On the north wall of the caupona at VI. Xiv. 28 was a cult painting. This painting depicted a nude Mercury and Bacchus. Bacchus was crowned with grape vines and was leaning on a pillar while holding his thyrsus. In his other hand, which was positioned above his head, Bacchus was holding a vessel (which presumably held wine). Mercury was depicted where his petasos and a cloak holding his caduceus and a pouch. A photograph of the painting shows that the deities were framed by a border and was not lined up or symmetrical with the other paintings on the wall. This perhaps indicates that this painting was added after the room was originally decorated.
