 The walls were made of soluble sand- and marble-dust plaster, which meant that paint could be applied anytime after the final layer of plaster was applied as long as the plaster remained slightly damp.The surviving frescoes come from four cubicula along the villa’s southern hallway around the villa’s central peristyle, where social and business activities occurred.The paintings are from cubiculum 15, 16, and 19, also known as the Black Room, the Red Room, and the Mythological Room, respectively, for the paintings that were in those specific rooms.
