Pegasus, the divine pure white winged stallion of Greek mythology, was born from the blood of his mother, the Gorgon Medusa, when she was decapitated by Perseus. He was captured by the Greek hero Bellerophon and the two shared many adventures. However, Bellerophon grew proud and decided to ride to Mount Olympus, the home of the gods. The king of the gods, Zeus, was understandably annoyed and sent a fly to sting Pegasus, causing Bellerophon to fall back to Earth where he lived out his days as a homeless cripple. Eventually Zeus placed Pegasus in the sky as a constellation.

The asterism known as the 'Great Square of Pegasus' is comprised of the stars α Peg, β Peg, α And, and γ Peg.
