GLAUCUS, son of Hippolochus, and grandson of Bellerophon, was a Lycian prince, who assisted Priam in the Trojan war. When he and Diomedes, to whom he was bound by ties of hospitality, recognised each other in battle, they desisted from the contest, and exchanged arms. Glaucus was afterwards slain by Ajax, but his body was taken back to Lycia.
