Uranus (mythology)

• 1. Introduction

  ›

  Uranus is one of the oldest divine figures in Greek religion, a being so ancient and so vast that he was not a god who ruled the sky but the sky itself. In Hesiod's Theogony, the foundational text that Greeks came to treat as the standard account of their origins, Gaia, the Earth, bore Uranus first of all things after Chaos, creating him as her equal and her cover. He would become both her son and her husband, a union that produced eighteen children. Yet for all that creative power, no cult addressed directly to Uranus survived into classical times. He left no temples, no festivals, no tradition of worship. What remained was a myth so violent and so strange that it shaped the entire Greek understanding of how the world came to be. Why would the Earth conspire against the Sky? Why did a mother hand a sickle of adamant to her youngest son and ask him to do the unthinkable? And how does the name of a planet millions of miles from Earth trace back to a word that simply means rain?

• 2. Name and Its Roots

  ›

  Most linguists trace the name Ouranos back to a Proto-Greek form Worsanós, built from a root also present in the Greek verb ouréo, meaning to urinate, the Sanskrit word varsa for rain, and the Hittite warsa, meaning fog or mist. The fundamental Indo-European root is ṷérs-, meaning to rain or to moisten. On this reading, Ouranos is essentially the rain-maker, or the lord of rain. The same root appears in Sanskrit varṣati, meaning it rains, and in the Avestan phrase for it rained on.

  A rival etymology, considered less likely by scholars, reads the name as meaning the one standing on high, tracing it to a different Proto-Indo-European root that also produced the Sanskrit word varṣman for height or top, and the Lithuanian virṧus for upper or highest seat.

  Georges Dumézil proposed in 1934 that Uranus was identifiable with the Vedic deity Varuna, god of sky and waters. The equation seemed compelling at first glance. Both figures are ancient king-gods; both bind their enemies. Uranus imprisoned the Cyclopes, and Varuna was said to bind the wicked. Robert Graves and others took up the comparison. Yet the etymological equation is now considered untenable by most scholars, even if the mythological parallels remain a subject of comparative study.

• 3. A Family of Monsters

  Hesiod describes Gaia creating Uranus to cover her on every side, as an ever-sure abiding-place for the blessed gods. That role as shelter and foundation gave him enormous procreative weight. Together, Uranus and Gaia produced eighteen children: the twelve Titans, including Oceanus, Coeus, Crius, Hyperion, Iapetus, Theia, Rhea, Themis, Mnemosyne, Phoebe, Tethys, and Cronus; the three Cyclopes named Brontes, Steropes, and Arges; and the three Hecatoncheires, the Hundred-Handed Ones, named Cottus, Briareus, and Gyges.

  Hating these children, Uranus hid them away inside Gaia herself. The source of that hatred is not elaborated in Hesiod, but the consequence was Gaia's rage. She fashioned a sickle of adamant, the mythological substance associated with unbreakable hardness, and appealed to her children to act against their father. Only Cronus, the youngest of the Titans, agreed.

  Apolodorus, writing a different genealogy from Hesiod's, reversed the order of births. In his account the three Hundred-Handers and the three Cyclopes came before the Titans, not after. He also added a thirteenth original Titan, the Titanide Dione, who appears in Homer as the mother of Aphrodite.

• 4. The Castration of the Sky

  ›

  Cronus waited in ambush with the adamantine sickle his mother had made. When Uranus came at night to lie with Gaia, Cronus reached out and castrated his father, casting the severed genitals into the sea. The act transferred cosmic authority: Uranus's castration allowed the Titans to rule and Cronus to assume supreme command of the cosmos.

  Uranus, bleeding and overthrown, named his sons Titans in reproach, a word Hesiod connects to the idea of straining or overreaching, and warned that vengeance for the deed would come afterward. From the blood that fell onto the Earth sprang the Giants, the Erinyes, the avenging Furies, and the Meliae, the ash-tree nymphs. From the genitals themselves, cast into the sea, a white foam spread and grew into the goddess Aphrodite, though Homer held a different view and made Aphrodite the daughter of Zeus and Dione. Some accounts also traced the mythical Phaeacians, the sea-people visited by Odysseus in the Odyssey, to the blood shed at that moment.

