Bellerophon (βελλεροφῶν) or Bellerophontes (βελλεροφόντης) was a hero of Greek mythology, "the greatest hero an slayer of monsters, alongside of Kadmos and Perseus, before the days of Heracles", whose greatest feat was killing the Chimera, a monster that Homer depicted with a lion's head, a goat's body, and a serpent's tail: "her breath came out in terrible blasts of burning flame".
