In a recently published fragment of an elegiac poem about gods who loved youths mention is made of stories about Apollon and Hyakinthos, Dionysos and Ampelos, and Herakles and Hylas. In the third tale Hylas is called a Thracian–⊝ρἡïκος) Ύλα. However, Hylas was a Dryopian by birth, because his father Theiodamas was a Dryopian of Mount Oita. There is no sign that the Dryopians were of Thracian stock. The difficulty has prompted the comment that the poet either used a version of the Hylas-myth unknown to us or was deficient in knowledge of Greek geography.

Some Dryopians migrated to the Argolid. Their presence near Argos may be recalled by Hyginus in the words Hylas . . . ex Oechalia, alii aiunt ex Argis, but, as the editors of the elegiacs insist, ‘neither location justifies “Thracian”; nor does his disappearance which A <pollonius> R<hodius> places near Cius in Mysia’.
