Pegasus

The Winged Horse · Bearer of Zeus’s Thunderbolts · Striker of Hippocrene

01Identity

Pegasus is the winged horse that sprang fully grown from Medusa’s severed neck when Perseus cut off her head. He struck Mount Helicon with his hoof, causing Hippocrene, the horse’s spring, to burst from the rock and linking him with the Muses and poetic inspiration. In another tradition Zeus’s gadfly caused Bellerophon to fall from Pegasus, after which the horse continued to Olympus, served among Zeus’s steeds, carried his thunder and lightning, and became a constellation.

04The myths

4 myths, each traced to its primary text and corpus sources.

Perseus stood over the sleeping Medusa and looked at her reflection in his bronze shield. Athene guided his hand, so he did not meet the Gorgon’s gaze. He struck with his sickle and cut off her head. He lifted it by the serpent locks and placed it in his wallet.

As Medusa’s head was severed, Pegasus and Chrysaor sprang fully grown from her body. Pegasus was a winged horse. Chrysaor appeared as a warrior holding a golden sword or falchion. They had been conceived earlier by Medusa and Poseidon. One account says that Pegasus emerged where Medusa’s blood fell upon the ground. Perseus was surprised by their appearance and left them without further conflict.

Stheno and Euryale awoke and pursued Perseus, but he escaped because his helmet made him invisible. Pegasus later came into the care of the gods. Hesiod says that he lived with Zeus and carried the god’s thunder and lightning. Another account says that Athena caught and tamed him, then presented him to the Muses. A kick from Pegasus’s hoof opened the fountain Hippocrene on Mount Helicon, the Muses’ mountain.

Pegasus became the horse of Bellerophon. Athena gave the hero a golden bridle and instructed him to sacrifice a white bull to Poseidon, Pegasus’s father. Once Bellerophon had tamed the horse, he rode him against the Amazons, the Solymi of Lycia, and the fire-breathing Chimaera. Pegasus therefore passed from Medusa’s death to the service of gods, the Muses, and a mortal hero.

    When Perseus cuts off Medusa’s head, Pegasus and Chrysaor spring from her neck, and Pegasus afterwards bears Zeus’s thunder and lightning.

Pegasus struck Mount Helicon with his hoof, and water burst from the rock. The spring was called Hippocrene, a name meaning “horse’s spring”. Mount Helicon was sacred to the Muses. Hippocrene therefore became associated with the Muses and with poetic inspiration.

Pegasus was a winged horse. In one account, he was the child of the Gorgon Medusa and Poseidon. When Perseus cut off Medusa’s head, Pegasus sprang fully grown from her severed neck with his brother, the giant Chrysaor. Another account says that Pegasus arose when Medusa’s blood sank into the earth. Athena caught and tamed him, then presented him to the Muses.

Hesiod gives a different account of the waters connected with the Muses. He says that they washed their skin in Permessus, the Hippocrene, or the holy Olmeius. He does not say that Pegasus created the spring. The tradition that Pegasus opened Hippocrene with his hoof became established later. The spring was then thought to give poetic inspiration to those who drank from it. Visitors were told that its water was the pure water of the nine Muses.

    The Theogony names Permessus, Hippocrene, and holy Olmeius as waters where the Muses washed, but does not say that Pegasus made the spring.

    Hesiod, Theogony

Zeus freed the Cyclopes from their bondage beneath the Earth. In one telling, Cronos had imprisoned them after taking power. In another, Ouranos had first cast them into Tartarus, and Cronos had confined them there again. Zeus acted with the help of Metis, who gave Cronos a drug. Cronos swallowed it and disgorged the stone and the children he had swallowed. The Cyclopes then returned to the world.

The Cyclopes gave Zeus thunder, lightning, and the thunderbolt as thanks for their freedom. They gave Pluto the cap of invisibility and Poseidon the trident. In the telling attributed to Hesiod, the thunderbolt and lightning were objects that the Cyclopes had made. Zeus took these weapons into his struggle against Cronos and the Titans.

Zeus and his allies fought Cronos and the Titans for ten years. Zeus then freed the Hundred-Handers from their bondage beneath the Earth. They joined his side and helped him defeat the Titans. After the victory, many of the Titans were confined in Tartarus, while Oceanus, Helios, Atlas, Prometheus, Epimetheus, and Menoetius escaped that fate.

Gaia bore Typhoeus to avenge the imprisoned Titans. Typhoeus had many snake-headed necks and threatened to rule mortals and immortals. Zeus seized thunder, lightning, and the smoking thunderbolt, then leaped from Olympus and struck the monster. The blows crippled Typhoeus, burned his heads, and set the Earth burning in many places. Zeus defeated him and hurled him down to the Earth. Pegasus did not enter Zeus’s service in this telling, and no event placed him beside Zeus or carrying the god’s weapons.

    The Theogony says that the Cyclopes gave Zeus thunder, lightning, and the thunderbolt after he freed them, but it does not connect Pegasus with these weapons.

    Hesiod, Theogony

Bellerophon rose higher and higher on Pegasus, bursting through the clouds and passing the tallest mountains. After defeating the Chimaera, he had become king of Lycia. The Lycian king had given him the crown and his daughter Philonoé in marriage. Bellerophon and Pegasus had also defeated fierce tribes, and their victories were celebrated throughout Greece. Bellerophon now believed that the gods would welcome him on Mount Olympus. Pegasus knew that the attempt was wrong, but Bellerophon insisted that they continue.

Zeus saw the mortal flying towards heaven on the golden-winged stallion. Angered by Bellerophon’s presumption, he sent a gadfly against Pegasus. One account describes it as large as a crow, with a sting like a dagger. It stung the horse under the tail. Pegasus bucked violently and threw Bellerophon from the saddle.

The sources differ about the injury caused by the fall. One says that Bellerophon lost his eyesight. Another says that he shattered both legs. A further account says that he fell into a thorn-bush. In all these versions, he was left lame, blind, or both, and separated from human society. One tale says that his faithful horse, Sea Mist, found him before he reached a forest and carried him away. Another says that he wandered alone, avoiding the paths of men, until death overtook him.

Pegasus completed the journey to Olympus. Zeus kept him among the heavenly steeds and used him to carry his thunderbolts. Pegasus brought Zeus thunder and lightning when required. Zeus later placed the horse among the constellations, where he became a star figure in the sky.
