By hetaerism Morgan designates sexual intercourse of men with unmarried women outside of the monogamous family, flourishing, as is well known, during the whole period of civilization in many different forms and tending more and more to open prostitution. This hetaerism is directly derived from group marriage, from the sacrificial surrender of women for the purpose of obtaining the right to chastity. The surrender for money was at first a religious act; it took place in the temple of the goddess of love and the money flowed originally into the treasury of the temple. The hierodulae of Anaitis in Armenia, of Aphrodite in Corinth and the religious dancing girls of India attached to the temples, the so-called bajaderes (derived from the Portuguese "bailadera," dancing girl), were the first prostitutes. The surrender, originally the duty of every woman, was later on practiced by these priestesses alone in representation of all others. Among other nations, hetaerism is derived from the sexual freedom permitted to girls before marriage--also a survival of the group marriage, only transmitted by another route. With the rise of different property relations, in the higher stage of barbarism, wage labor appears sporadically by the side of slavery, and at the same time its unavoidable companion, professional prostitution of free women by the side of the forced surrender of female slaves. It is the heirloom bequeathed by group marriage to civilization, a gift as ambiguous as everything else produced by ambiguous, double-faced, schismatic and contradictory civilization. Here monogamy, there hetaerism and its most extreme form, prostitution. Hetaerism is as much a social institution as all others. It continues the old sexual freedom--for the benefit of the men. In reality not only permitted, but also assiduously practised by the ruling class, it is denounced only nominally. Still in practice this denunciation strikes by no means the men who indulge in it, but only the women. These are ostracised and cast out by society, in order to proclaim once more the fundamental law of unconditional male supremacy over the female sex.
