“There he was sent to fetch water, and was ravished by Nymphs on account of his beauty. But nobody saw anything, and no traces of him were ever found. According to what has been reported, when this happened, the Argonaut Polyphemus heard Hylas cry out. They say that he then took his sword believing that the handsome young man had been attacked by robbers, and went searching for him. Polyphemus did not find Hylas, but instead fell in with Heracles, and told him that something had happened to their comrade.
“Heracles and Polyphemus started then a fruitless search, for Hylas was never seen again. And as they were busy searching for Hylas, they were themselves lost for the rest of the Argonauts, and the ship put to sea.”
