One of the earliest instances of multiple incest occurs in Book 10 of Homer’s _Odyssey_, in which Odysseus describes his visit to Aeolus. Aeolus has a family of six daughters and six sons, and he has given his daughters in marriage to his own sons. * * * * * In Greece the Aphrodision, and in Rome the Venereum, were the private bordellos that were not used by the general indiscriminate public. * * * * * Both in antiquity and in later ages the public baths, with both sexes in nude contacts in the _balnea mixta_, were a direct amatory stimulant. As further provocatives, there was, in particular cases, bathing in asses’ milk, in essences of myrtle and lavender, in rose water, in almond paste and in honey water, and also in champagne. * * * * * In Greece, the phallus was so pervasive as a genesiac symbol in every phase of daily life, that there were loaves baked in phallic form. These loaves were known, for another erotic reason, as olisbokolices. * * * * * Drillopotae were glass vessels in phallic form. They were used, in ancient Rome, as drinking cups: and thus were an added erotic reminder at banquets and similar gatherings. * * * * * In Roman antiquity the color yellow was associated with prostitutes, and was a symbol of their profession. Yellow still retained this significance in the Central European countries in later ages. In Tsarist Russia, the yellow ticket was the official prostitute’s occupational token. Alexander Kuprin’s _Yama the Pit_ describes the situation in a vivid and grim narrative. * * * * * Figurae Veneris is a Latin expression meaning _positions of Venus_. This phrase refers to the range of sexual positions. The Greeks were familiar with some seventy such permutations and manipulations. There were the symplegma and the catena, which involved more than two partners, and the dodekamechanon. Hesychius the Greek lexicographer, Philaenis, and, among the Romans, the poet Martial mention these contortions. In the Middle Ages, the licentious poet Pietro Aretino produced a poetic commentary on the entire extent of erotic possibilities. Among periapts and amulets that were credited with promoting erotic activity were charms in the shape of an extended hand, a wild boar, the head of a bull, astrological signs; magic formulas too, inscribed on various objects; the crux ansata, and genitalia. * * * * *
