Pegasus is the winged horse of Greek mythology, most famously born from the blood of the beheaded Gorgon Medusa and tamed by the hero Bellerophon. He appears in ancient Greek and Roman texts and art as a divine steed, a symbol of poetic inspiration, and a constellation in the night sky.
Origins and Birth of Pegasus
The most widely told origin of Pegasus comes from Hesiod’s Theogony (c. 700 BCE). According to Hesiod, when the hero Perseus cut off Medusa’s head, Pegasus sprang forth from her neck, along with the warrior Chrysaor. Because Medusa was a Gorgon who had been impregnated by the sea god Poseidon, Pegasus was often considered Poseidon’s son. This version is the standard one in classical literature.
Some later writers, such as the Roman poet Ovid, offer a slightly different detail, saying Pegasus was born from the blood that dripped from Medusa’s head into the sea. In that telling, his name is sometimes linked to the Greek word pegē (spring or well), because he was born near the springs of Oceanus. However, the core story remains consistent: Pegasus is a divine creature connected to both the Gorgon and the sea god.
Pegasus and Bellerophon
Pegasus is most closely associated with the Corinthian hero Bellerophon. According to the myth, Bellerophon wanted to defeat the Chimera, a fire-breathing monster with a lion’s head, a goat’s body, and a serpent’s tail. He sought Pegasus to help him, but the horse was wild and would not let anyone approach.
The seer Polyeidus told Bellerophon to sleep in the temple of Athena. In some versions, Athena gave him a golden bridle; in others, she showed him where to find Pegasus drinking from the spring of Peirene near Corinth. With the bridle, Bellerophon was able to tame Pegasus, and together they flew into battle and slew the Chimera. This victory made Bellerophon famous, but his later arrogance led to his downfall. He tried to ride Pegasus to Mount Olympus, the home of the gods, and Zeus sent a gadfly (or in some versions, a bolt of lightning) to make Pegasus buck, throwing Bellerophon back to earth. He survived but was crippled and lived the rest of his life in misery.
Pegasus in the Sky: The Constellation
After Bellerophon’s fall, Zeus placed Pegasus among the stars as the constellation Pegasus. This is one of the oldest recognized constellations and is still one of the 88 modern constellations. In the sky, Pegasus is usually depicted as a horse flying upside down or sideways, with its head and forelegs in the northern hemisphere and its body stretching south.
The Great Square of Pegasus, formed by four bright stars, is one of the most recognizable asterisms in the northern sky. The constellation is also home to a famous exoplanet, 51 Pegasi b, discovered in 1995, which was the first planet found orbiting a sun-like star outside our solar system. Though the planet is not part of the ancient myth, its name and location connect modern astronomy to the old story.
Pegasus as a Symbol of Inspiration
In ancient Greek and later Western culture, Pegasus became a symbol of poetic inspiration and intellectual flight. The spring of Hippocrene, which was said to have been created when Pegasus struck the ground with his hoof on Mount Helicon, was sacred to the Muses. Drinking from that spring was said to give poets their inspiration.
This connection to the Muses made Pegasus a favorite emblem for poets and artists. The Roman poet Horace called him the “winged horse” of the soul, and later Renaissance and Romantic writers used him as a metaphor for imagination and creativity. Even today, images of Pegasus appear on logos and emblems of poetry and literary societies, such as the Pegasus Award for science fiction poetry.
Pegasus in Roman and Later Art
The Romans adopted Pegasus from Greek myth and kept his story largely unchanged. They depicted him on coins, mosaics, and sarcophagi, often alongside Bellerophon or as a constellation. In Roman art, Pegasus sometimes appears as a symbol of immortality or of the soul’s journey to the heavens.
In medieval and Renaissance European art, Pegasus was often used in Christian allegory as a symbol of fame, contemplation, or the resurrection. For example, the Italian painter Andrea Mantegna’s Parnassus (1497) shows Pegasus and the Muses on Mount Parnassus, blending classical and Christian themes. Pegasus also appears in heraldry, on shields and coats of arms, as a sign of swiftness and nobility.
Common Misconceptions about Pegasus
A frequent misconception is that Pegasus is the same as the unicorn or that all winged horses in mythology are called Pegasus. In Greek myth, Pegasus is a specific individual, not a species. Other cultures have their own winged horses, such as the Indian Uchchaihshravas or the Norse Sleipnir, but they are separate figures with different stories. Also, Pegasus is sometimes confused with the constellation Equuleus, which is a separate, smaller constellation representing a horse’s head.
Another misconception is that Pegasus was always gentle or friendly. In the myths, he is a wild and untamable creature until Bellerophon uses the divine bridle. Even then, he is not a pet; he is a divine being who serves a hero for a time and then returns to the sky.
Pegasus in Modern Culture and Science
Beyond ancient art, Pegasus has left a mark on modern culture. He appears in movies like Clash of the Titans (1981 and 2010), in fantasy novels such as Rick Riordan’s Percy Jackson series, and in video games like God of War and Assassin’s Creed Odyssey. These modern versions often simplify or alter the myth, but they keep the core image of a winged horse.
In science, Pegasus has given his name to a genus of seamoths (fish with wing-like fins) and to the constellation’s stars. The exoplanet 51 Pegasi b is often called “Bellerophon” in informal contexts, though the name is not official. This shows how the ancient myth continues to inspire naming in new fields.
Frequently Asked Questions
Who were Pegasus’s parents?
In the most common version, Pegasus was the son of Poseidon and Medusa, born when Perseus beheaded her. Some later accounts say he was born from the drops of her blood that fell into the sea, but the parentage remains the same.
Did Pegasus have any siblings?
Yes, in Hesiod’s Theogony, Pegasus had a brother named Chrysaor, who was also born from Medusa’s neck. Chrysaor was not a horse but a warrior, and he is rarely mentioned in other myths.
Why did Bellerophon fall from Pegasus?
Bellerophon became arrogant and tried to fly to Mount Olympus, the home of the gods. Zeus sent a gadfly to sting Pegasus, making him buck and throw Bellerophon to the earth. The hero survived but was crippled, and Pegasus continued to Olympus, where Zeus placed him among the stars.
Is Pegasus a god?
No, Pegasus is not a god but a divine or immortal creature. He is often called a “divine horse” because he was born from a god and a Gorgon, but he does not have his own cult or worship in ancient Greece.
What is the difference between Pegasus and a unicorn?
Pegasus is a winged horse from Greek mythology, while a unicorn is a single-horned horse (or goat-like creature) from various European and Asian legends. They are different creatures with different origins and symbolism.
Where can I see Pegasus in the night sky?
The constellation Pegasus is visible in the northern hemisphere from late summer to autumn. Look for the Great Square of Pegasus, which is formed by four stars: Markab, Scheat, Algenib, and Alpheratz (though Alpheratz is now officially part of Andromeda).
