Chimera

It was a three-headed monster, which ravaged the countryside of Lycia in Anatolia. It was a bizarre fire-breathing creature with the body and head of a lion, a goat’s head rising from its back, the udders of a goat, and a serpent for a tail.

The hero Bellerophon was commanded by King Iobates to slay the beast. He rode into battle on the back of the winged horse Pegasus and drove a lead-tipped lance into its flaming throat, choking the beast on molten metal.

Parents: Echidna and Typhon
