Bellerophon (pronounced /bəˈlɛrəfən/; Greek: Βελλεροφῶν) or Bellerophontes (Βελλεροφόντης)
is a hero of Greek mythology. He was "the greatest hero and slayer of monsters, alongside of Cadmus and Perseus, before the days of Heracles", and his 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."
While riding the winged Pegasus...he slayed the Chimera...when he arrived in Lycia, the Chimera was truly ferocious, and he could not harm the monster even while riding on Pegasus. He felt the heat of the breath the Chimera expelled, and was struck with an idea. He got a large block of lead and mounted it on his spear. Then he flew head-on towards the Chimera, holding out the spear as far as he could. Before he broke off his attack, he managed to lodge the block of lead inside the Chimera's throat. The beast's fire-breath melted the lead, and blocked its air passage. The Chimera suffocated, and Bellerophon returned victorious to King Iobates
