See, e.g., the chapter on ritual in Gérard-Varet's interesting book, L'Ignorance et l'Irreflexion, 1899, for a popular account of this and allied primitive conceptions.
Jastrow, Religion of Babylonia, especially pp. 485, 571; regarding the priestesses, Jastrow remarks: "Among many nations, the mysterious aspects of woman's fertility lead to rites that, by a perversion of their original import, appear to be obscene. The prostitutes were priestesses attached to the Ishtar cult, and who took part in ceremonies intended to symbolize fertility." Whether there is any significance in the fact that the first two months of the Babylonian year (roughly corresponding to our March and April), when we should expect births to be at a maximum, were dedicated to Ea and Bel, who, according to varying legends, were the creators of man, and that New Year's Day was the festival of Bau, regarded as the mother of mankind, I cannot say, but the suggestion may be put forward.

Grimm, Teutonic Mythology, p. 1465. In England, the November, bonfires have become merged into the Guy Fawkes celebrations. In the East, the great primitive autumn festivals seem to have fallen somewhat earlier. In Babylonia, the seventh month (roughly corresponding to September) was specially sacred, though nothing is known of its festivals, and this also was the sacred festival month of the Hebrews, and originally of the Arabs. In Europe, among the southern Slavs, the Reigen, or Kolo—wild dances by girls, adorned with flowers, and with skirts girt high, followed by sexual intercourse—take place in autumn, during the nights following harvest time.
