Isis seems to have appealed to women. Tibullus complains of Delia's devotion to her, and her ritual. There were baths and purifications; the worshippers wore linen garments and slept alone. Whole nights were spent sitting in the temple amid the rattling of the sistrum. Morning and evening the votary with flowing hair recited the praises of the goddess.[78] Isis could make her voice heard on occasion, or her snake of silver would be seen to move its head, and penance was required to avert her anger. She might bid her worshippers to stand in the Tiber in the winter, or to crawl, naked and trembling, with blood-stained knees, round the Campus Martius--the Iseum stood in the Campus as it was forbidden within the City Walls; or to fetch water from Egypt to sprinkle in the Roman shrine. They were high honours indeed that Anubis claimed, as, surrounded by shaven priests in linen garments, he scoured the city and laughed at the people who beat their breasts as he passed.[79] The "barking" Anubis might be despised by Virgil and others, but the vulgar feared him as the attendant of Isis and Serapis.[80] Isis began to usurp the functions of Juno Lucina, and women in childbed called upon her to deliver them.[81] She gave oracles, which were familiar perhaps even so early as Ennius' day,[82] and men and women slept in the temples of Isis and Serapis, as they did in those of AEsculapius, to obtain in dreams the knowledge they needed to appease the god, or to {23} recover their health, or what not.[83] It is not surprising that the shrines of Isis are mentioned by Ovid and Juvenal as the resorts of loose women.[84] The devotion of the women is proved by the inscriptions which are found recording their offerings to Isis. One woman, a Spaniard, may be taken as an illustration. In honour of her daughter she dedicated a silver statue to Isis, and she set forth how the goddess wore a diadem composed of one big pearl, six little pearls, emeralds, rubies, and jacinths; earrings of emeralds and pearls; a necklace of thirty-six pearls and eighteen emeralds (with two for clasps); bracelets on her arms and legs; rings on her fingers; and emeralds on her sandals.[85] There is evidence to show that the Madonna in Southern Italy is really Isis re-named. Isis, like the Madonna, was painted and sculptured with a child in her arms (Horus, Harpocrates). Their functions coincide as closely as this inscription proves that their offerings do.[86] Die Mutter Gottes zu Kevlaar Traegt heut' ihr bestes Kleid.
