Pegasus was a winged horse of Greek mythology. He was the son of Medusa – the Gorgon, and Poseidon – the god of the sea and of horses. His name comes from the Greek pagai, meaning springs or waters.
When Perseus cut the head off the pregnant Medusa, Pegasus sprang from her body – as did the warrior Chrysaor.
Pegasus flew to Mount Helicon in Boeotia, home of the Muses. He struck the ground with his hoof, starting a spring in the rocks, named Hippocrene – horse fountain.
The Greek hero Bellerophon later found Pegasus and tamed him with a golden bridle given to him by the goddess Athene – who had turned Pegasus’s mother, Medusa, from a pretty lady into a snake-haired monster.
After some adventures, Bellerophon tried to fly Pegasus to join the gods on Olympus. He fell back to Earth but Pegasus made it to Olympus and then carried thunder and lightning for Zeus.
