Catacombe di Domitilla, Rome

Domitilla's catacombs are part of a vast funereal complex, a necropolis that contains monuments from the 1st century BC. Santa Petronilla and the martyrs Nereo and Achilleo are buried in this area. The bodies of the two martyrs are in the underground basilica, whose entrance bears an inscription in their honor dictated by Pope Damaso. In one of the numerous cubicles there is a painting of matron Veneranda entering paradise accompanied by the martyr Petronilla. This is probably the first document that refers to Petronilla as a martyr; indeed, it dates from the first half of the 4th Century. Part of the catacombs is reserved for the tombs of children, and there are images of Love and Psyche depicted as children surrounded by floral decorations.
