In intimate connection with the mother-right, after it had ceased to be a ruling social principle, stood certain customs, which modern writers, ignorant of their meaning, designate as "prostitution." In Babylon, it was a religious duty with the maid, who had reached puberty, to appear once in the temple of Mylitta in order to offer her maidenhood as a sacrifice, by surrendering herself to some man. Similarly happened in the Serapeum of Memphis; in Armenia, in honor of the goddess Anaitis; in Cyprus; in Tyrus and Sidon, in honor of Astarte or Aphrodite. The festivals of Isis among the Egyptians served similar customs. This sacrifice of virginity was demanded in order to atone with the goddess for the exclusive surrender of woman to one man in marriage:--"Not that she may wilt in the arms of a single man is woman arrayed by nature with all the charms at its command."[14] The continued favor of the goddess had to be purchased by the sacrifice of virginity to a stranger. It was likewise in line with the old idea that the Lybian maids earned their dower by prostituting their bodies. In accord with the mother-right, these women were sexually free during their unmarried status; and the men saw so little objection in these pickings, that those were taken by them for wives who had been most in demand. It was thus also among the Thracians, in the days of Herodotus: "They do not watch the maidens, but leave them full freedom to associate with whom they please. The women, however, they watch strictly. They buy them from their parents for large sums." Celebrated were the Hierodulae of the temple of Aphrodite at Corinth, where always more than one thousand maidens were gathered, and constituted a chief point of attraction for the men of Greece. Of the daughter of King Cheops of Egypt, the legend relates that she had a pyramid built out of the proceeds of prostitution of her charms.
