The Alpha star of Andromeda is shared with Pegasus. Andromeda’s eye is called “Alpheratz”, meaning the “horse’s navel” in Arabic. Alpheratz forms the upper left star of the great square and has a 2.1 magnitude. Markab, “saddle”, the lower right star of the square is a 2.5 magnitude white star. Markab is the Alpha of Pegasus. The Beta star is “Scheat,” or shoulder. It makes up the upper right of the great square, a 2.2 magnitude and a deep yellow color. The Gamma star of Pegasus is called “Algenib” and makes up the left-hand corner of the giant square.
There is a small meteor shower from Pegasus during the second week in July called the Pegasides. Remember, to find Pegasus look for the big empty square in the sky; look for nothing. The constellation can be viewed throughout the northern hemisphere and as far throughout Australia and most of South America. It is a favorite constellation to buy a star package to name a star for horse lovers.

Mythology of the Constellation Pegasus
The story of Pegasus starts with the story of Medusa. Medusa was a beautiful woman who was the defiled in the temple of Athena by of Poseidon (Neptune). She was turned into a horrible Gorgon by Athena. As a Gorgon she was a monstrous creature with snakes for hair. Her head would turn all who looked upon it to stone.
Pegasus, the beautiful flying horse, was the son of Neptune and Medusa. He is said to have sprung from the neck of Medusa, whose blood spilled into the ocean after Perseus cut off her head. According to Ovid, Pegasus lived on Mount Helicon, approximately 50 miles north of Athens. There he struck the Earth with his foot he raised the fabled fountain called Hippocrene, “the Horses Fountain”. He became a favorite of the Muses who lived there. The Muses were the 9 daughters of Jupiter (Zeus) and Mnemosyne, the Titan Goddess of Memory.
These 9 sisters ruled the arts and sciences.
Calliope was the goddess of epic poetry.
Clio was the goddess of history.
Erato was the goddess of love poetry.
Euterpe was the goddess of lyric poetry.
Melpomene was the goddess of tragedy.
Polyhymnia was the goddess of sacred poetry.
Terpsichore was the goddess of choral dance.
Thalia was the goddess of comedy.
Urania was the goddess of astronomy.
In one famous myth, Bellerophon, the son of Glaucus was sent to slay the hideous monster Chimera who was destroying Corinth. Bellerophon, after praying in the temple of Athena, was given a golden bridle to harness and break Pegasus, the winged horse. Mounting Pegasus, they rose into the air, found the Chimaera and quickly dispatched him with an arrow. After killing the monster, Bellerophon attempted to fly up to Mount Olympus on Pegasus. Jupiter (Zeus) did not appreciate this arrogance and sent an insect to sting the horse. The startled Pegasus thus threw his rider. Pegasus continued his flight to Olympus where he served Zeus and was later placed among the constellations. Bellerophon, struck blind and lame by the fall, was left to wander the countryside and died lonely and destitute.
