The Egyptian god Isis was introduced into the Roman Pantheon early on. Photo: Wall-painting from Herculaneum, showing a scene of Isis-worship. Foreground: a priest rekindles the flame at the altar with a bellows. Right and left of him: three others, with a fourth shown sitting and playing a flute. Background: The temple court. A priest, holding a wand, conducts the worshippers, divided into two groups, before the temple stair. At the top of it is the high priest, emerging from the door: his presence is announced by the sistra held by two other priests. Napoli, Museo Archeologico Nazionale 8924.
