Pegasus was an immortal winged horse of Greek mythology, born at the instant Perseus struck the head from the Gorgon Medusa. He was the son of Poseidon, god of the sea, and of Medusa, and he came into the world alongside a brother, the golden-sworded Chrysaor. For a time the wild stallion belonged to the mortal hero Bellerophon, who rode him against monsters and armies, before Pegasus found a lasting home on Mount Olympus, where Zeus stabled him and set him to drawing the chariot that carried his thunderbolts.
Pegasus’ parentage placed him among the most striking unions in Greek myth. His father was Poseidon and his mother was the Gorgon Medusa. When Perseus beheaded Medusa, Pegasus and his brother Chrysaor, who took his name from the golden sword he was born holding, sprang forth from her severed neck. The brothers went separate ways from there, and it is Pegasus alone whose story continues into the myths that follow.
According to Hesiod, Pegasus’ name comes from the Greek word for springs, pegae, a fitting title for a horse said to have been born near the springs of Ocean. The name proved doubly apt, since Pegasus went on to raise springs of his own wherever his travels later took him.
Yes. As the child of a god, Pegasus was immortal, and his story bears it out: after Bellerophon fell to his death, Pegasus flew on unharmed and eventually reached Olympus, where he was received among the gods rather than left to perish as an ordinary horse would have been. His years of service to Zeus, and the constellation later named for him, mark him as truly divine.
Pegasus’ life carried him through several homes. He was born near the springs of Ocean, at the edge of the world. In his wild youth he roamed freely, favouring the waters of Mount Helicon and the Pierian spring, both sacred to the Muses. Once tamed, he carried Bellerophon across distant lands and skies. Finally, after Bellerophon’s fall, Pegasus made his way to Mount Olympus, where Zeus stabled him among the other divine horses.
Pegasus’ story begins in violence, at the very moment of his mother’s death.
When Perseus beheaded the Gorgon Medusa, Pegasus and his brother Chrysaor did not simply emerge from her body, they sprang forth from her severed neck, fully grown, in one of Greek mythology’s most striking images of birth arising from death.
Hesiod places Pegasus’ birth near the springs of Ocean, the great river the Greeks believed encircled the known world, a fitting birthplace for a horse whose very name would come to be tied to springs and flowing water.
For a long stretch after his birth, Pegasus belonged to no one. He roamed freely and untamed, showing more of his father Poseidon’s command over water than any inclination to serve a god or a mortal. It would take the intervention of Athena herself to bring him under a rider’s control.
Long before he carried a hero into battle, Pegasus was known across Greece for the springs that seemed to follow wherever he went.
Just like his father, Pegasus held power over water. Wherever he struck the ground with his hoof, a spring was said to burst forth, a divine inheritance that marked him as Poseidon’s son as clearly as any resemblance could.
At least two famous springs in Greece, both called Hippocrene, or “Horse Spring,” were widely believed to have been issued forth by Pegasus’ hoof. The better known of the two lay on Mount Helicon, the sacred abode of the Muses. Its waters, when drunk, enthused poets with inspiration and creativeness, linking Pegasus forever with poetic invention.
Pegasus was also drawn to the Pierian spring, another water source associated with him and with the Muses. It was here, according to Pindar, that the wild horse came to drink, and here that his freedom would finally end.
For a brief but eventful period, Pegasus belonged to a mortal, Bellerophon, the celebrated hero and slayer of monsters.
Notoriously wild and free-roaming, Pegasus was finally tamed by Bellerophon, though not by the hero’s strength alone. According to Pindar, one of the most celebrated Ancient Greek poets, Athena gifted him a charmed golden bridle, which Bellerophon used to capture Pegasus when the stallion was drinking at the Pierian spring. Without Athena’s help the wild horse would very likely have stayed beyond any mortal’s reach.
Riding on Pegasus, Bellerophon was capable of overcoming the Amazons, the fire-breathing Chimaera and the warlike Solymi, his winged horse carrying him above dangers that would have overwhelmed a man on foot.
Pegasus was also the means through which Bellerophon exacted his revenge on Jobates’ wife, Stheneboea, who testified falsely against Bellerophon after he had rejected her advances. According to some, Bellerophon afterward offered her a ride on Pegasus, which she gladly accepted; however, as they were flying over the sea, the winged stallion flung her down to its depths.
