A mythical hero, son of Glaucus and grandson of Sisyphus; having unwittingly caused the death of his brother, withdrew from his country and sought retreat with Proetus, king of Argos, who, becoming jealous of his guest, but not willing to violate the laws of hospitality, had him sent to Iobates, his son-in-law, king of Lycia, with instructions to put him to death. Iobates, in consequence, imposed upon him the task of slaying the Chimaera, persuaded that this monster would be the death of him. Bellerophon, mounted on Pegasus, the winged horse given him by Pallas, slew the monster, and on his return received the daughter of Iobates to wife.
