In Greek mythology Priapus or Priapos was described as the son of Aphrodite (the goddess of love) by Dionysus (the wine god). According to legend, Hera cursed him with impotence, ugliness and foul-mindedness while he was still in Aphrodite's womb, in revenge for the Paris having the temerity to judge Aphrodite more beautiful than Hera (the judgement of Paris). According to some version, Aphrodite had an affair with Zeus, so jealous Hera cursed Arisedite to core a deformed son (Priapus).
The other gods refused to allow Priapus to live on Mt Olympus, and threw him down to Earth, leaving him on a hillside. He was eventually found by shepherds and was brought up by them. Priapus joined Pan and the satyrs as a spirit of fertility.Priapus was the god of the bounty of the vegetable garden. He was also honoured as the protector of sheep, goats, bees, the vine, gardens, fruit plants and male genitalia.
Priapus was described to have lustful nature and permanent erected penis. Priapus is marked by his absurdly over sized, permanent erected penis, which gave rise to the medical term priapism.The ass was sacrificed in his honour, probably because the ass symbolized lecherousness and was associated with the god’s sexual potency.