Bellerophon’s many victories bred a dangerous confidence in him. He came to believe that mortals were not worthy of his presence and that he deserved to live among the gods on Mount Olympus. So he mounted his faithful horse and began the journey upward.
Zeus, angered by Bellerophon’s hubris, sent a gadfly which stung Pegasus badly enough that the winged horse threw his rider down to earth and to his death. Pegasus, freed of his rider, flew on toward the home Bellerophon had tried and failed to reach.
Pegasus succeeded where Bellerophon had failed, arriving at the halls of the gods as a welcome guest rather than an intruder.
After some time, the riderless Pegasus did reach Mount Olympus, the home of Zeus and the other gods.
Rather than turning him away, Zeus stabled Pegasus with his other steeds, granting the winged stallion the place among the gods that his former rider had so fatally sought for himself.
Zeus soon tasked Pegasus with drawing his thunderbolt-carrying chariot, a fitting role for a horse already so closely tied to sky and storm.
After years of service, Zeus awarded Pegasus a constellation, which bears his name to this very day.
Through the Hippocrene spring on Mount Helicon and his close ties to the Muses, Pegasus became a lasting symbol of poetic and artistic inspiration. Poets who invoked his name, or the waters he was said to have raised, called on the same creative force said to flow from beneath his hoof.
As Bellerophon’s mount, Pegasus represented the divine assistance that separated a hero from an ordinary man. His speed and flight allowed Bellerophon to defeat the Chimaera, the Solymi and the Amazons, threats no warrior on foot could have overcome.
Pegasus played a direct part in the justice of his own myths, carrying Stheneboea to her death for her false accusation, and later becoming the unwitting means of Bellerophon’s downfall when Zeus used the gadfly to punish the hero’s hubris.
Pegasus’ final role, drawing Zeus’ thunderbolt chariot on Mount Olympus, marked his passage from a wild creature of nature into a trusted servant of the gods, an honour crowned by his own constellation.
Hesiod is the earliest surviving source to record Pegasus’ birth from Medusa and to explain the origin of his name, tying it to the Greek word for springs and to his birthplace near the springs of Ocean.
Pindar gives the fullest ancient account of Bellerophon’s taming of Pegasus, describing Athena’s gift of the golden bridle and the horse’s capture at the spring.
The Library offers a compact summary of Pegasus’ birth and of his adventures with Bellerophon, drawing together details scattered across earlier poetic sources.
Ovid recounts the making of the Hippocrene spring on Mount Helicon by the strike of the winged horse’s hoof, in the passage where the Muses receive Athena on the mountain, reinforcing the horse’s long ties to poetry.
Perseus is often pictured riding Pegasus in later art and in modern retellings, but that pairing is absent from the ancient sources. Perseus’ connection to Pegasus begins and ends at the moment of the horse’s birth, when Perseus beheads Medusa. It is Bellerophon, not Perseus, who tames and rides the winged horse.
It is often assumed that Pegasus simply drank at the Hippocrene springs, but the ancient tradition credits him with raising them: the waters were said to have burst from the ground at the spot where his hoof struck.
Bellerophon is often remembered as the sole tamer of Pegasus, but the ancient accounts give Athena the decisive part. It was her gift of a golden bridle that made the capture possible at all.
No. It was Bellerophon who fell to his death when the gadfly stung his mount. Pegasus, immortal, flew on and finished his story on Olympus, and many people today meet his name first not through the myth at all, but through the constellation.
Pegasus’ story traces an unusual arc. Born from violence at his mother’s death, he spent his early life as a wild, untamable force of nature, briefly served a mortal hero, and ended his days honoured among the gods. Few figures in Greek mythology move so completely from the edge of the world to a fixed place in the night sky.
What endures about Pegasus is not any single deed but the range of roles he filled: source of poetic inspiration, instrument of both heroism and downfall, and finally a loyal servant of Zeus. That range is likely why his image has outlived so many of the details of his own story.
Hesiod documents Pegasus’ birth and the origin of his name in the early passages of his “Theogony.”
You can read the story of Bellerophon and Pegasus in Pindar’s 13th Olympian Ode, in the thirty or so verses beginning with the 60th. Ovid’s Metamorphoses also preserves the story of the Hippocrene spring.
As is often the case, you can find an informed summary of it in Apollodorus’ “Library.”
