Intro and Visual description
Farther along on the line from the Pointers to Polaris and Cassiopeia is a large, nearly perfect square of four stars. This is the Great Square of Pegasus. Pegasus, the Winged Horse, lies almost directly overhead in autumn. Located east of Andromeda; signals the coming of Fall. Because Pegasus flies so fast, his hind quarters can’t be seen.

Pegasus is included in the ancient star catalogs of Eudoxos of Knidos, Aratos of Soli, and Ptolemy.
