of the scene were garlands that hung down either side. In the lower zone was a single serpent. The scene was outlined by a blue border. Holes in the wall indicate the existence of a shelf at the base of the scene which was likely used to hold offerings or statuettes. The painting does not survive today.
