The definite ways in which professional prostitution may arise are no doubt many.[131] We may assent to the general principle, laid down by Schurtz, that whenever the free union of young people is impeded under conditions in which early marriage is also difficult prostitution must certainly arise. There are, however, different ways in which this principle may take shape. So far as our western civilization is concerned--the civilization, that is to say, which has its cradle in the Mediterranean basin--it would seem that the origin of prostitution is to be found primarily in a religious custom, religion, the great conserver of social traditions, preserving in a transformed shape a primitive freedom that was passing out of general social life.[132] The typical example is that recorded by Herodotus, in the fifth century before Christ, at the temple of Mylitta, the Babylonian Venus, where every woman once in her life had to come and give herself to the first stranger who threw a coin in her lap, in worship of the goddess. The money could not be refused, however small the amount, but it was given as an offertory to the temple, and the woman, having followed the man and thus made oblation to Mylitta, returned home and lived chastely ever afterwards.[133] Very similar customs existed in other parts of Western Asia, in North Africa, in Cyprus and other islands of the Eastern Mediterranean, and also in Greece, where the Temple of Aphrodite on the fort at Corinth possessed over a thousand hierodules, dedicated to the service of the goddess, from time to time, as Strabo states, by those who desired to make thank-offering for mercies vouchsafed to them. Pindar refers to the hospitable young Corinthian women ministrants whose thoughts often turn towards Ourania Aphrodite[134] in whose temple they burned incense; and Athenæus mentions the importance that was attached to the prayers of the Corinthian prostitutes in any national calamity.[135]
