Bellerophon,
in Greek mythology, the son of Glaucus, king of Corinth; he was the hero who tamed the winged horse Pegasus with the aid of a bridle given him by the goddess Athena. Falling in love with the wife of King Proetus of Argos, Bellerophon aroused the jealously of Proetus, who sent him to his father-in-law Iobates, king of Lycia, with a message requesting that the bearer be slain. The king, having entertained Bellerophon before he read the message, was afraid to anger the god Zeus by carrying out a request that would break the traditional bond between host and guest. Instead of killing Bellerophon, he asked him to kill the Chimera, a fire-breathing monster, which the hero did with the help of Pegasus. He also defeated the Solymi and the Amazons, two warrior tribes. Iobates was impressed by Bellerophon's superhuman courage and married him to his daughter. After a time of prosperity, Bellerophon defied the gods by trying to ride Pegasus up to Olympus, but, thrown to the earth by the horse, he wandered in misery until he died.