  The physical location of the castration attracted competing claims in antiquity. The Alexandrian poet Callimachus, writing around 270 BC, placed Cronus's sickle at Zancle in Sicily, saying it was hidden in a hollow under the ground. The town of Drepanum, the modern Trapani, took its very name from the Greek word for sickle. Another Alexandrian poet, Lycophron, also writing around 270 BC, referred to Cronus's Sickle's leap near Drepanum, apparently describing the moment the weapon was thrown into the sea. The geographer Pausanias recorded a third tradition, placing the throw at a cape near Bolina on the coast of Achaea. The historian Timaeus located the sickle at Corcyra, which the islanders identified as the Phaeacians' home island.

• 5. What the Sky Became

  ›

  After his castration, Uranus receded. The sky no longer came down to cover the Earth at night but held to its place. The scholar Carl Kerényi described the moment as the end of the original begetting. Uranus was scarcely regarded as a full person, aside from the role his genitalia played in the castration myth. He was simply the sky, conceived by ancient Greeks as an overarching dome or roof of bronze, held in place or turned on an axis by the Titan Atlas.

  In the Homeric poems, the word ouranos sometimes appears as an alternative to Olympus as the collective home of the gods. William Sale noted that Olympus is almost always the preferred term for the gods' dwelling place, while ouranos more often refers to the natural sky without implying that the gods live there. Sale concluded that the earliest tradition placed the gods on the actual Mount Olympus, and that the epic tradition by the time of Homer had moved them upward into the sky. By the sixth century BCE, when the cult of a heavenly Aphrodite, Aphrodite Urania, needed to be distinguished from the common Aphrodite of the people, the word ouranos had come to signify purely the celestial sphere.

  Despite this fading from active myth, Uranus was not entirely absent. He is identified on the Gigantomachy frieze of the Pergamon Altar, depicted as bearded and winged, fighting against the Giants with a sword, placed not far from his daughter Themis.

• 6. Competing Genealogies

  ›

  Hesiod's account was treated as standard, but other sources contradicted it at nearly every point. In the lost epic called the Titanomachy, Uranus was apparently the son of Aether, not of Gaia. Other accounts named his father as a figure called Acmon. According to Orphic texts, Uranus and Gaia were both children of Nyx, Night, and the primordial figure Phanes.

  The poet Sappho, writing around 630-570 BCE, made Uranus the father of Eros, the god of love, though she gave two different mothers in different sources: either Gaia or Aphrodite.

  Passages in the Iliad section known as the Deception of Zeus suggest that Homer knew a tradition in which Oceanus and Tethys, not Uranus and Gaia, were the parents of the Titans. Plato, in his Timaeus, offered a genealogy that may have been Orphic in origin and that attempted to resolve this tension. In Plato's account, Uranus and Gaia were the parents of Oceanus and Tethys, and those two in turn were the parents of Cronus, Rhea, and the other Titans, threading both Homer and Hesiod into a single chain.

  In Roman mythology, Uranus's counterpart was Caelus. Cicero traced Caelus to Aether and Dies, Day, making Caelus and Dies the parents of Mercury. Hyginus added that Aether and Dies were also the parents of Terra and Mare, Earth and Sea. One anomaly persists to the present day: when the sixth planet was named in the mid-19th century, it alone among the planets received a Greek name rather than a Roman one, honoring Uranus rather than his Roman equivalent Caelus.

• 7. A Planet Named in Greek

  ›

  The ancient Greeks and Romans knew of only five wandering stars: Mercury, Venus, Mars, Jupiter, and Saturn. When William Herschel discovered a sixth planet in 1781 using a telescope, disagreement over its name lasted for decades. Herschel himself called it Georgium Sidus, the Georgian Star, in honor of his monarch George III. English astronomers preferred that name; the French preferred Herschel. The astronomer Johann Bode proposed Uranus, arguing that the name completed the mythological logic of the solar system. Mars is Ares in Greek, Venus is Aphrodite, Mercury is Hermes; Jupiter is Zeus, the son of Saturn, and Saturn is Cronus, the son of Uranus. The name was accepted in the mid-19th century.

  The anomaly Bode's logic created is one that classicists still note: every other planet in the familiar sequence carries a Roman name, but Uranus is Greek. His Roman equivalent, Caelus, was passed over. The sky god who fathered the Titans and was overthrown by his own son ended up lending his name, and his Greek name specifically, to the frozen giant orbiting far beyond Saturn, completing a mythological family tree that now extends across the outer solar system.
