04The myths

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

Cronus waited in ambush when Uranus came to Gaia at night. Gaia had armed him with a sickle of adamant after persuading him to attack his father. Cronus was the only one of Gaia’s sons willing to perform the deed. He struck Uranus and castrated him, then cast the severed genitals into the sea. Uranus was overthrown, and Cronus took his throne as king of the gods.

As Uranus’s head rolled in the dust, it foretold Cronus’s fate. Cronus had seized his father’s throne, but one of his own sons would do the same to him. Other accounts say that Gaia and Uranus gave this warning together. Cronus therefore lived in fear of the children born to him and Rhea. He swallowed his offspring as soon as they were born, seeking to prevent the prophecy.

Blood from Uranus’s wound fell upon Gaia. From it came the Erinyes, spirits who avenged crimes such as parricide, the armed Giants, and the Meliae, nymphs of the ash tree. Foam rose in the sea where Uranus’s severed genitals had fallen, and Aphrodite emerged from it. Some accounts instead connect Aphrodite with the severed genitals themselves.

Cronus later released the Hecatoncheires and the Cyclopes from Tartarus, then imprisoned them there again. Rhea deceived him, and Zeus escaped being swallowed. Cronus was eventually overthrown by Zeus, fulfilling Uranus’s prediction that a son would take his throne from him.

    After Cronus had overthrown Uranus, the god foretold that Cronus would in turn be overthrown by a child of his own.

    Hesiod, Theogony

  3. 3Greek MythologyT1

Gaia urged her children to rise against Uranus. He had confined the Cyclopes in Tartarus, a dark place in the Underworld, and had fathered the Titans with Gaia. The Titans agreed to attack him, but only Cronus, the youngest, accepted the deed. Gaia gave him a sickle, made from flint or another hard substance, and placed him in ambush.

When Uranus came to Gaia, Cronus attacked him and castrated him with the sickle. One account says that Uranus came to lie with Gaia at night. Another says that Cronus surprised him while he slept. Cronus threw the severed parts and the sickle into the sea, with one tradition placing the act by Cape Drepanum. Uranus was thereby separated from Gaia, and his rule over the universe ended.

Blood from the wound fell upon the earth. From it came the Erinyes, spirits who avenge parricide and perjury, named Alecto, Tisiphone, and Megaera. The Giants also arose, fully armed, along with the Meliae, the nymphs of the ash trees. When the severed parts reached the sea, white foam formed around them, and Aphrodite emerged from it as the goddess of sexuality and desire.

Cronus then became king of the gods. In one account, Uranus warned him that a son of his own would overthrow him in the same way. Cronus therefore held his throne under threat, until Zeus later defeated him.

    Quote

    Gaia gave Cronus a sickle, and he ambushed Uranus, severed him, and ended his rule over the gods.

    Hesiod, Theogony

Uranus forced the Cyclopes and the Hecatoncheires back into Gaia after their birth. The six beings caused her great pain. The Cyclopes were Brontes, Steropes, and Arges, each with one eye in the forehead. The Hecatoncheires were Cottus, Briareos, and Gyes, each with one hundred arms and fifty heads. Gaia could no longer bear their imprisonment, so she made a sharp sickle and asked her children to avenge her.

The Titans feared Uranus, but Cronus, the youngest of the twelve Titans, agreed to act. When Uranus came at night to lie with Gaia, Cronus waited in ambush. He struck his father with the sickle and castrated him. Blood from the wound fell upon the Earth. Gaia conceived the Erinyes, spirits of vengeance, the Giants, and the Meliae, ash tree nymphs. The Giants were born fully armed. They were later described as immense beings with gleaming armour and long spears.

Cronus threw the severed genitals into the sea. Foam formed around them, and Aphrodite arose from it. She became the goddess of sexuality and desire. After Uranus had been emasculated, Cronus became king of the gods. He kept that position until his own son Zeus later overthrew him.

    Uranus’s blood brought forth the Erinyes, the Giants, and the ash-tree nymphs, while foam around his severed genitals gave rise to Aphrodite.

  3. 3The Greek MythsT1

Chaos came into being first as a great void. Gaia, the Earth, followed, along with Tartarus, the deepest recess of the Earth, and Eros, the force of desire. Erebus and Night then arose from Chaos. In one account, Night later produced Aether, the bright upper air, and Day with Erebus.

Gaia brought forth Uranus by herself. He was the starry Heaven, equal to her in stature, and covered her completely. She also produced the mountains and Pontus, the deep barren sea. Uranus became her consort, and together they became the parents of the first gods, the Titans.

Their children included Oceanus, Coeus, Hyperion, Crius, Iapetus, Cronus, Tethys, Rhea, Themis, Mnemosyne, Phoebe, Dione, and Theia. Gaia and Uranus also produced the Cyclopes, Arges, Steropes, and Brontes, each with one eye in the forehead. They had three further children, Briareus, Cottus, and Gyges, each with a hundred hands and fifty heads.

