From the Greek meaning "she-goat" the Chimera is a fire-breathing creature that has the body of a goat, the head of a lion and the tail of a serpent. Some sources have represented the Chimera with three heads (the lion's head as the main, then the goat's head sprouted from its back, and the serpent's or Dragonís head on its tail), but the popular myth tells of the single, fire-vomiting head. The very unlikely aspect of the chimera has gradually turned its name into a synonym of a vain dream.
The chimera of Greek myth is the offspring of Echinda and Typhon. It has many other monstrous brothers and sisters.
