a son of Dionysus and Aphrodite. Aphrodite, it is said, had yielded to the embraces of Dionysus, but during his expedition to India, she became faithless to him, and lived with Adonis. On Dionysus return from India, she indeed went to meet him, but soon left him again, and went to Lampsacus on the Hellespont, to give birth to the child of the god. But Hera, dissatisfied with her conduct, touched her, and, by her magic power, caused Aphrodite to give birth to a child of extreme ugliness, and with unusually large genitals. This child was Priapus.

TO PRIAPUS OF THE SHORE
Priapus of the seashore, the trawlers lay before thee these gifts by the grace of thine aid from the promontory, having imprisoned a tunny shoal in their nets of spun hemp in the green sea-entrances: a beechen cup and a rude stool of heath and a glass cup holding wine, that thou mayest rest thy foot weary and cramped with dancing while thou chasest away the dry thirst.
According to others, however, Priapus was a son of Dionysus and a Naiad or Chione, and gave his name to the town of Priapus, while others again describe him as a son of Adonis, by Aphrodite, as a son of Hermes, or as the son of a long-eared father, that is, of Pan or a Satyr.
The earliest Greek poets, such as Homer, Hesiod, and others, do not mention this divinity, and Strabo expressly states that it was only in later times that he was honoured with divine worship, and that he was worshipped more especially at Lampsacus on the Hellespont, whence he is sometimes called Hellespontiacus.
We have every reason to believe that he was regarded as the promoter of fertility both of the vegetation and of all animals connected with an agricultural life, and in this capacity he was worshipped as the protector of flocks of sheep and goats, of bees, the vine, all garden-produce, and even of fishing.
Like other divinities presiding over agricultural pursuits, he was believed to be possessed of prophetic powers, and is sometimes mentioned in the plural. As Priapus had many attributes in common with other gods of fertility, the Orphics identified him with their mystic Dionysus, Hermes, Helios, etc.
The Attic legends connect Priapus with such sensual and licentious beings as Conisalus, Orthanes, and Tychon. In like manner he was confounded by the Italians with Mutunus or Muttmms, the personification of the fructifying power in nature.
The sacrifices offered to him consisted of the first-fruits of gardens, vineyards, and fields, of milk, honey, cakes, rams, asses, and fishes.
He was represented in carved images, mostly in the form of hermae, with very large genitals, carrying fruit in his garment, and either a sickle or cornucopia in his hand. The hermae of Priapus in Italy, like those of other rustic divinities, were usually painted red, whence the god is called ruber or rubicundus.
