in Greek mythology, was a monster who occupied a cave on Parnassus and devastated the land around. By the command of the oracle a youth was to be sacrificed to him, and the task fell by lot upon Alcyoneus, son of Diomus, who, adorned with a garland, was brought to the cave; but, charmed with the beauty and youth of the victim, Eurybatus took the garland, went into the cave, fought the monster, and hurled it down a precipice.
