In Greek mythology the Chimera or a Chimaera was of the offspring of a typhon and Echida.
Descriptions vary. Some say it had the body of a goat, the hind quarters of a snake or a dragon and the head of a lion though others say it had heads of both the goat and lion with a snake’s tail. All descriptions however agree that it breathed fire from one of more of its heads. It was finally defeated by Bellerophon with Pegasus
the winged horse at the command of King Ipbates of Lycia. There are varying descriptions of its death. Some say merely that Bellerophon ran it through its sphere.
