Prosymnus (Ancient Greek: Πρόσυμνος) (also known as Polymnus (Πόλυμνος) and Hypolipnus) was, in Greek mythology, a shepherd living near the reputedly bottomless Alcyonian Lake, hazardous to swimmers, which lay in the Argolid, on the coast of the Gulf of Argos, near the prehistoric site of Lerna.
[2] He carved a piece of fig wood into the shape of a phallus and simulated sex with the shepherd.
[3] This story is not told in full by any of the usual sources of Greek mythological tales, though several of them hint at it.
It is reconstructed on the basis of statements by Christian authors; these have to be treated with reserve because their aim is to discredit pagan mythology.
[4] Annual nocturnal rites took place at the Alcyonian Lake in classical times; Pausanias refuses to describe them.
