Mythology of the Pegasus Constellation
Pegasus was known to the Greek mythology – he was a white-winged horse that was involved in the Gorgona Medusa and Perseus battle.
Medusa was a beautiful woman and had many admirers. The Goddess Athena caught her being defiled by the sea god Poseidon in her temple and turned her into a cold-blooded creature with the ability to turn everyone who looks at her into a stone. Medusa’s hair transformed into snakes and she became ugly. Hero Perseus was sent to kill her both with his fellow companion Pegasus.
Another story is a story of a young Pegasus and his outstanding mythical powers. When Pegasus was born, he flew away to the Mount Helicon in Boeotia. That was the home of the Muses, and after he became friends with them, they named him Hippocrene – the horse’s fountain. It was believed that everyone who drank from it was gifted with writing poetry talent.
The most famous myth with Pegasus is the one of Bellerophon, a hero sent to kill the Chimaera monster that breathed fire and was ruining King’s land. Bellerophon captured Pegasus and tamed him using a golden bridle. Pegasus helped him defeat the Chimaera monster, and the two rode together on Olympus to join the gods. The hero, unfortunately, fell off the horse and was brought back to Earth, but Pegasus managed to arrive at the location. He was a companion of Zeus, and Zeus wanted to honor him for his outstanding service and decided to place him on the night sky as a constellation.
