Belleraphon was a hero of ancient Greek mythology.
Belleraphon is the son of Poseidon by Eurynome, wife of King Glaucus of Corinth who was in turn the son of Merope and Sisyphus, founder of Corinth. Belleraphon's grandsons, Glaucus and Sarpedon were heros of the Trojan War.
The Story of Belleraphon
Belleraphon was exiled for the murder of either his brother Deliades or an enemy. He went to the court of King Proetus of Tiryns to be cleansed of the crime and while he was there the King's wife Anteia (or Stheneboea) propositioned him, but Belleraphon refused her. The Queen responded to this rejection by telling her husband that Belleraphon had attempted to rape her.
Proetus flew into a rage but did not want to violate the code of hospitality by killing a guest, which would invoke the ire of the Erinyes. So he asked Belleraphon to deliver a secret message to his father-in-law, King Iobates of Lycia. The message read "Pray remove the bearer of this message from the world. He did attempt to violate my wife, your daughter."
Iobates received Belleraphon in a most hospitable way and feasted him for nine days before asking him his business. When he read the message contained in the sealed tablet, he too was hesitant to violate the code of hospitality by killing a guest, so instead he asked Belleraphon if he would do him a favor and kill the Chimera, a fearsome, fire-breathing beast that lived in the neighboring land of Caria.
Belleraphon went to see the seer Polyeidos for advice and he was told that he would only be able to defeat the Chimera with the aid of another fantastic beast, the Pegasus. In order to tame the Pegasus, Belleraphon must first sleep in the temple of Athene, which he did.
That night, Athene came to him in a dream and placed a golden bridle next to him saying "Do you sleep, prince of the house of Aiolos? Wake up and take this charm for the steed, and show it to your Father, the Tamer of Horses (Poseidon) when you sacrifice to him a white bull." Belleraphon awoke immediately and found the golden bridle beside him. In thanks, he offered sacrifices to both Athene and Poseidon and then he returned to Polyeidos who told him to take the bridle back to Corinth and find the Pegasus drinking from the well of Pirene and sneak up and slip it onto him, which Belleraphon was able to do successfully.
The Slaying of the Chimera
Once the Pagasus had been tamed to his hand, Belleraphon mounted it and flew to the place where the Chimera dwelled. However, even with the help of Pagasus, Belleraphon couldn't get anywhere near the Chimera because of the great heat of his breath.
After a flash of inspiration, Belleraphon mounted a block of lead to the end of his spear and flew toward the Chimera, swooping down and hurling the spear toward the beasts great mouth, he managed to lodge the lead in the beast's throat. The lead melted and the Chimera suffocated and died.
However, when Belleraphon returned to King Iobates, his story was not believed and he was sent on yet another quest.
The Solymi were the traditional enemies of King Iobates people. When Belleraphon returned from defeating Chimera, Iobates decided to send him alone against the entire tribe, certain that even he couldn't handle those odds. But Belleraphon, with the help of Pegasus, wiped them out easily.
The Amazons and the Ambush
When the Solymi tribe didn't prove much of a challenge, Iobates sent Belleraphon against the Amazons, legendary woman warriors who were bred from birth for battle. But Belleraphon easily defeated them by dropping rocks on them from above.
When Iobates heard that Belleraphon was on his way back from the land of the Amazons, he sent his entire army out to ambush him. But Belleraphon saw them from above and prayed to his father Poseidon to send a great flood that washed them all back to the castle. As the men fled in panic, the women ran out and hoisted up their skirts, shaming Bellerphon into relenting and the waters receded.
Finally, King Iobates decided Belleraphon must be beloved of the Gods and relented in his attempts to kill him. Instead, he invited him to marry his daughter, Philonoe, the younger sister of Anteia and share half of his kingdom. When big sister heard this, she killed herself.
Philonoe bore Belleraphon Isander, Hippolochus, Deidameia and Laodamia.
The Hubris of Belleraphon
Belleraphon was quite proud of his accomplishments and decided that he would ride Pegasus to Olympus and become as one of the Gods. This was seen as a great offense and zeus sent a gadfly to pester Pegasus who threw Belleraphon off and then quietly returned to the stables of Olympus. Belleraphon fell to the ground and was blinded by thorns. He wandered the earth blind and alone till his death.