Uranus bound the Cyclopes and the hundred-handed beings and cast them into Tartarus, a place of darkness beneath the Earth. Gaia was angered by the loss of her children. Uranus then remained the first ruler of the universe, while his conflict with his offspring began. Another account says that Uranus and Gaia together produced the Titans and other early beings, rather than presenting Gaia’s solitary birth of Uranus as the starting point.

Gaia bore Uranus, the Heavens, and he surrounded her. She also produced the mountains and Pontus, the sea. Uranus then united with Gaia. In one telling, their first children were the Hundred-Handers, Briareus, Cottos, and Gyes. Each had one hundred hands and fifty heads. Gaia next bore the Cyclopes, Arges, Steropes, and Brontes. Each had one eye in the forehead. Uranus bound these children and hurled them into Tartarus, a gloomy place beneath the earth.

Uranus and Gaia then became the parents of the Titans. Their sons were Oceanus, Coeus, Hyperion, Crius, Iapetus, and Cronus, the youngest. Their daughters were Tethys, Rhea, Themis, Mnemosyne, Phoebe, Dione, and Theia. Other tellings named twelve Titans and omitted Dione and Theia. Another telling placed the Titans before the Cyclopes and the Hundred-Handers. The Titans were almost as large as Gaia, and the mountains became their thrones.

Gaia suffered because Uranus had forced the Hundred-Handers and Cyclopes into her. The Hundred-Handers had great strength, and the Cyclopes were wild, one-eyed beings. Gaia could not endure the pain, so she made a sickle and asked her Titan children to avenge her. Only Cronus agreed. He waited until Uranus came to lie with Gaia at night. Then he ambushed Uranus and castrated him with the sickle.

Uranus's blood fell upon the earth. From it came the Erinyes, spirits of vengeance. Some tellings used the names Ouranos and Ge instead of Uranus and Gaia, and Briareos, Cottus, and Gyges instead of Briareus, Cottos, and Gyes.

  3. 3The Greek MythsT1

The newborn monsters were thrust back into Gaia, their mother, by Uranus. They were the Cyclopes, giants with one eye in the forehead, and the Hecatoncheires, or Hundred-Handers, each with fifty heads and one hundred hands. The Cyclopes were Brontes, Steropes, and Arges. The Hundred-Handers were Cottus, Briareos, and Gyes. Uranus hated or feared their strength and hid them from the world. One account places the Cyclopes in Tartarus, the deepest recess of the Underworld.

Gaia suffered from having her children forced back inside her. She had already borne Uranus the Titans, including Oceanus, Coeus, Hyperion, Iapetus, and Cronus, as well as the Titanesses Rhea, Theia, Mnemosyne, Phoebe, Themis, and Tethys. These children were majestic and strong, but the later monsters were hateful to Uranus because of their terrifying forms and power.

Gaia made a sickle and asked her Titan children to avenge her. Only Cronus, the youngest, agreed. He waited until Uranus came to lie with Gaia at night. Then Cronus ambushed him and castrated him with the flint sickle. He threw the severed parts and the sickle into the sea by Cape Drepanum.

Blood from Uranus’s wound fell upon Gaia. From it came the Erinyes, Alecto, Tisiphone, and Megaera, who avenge parricide and perjury. The ash-tree nymphs, called the Meliae, also arose from the blood. Uranus’s imprisonment of the monsters therefore ended with the attack arranged by Gaia and carried out by Cronus.

  3. 3The Greek MythsT1

Uranus became the First One and ruled Sky and Earth, the new boiling seas, and all that lay above, beyond, and between. He sent rain upon Gaia, whose name meant Earth, and the rain filled her hollow places with water. Rivers flowed, while lakes and seas came into being. Under his rule, the world took shape through rain, land, water, and the living things that Gaia bore.

Uranus married Gaia and drew a golden cloud around them. His rain entered the cave of her womb, and she gave birth to the first children. The Hundred-handed Giants came first. Briareus, Gyges, and Cottus had a hundred hands each. The three Cyclopes came next. Brontes, Steropes, and Arges had one eye each, built gigantic walls, and mastered the craft of smithing. Uranus ruled wisely and well, and the lesser gods expected him to remain king forever.

Cronos, his son, praised him loudly and pretended complete devotion. In secret, he planned against his father. Gaia urged Cronos and the other children to act, because Uranus had become their danger. The Cyclopes forged an iron sickle and made a chain strong enough to hold a god. Gaia then brought her children into the plot, and Cronos attacked Uranus.

Uranus was surprised and dismembered. Since the gods were immortal, the act did not end his existence in the manner of a mortal death. After his mutilation, his fate remained unknown. He either died or withdrew from prominence forever. Before he departed, he prophesied that Cronos and the other Titans would be punished for plotting against their father.
