According to Hellenic mythology, Pegasus was a winged horse, born from the blood of Medusa, when he was beheaded by Perseus. Athenaeus donated it to the hero Bellerophon so that he could destroy the Chimera, which besieged the region of Lydia. From a kick given by the animal on earth, the Hippocrene spring arose, which conferred the gift of song to anyone who drank from its waters. From Pegasus' relationship with this fountain and with the Muses comes the modern use of the winged horse as a symbol of poetry. However, once the Chimera was defeated and dead, Bellerophon became vain to the point of pretending-to show his power-to reach the heavens on the back of Pegasus. Zeus irritated, sent against him a horsefly that stung the winged horse making the hero fall into the void. After this incident, Pegasus was left in the service of the highest deity of Olympus.
