Pegasus, in astronomy, northern constellation lying SW of Andromeda and SE of Cygnus. It is named for the mythological winged horse Pegasus. The constellation is easily recognized by the Great Square formed by the bright stars Markab (Alpha Pegasi) at the southwest corner, Scheat (Beta Pegasi) at the northwest corner, Algenib (Gamma Pegasi) at the southeast corner, and Alpheratz in Andromeda at the northeast corner. The constellation reaches its highest point in the evening sky in October. In 1995 a planet at least half the size of Jupiter was discovered orbiting the star 51 Pegasus, which is about 40 light-years from the earth; this marked the first time a planet was detected orbiting a sunlike star outside the solar system.
Pegasus, in Greek mythology, winged horse that carries the thunderbolt of Zeus. He sprang full-grown from the neck of the dying Gorgon Medusa. With a slash of his hoof, he created the Hippocrene, a sacred spring of the Muses on Mt. Helicon. Hence, he has often been associated with the arts, especially poetry. Pegasus was captured by Bellerophon, who rode him through many adventures. His name indicates a pre-Greek origin.

In Greek mythology, Pegasus (Greek: Πήγασος, Pégasos, 'strong') was a winged horse that was the son of Poseidon, in his role as horse-god, and the Gorgon Medusa.


Hesiod connects the name Pegasos with the word for "spring, well", pēgē; everywhere the winged horse struck his hoof to the earth, an inspiring spring burst forth: one on the Muses' Mount Helicon, the Hippocrene ("horse spring"), at the behest of Poseidon to prevent the mountain swelling too much and another at Troezen. The actual etymology of the name is most likely from Luwian pihassas "lightning", or pihassasas, a weather god (the god of lightning). In Hesiod, Pegasos is still associated with this original significance by carrying the thunderbolts for Zeus. Pegasus was at a well drinking silently when the hero Bellerophon came and captured him with a golden bridle that was given to him by Athena.


There are two versions of the winged stallion's birth and his brother Chrysaor:

  • One is that they sprang from Medusa's neck as Perseus beheaded her, a "higher" birth, like the birth of Athena from the head of Zeus.
  • Another says that they were born of the Earth as Medusa's blood spilled onto it, in which case Poseidon would not be their sire. A variation on this story holds that they were formed from the mingling of Medusa's blood and the sea foam, thus including Poseidon in their making.

Bellerophon caught and tamed Pegasus, and presented him to the Muses at Mount Parnassus. After he became the horse of the Muses, he was at the service of the poets.


Pegasus aided the hero Bellerophon (or in later versions Perseus) in his fight against both the Chimera and the Amazons. There are varying tales as to how Bellerophon found Pegasus; the most common says that the hero was told by Polyeidos to sleep in the temple of Athena, where the goddess visited him in the night and presented him with a golden bridle. The next morning, still clutching the bridle, he found Pegasus drinking at the Pierian spring. When the steed saw the bridle, he approached Bellerophon and allowed him to ride. Bellerophon slew the Chimaera on Pegasus' back, and then tried to ride the winged horse to the top of Mount Olympus to see the gods. However, Zeus sent down a gadfly to sting Pegasus, causing Bellerophon to fall all the way back to Earth the Plain of Aleion ("Wandering"), where he lived out his life in misery as a blinded cripple as punishment for trying to act as a god. Also, he was kept as Zeus' servant and stayed with him, never seeing Pegasus again.

Afterward, Pegasus found sanctuary on the sacred mountain, where he carried Zeus' thunderbolts and was ridden by Eos, the goddess of dawn.

In his later life, Pegasus took a mate, Euippe (or Ocyrrhoe), and had two children Celeris and Melanippe. This family is the origin of the winged horses. Celeris is associated with the constellation Equuleus.


Pegasus was immortal. Because of his faithful service Zeus honored him with a constellation. On the last day of his life, when Zeus transformed him into a constellation, a single feather fell to the earth near the city of Tarsus.

Modern Day Instances

In psychoanalysis, Freud interpreted the creature as an expression of the primal scene.

World War II

During WWII, the silhouetted image of Bellerophon the warrior, mounted on the winged Pegasus, was adopted by the United Kingdom's newly-raised parachute troops in 1941 as their upper sleeve insignia. The image clearly symbolized a warrior arriving at a battle by air, the same tactics used by paratroopers. The square upper-sleeve insignia comprised Bellerophon/Pegasus in light blue on a maroon background. The insignia was designed by famous English novelist Daphne du Maurier, who was married to the commander of the British parachute forces (and later the expanded British Airborne Forces), General Frederick "Boy" Browning. The maroon background on the insignia was later used again by the Airborne Forces when they adopted the famous maroon beret in Summer 1942. The beret was the origin of the German nickname for British airborne troops, The Red Devils. Today's Parachute Regiment carries on the maroon beret tradition.

During the airborne phase of the Normandy invasion on the night of 5-6 June 1944, British 6th Airborne Division captured all its key objectives in advance of the seaborne assault, including the capture and holding at all costs of a vital bridge over the Caen Canal, near Ouistreham. In memory of their tenacity, the bridge has been known ever since as Pegasus Bridge.

Corporate and Commercial Uses

Pegasus has been the symbol of the Mobil brand of gas and oil, marketed by the Exxon Mobil Corporation, since the 1930s and, more recently, FBR Capital Markets, an investment bank based in Arlington, Virginia. . As such, it has also been a symbol of Dallas, Texas, gracing its skyline atop the Magnolia building.

The Poetry Foundation also uses Pegasus as its logo; the Buell Motorcycle Company uses Pegasus as a visual branding element. The former Pegaso truck maker from Spain derived its name and logo from Pegasus, although the logo portrayed a merely fast, wingless horse silhouette. Reader's Digest also has a Pegasus logo.
