accused Isis's cult of encouraging promiscuity among women. Jaime Alvar suggests the cult attracted male suspicion simply because it gave women a venue to act outside their husbands' control. Priests of Isis were known for their distinctive shaven heads and white linen clothes, both characteristics drawn from Egyptian priesthoods and their requirements of ritual purity. A temple of Isis could include several ranks of priests, as well as various cultic associations and specialized duties for lay devotees. There is no evidence of a hierarchy overseeing multiple temples, and each temple may well have functioned independently of the others. Temples and daily rites Temples to Egyptian deities outside Egypt, such as the Red Basilica in Pergamon, the Temple of Isis at Pompeii, or the Iseum Campense in Rome, were built in a largely Greco-Roman style but, like Egyptian temples, were surrounded by large courts enclosed by walls. They were decorated with Egyptian-themed artwork, sometimes including antiquities imported from Egypt. Their layout was more elaborate than that of traditional Roman temples and included rooms for housing priests and for various ritual functions, with a cult statue of the goddess in a secluded sanctuary. Unlike Egyptian cult images, Isis's Hellenistic and Roman statues were life-size or larger. The daily ritual still entailed dressing the statue in elaborate clothes each morning and offering it libations, but in contrast with Egyptian tradition, the priests allowed ordinary devotees of Isis to see the cult statue during the morning ritual, pray to it directly, and sing hymns before it. Another object of veneration in these temples was water, which was treated as a symbol of the waters of the Nile. Isis temples built in Hellenistic times often included underground cisterns that stored this sacred water, raising and lowering the water level in imitation of the Nile flood. Many Roman temples instead used a pitcher of water that was worshipped as a cult image or manifestation of Osiris.

Isis and other Egyptian deities were found in lararia in Italy from the late first century BCE to the beginning of the fourth century CE. The cult asked both ritual and moral purity of its devotees, periodically requiring ritual baths or days-long periods of sexual abstinence. Isiacs sometimes displayed their piety
