How to find Pegasus

Look for a large square of four stars, the Great Square of Pegasus, high in autumn evenings. One of its corners, Alpheratz, is shared with Andromeda. The horse's head stretches to the star Enif.

The story

Pegasus sprang from Medusa when Perseus killed her. The hero Bellerophon later rode him, and Zeus set the winged horse among the stars.

Worth knowing

The Great Square holds few stars to the eye, so counting the faint ones inside it is an old way to judge how dark the sky is.

Pegasus in six cultures

Around the world

Mesopotamian (Babylonian)

Long before the winged horse, the Babylonians saw a square plot of land here, IKU, "the field". Three of its four stars later became part of the Greek horse.

Greek

Pegasus had magical powers: his hooves dug out a spring, Hippocrene. After his children died, Bellerophon tried to ride Pegasus up to Mount Olympus. Zeus struck him down, with a thunderbolt in some versions and in others a gadfly that made the horse throw him.

Persian

Most mapmakers drew only the front half of a horse, rising out of the sea. In the 10th century the Persian astronomer al-Sufi drew a complete horse facing east, with its head formed from the stars of Lacerta.

Chinese

Chinese astronomers placed these stars in the Black Tortoise of the north. Two stars of Pegasus with one of Aquarius made Wei, a rooftop, with one star as the peak. Alpheratz and Gamma Pegasi made Bi, the Wall: the eastern wall of the imperial palace, or of the emperor's library.

Indian (Hindu)

In Hindu astronomy these stars belong to Purva Bhadrapada, the 25th nakshatra. It was pictured as a bed where the Moon rested.

Warrau and Arawak (Guyana)

For the Warrau and Arawak peoples of Guyana, the Great Square is a barbecue frame. The seven hunters in the story of Siritjo carried it up into the sky.
