"There are two versions of the winged stallion's birth and his brother Chrysaor:

* One is that they sprang from Medusa's neck as Perseus beheaded her [1], a "higher" birth, like the birth of Athena from the head of Zeus.
* Another says that they were born of the Earth as Medusa's blood spilled onto it, in which case Poseidon would not be their sire. A variation on this story holds that they were formed from the mingling of Medusa's blood and the sea foam, thus including Poseidon in their making.

Bellerophon caught and tamed Pegasus, and presented him to the Muses at Mount Parnassus. After he became the horse of the Muses, he was at the service of the poets."
