PEPARETHUS or PEPARETHOS

A son of Dionysus by Ariadne.

"And at his suggestion she gave Theseus a clue when he went in; Theseus fastened it to the door, and, drawing it after him, entered in. And having found the Minotaur in the last part of the labyrinth, he killed him by smiting him with his fists; and drawing the clue after him made his way out again. And by night he arrived with Ariadne and the children at Naxos. There Dionysus fell in love with Ariadne and carried her off; and having brought her to Lemnos he enjoyed her, and begat Thoas, Staphylus, Oenopion, and Peparethus." (Apollodorus, Library and Epitome)

Later writers, such as Diodorus Siculus, identified the island of Dia with Naxos.
