In Greek mythology, the Chimera was a fearsome, fire-breathing monster with a lion's head, a goat's body, and a dragon's tail. She terrorized the Lycians until felled by Pegasus, the winged horse. The Chimeric beast lives on in people's imaginations, her name becoming synonymous with grotesque monsters combining bodily parts from different beings. It also lives on in science.
