Hȳlas in Greek myth, son of the king of the Dryopēs. Heraclēs, having killed the father, carried off the son to accompany him on the expedition of the Argonauts. When the Argo touched at Cios on the coast of Mysia (Heracles having broken his oar), Hylas was sent for water. The water-nymphs, falling in love with him, drew him into the spring and he was lost. The Argonauts went on their way, but Heracles remained to look for him. The Mysians held a ritual search for him every year, in obedience to Heracles' orders, even in Hellenistic times.
