Essentially, the phallic symbol was anciently viewed as an amatory agent, a generative stimulant, in as much as the phallus was cosmically the source of all being. Therefore offerings were made to the phallus in sacrificial rituals, just as to any other potent deity from whom privileges and favors were sought. Libations of milk were a normal form of offering to Priapus. Women, anxious to become mothers, stood reverently and suppliantly in puris naturalibus before the all-potent phalli, and in a further urgent procedure, performed the act of erotic consummation with the aid of the lingam figure itself. For the phallus, in a pose of lubricity, was the final appeal, the ultimate resort, of the pleading, awed, reverential mortal.
Among cities where the generative force symbolized by the phallus was held in deep veneration, were Orneae, Cyllene, and Colophon. Under the later impact of Christianity, however, the phallic cult diminished in its influence and extent, or was re-directed into other channels. In one specific direction, the cult merged into the Orphic mysteries.
Erotic awareness never went further than in the case of a city in Troas named Priapus, on account of its consecration to the cult of the phallus. There were other cities too, according to the testimony of Pliny the Elder, that were named Priapus for identical reasons. In the Ceramic Gulf there was an island named Priaponese: and an island in the Aegean Sea called Priapus.
A notorious incident in Greek history involved the nocturnal mutilation of hermae, in 415 B.C. Hermae were bronze or marble pillars surmounted by a head and a phallus. These marble figures appeared in the streets and squares of Athens and other Greek cities.
Suspicion for the defilement and desecration of the hermae fell upon the brilliant but wayward Athenian general and statesman Alcibiades and his companions. As a result, Alcibiades was condemned to banishment.
