Cronus

• 1. Introduction

  ›

  Cronus, leader of the Titans and ruler of the mythological Golden Age, was the deity Greeks credited with bringing the harvest and feared for devouring his own children. He overthrew his father Uranus by castrating him with a stone sickle, then ruled the cosmos alongside his sister Rhea. That reign was remembered by later Greeks as a time of such moral perfection that people required no laws, and immorality had vanished from the earth entirely. Yet the same deity who presided over this paradise swallowed five of his own children in sequence, terrified that a prophecy would come true. How did the youngest Titan become king of the gods? How did his son Zeus outwit him? And why did a deity the Greeks associated with cruelty become, in Rome, the beloved patron of one of the ancient world's most festive holidays? The answers reach from a cave on Crete to the island later called Corfu, from Athens to the Isle of the Blessed, and from ancient Greece all the way to the naming of the English word for Saturday.

• 2. The Sickle and the Throne

  Gaia, the earth herself, was the one who crafted the weapon. She created a great stone sickle and then gathered Cronus and his brothers, urging them to castrate their father Uranus, who had hidden their youngest siblings, the hundred-handed Hecatoncheires and the one-eyed Cyclopes, in Tartarus so that they would not see the light. Of all the Titans, only Cronus was willing to carry out the act. He lay in ambush, and when Uranus came to meet Gaia, Cronus attacked and castrated him with the sickle.

  From the blood that fell upon the earth, three kinds of beings came into existence: the Gigantes, the Erinyes, and the Meliae. The severed flesh that landed in the sea produced a white foam, and from that foam the goddess Aphrodite emerged. For his act, Uranus cursed his sons, calling them Titenes, a name understood as signifying that they had overstepped their boundaries.

  After the deed, Cronus cast the sickle into the sea near Corfu. Ancient tradition noted that the island itself had a sickle-like shape, and its old name, Drepane, literally meant "sickle," a geographical memory of the founding act of his reign. Cronus and Rhea then took the throne as king and queen of the cosmos, and the age they presided over was remembered as the Golden Age.

• 3. The Children He Swallowed

  ›

  Gaia and Uranus delivered a prophecy to the newly crowned Cronus: he would be overthrown by one of his own children, just as he had overthrown his father. Cronus responded with a strategy as extreme as the prophecy. As each child was born to Rhea, he swallowed them whole. The gods Demeter, Hestia, Hera, Hades, and Poseidon all disappeared into their father before they could draw a single breath of freedom.

  When the sixth child was coming, Rhea sought counsel from Gaia. The plan they devised was quiet and specific. Rhea gave birth to Zeus secretly in Crete, then wrapped a stone in swaddling clothes and presented it to Cronus. One source, De astronomia, adds a detail that sharpens the image: Cronus asked to nurse the infant one last time before swallowing him. Rhea pressed her breast against the rock, and the milk that sprayed across the heavens formed the Milky Way galaxy. Cronus swallowed the stone, believing it to be his son.

  Rhea hid Zeus in a cave on Mount Ida in Crete. According to some versions of the story, a goat named Amalthea raised him there, while armored male dancers called Curetes shouted and clanged their shields to drown out the baby's cries. In another version from the Fabulae, Amalthea was a nymph who placed Zeus in a cradle suspended from a tree, so that he hung between the earth, the sea, and the sky. One Cretan myth adds that Cronus actually came to Crete searching for his son, at which point Zeus transformed himself into a snake and changed his nurse companions, Helice and Cynosura, into bears. Those two bears, the myth says, later became the constellations Ursa Major and Ursa Minor.

• 4. The Titanomachy

  ›

  Once Zeus had grown to full strength, the reckoning came. Gaia's cunning and Zeus's own power together forced Cronus to vomit up what he had swallowed. Cronus first disgorged the stone he had swallowed instead of Zeus, and then each of the five siblings in turn. Zeus later placed that stone at Pytho on Mount Parnassus. In some versions of the story, it was not force alone that emptied Cronus: the goddess Metis gave him an emetic.

  Zeus then freed the Hecatoncheires and the Cyclopes, who had remained imprisoned since before his birth. In gratitude, the Cyclopes gave Zeus his thunderbolts. The war that followed was called the Titanomachy. Zeus, his brothers and sisters, the Hecatoncheires, and the Cyclopes fought against Cronus and the other Titans. When it ended, most of the Titans were confined in Tartarus. A handful, including Oceanus, Helios, Atlas, Prometheus, Epimetheus, and Astraeus, were spared imprisonment.

  The fate of Cronus after that defeat varies across sources. The Iliad, Hesiod's Theogony, and Apollodorus all agree that he was imprisoned in Tartarus with the other Titans. But two papyrus versions of a passage from Hesiod's Works and Days offer a different ending: Zeus eventually released Cronus from Tartarus, and Cronus then ruled over the heroes who dwell in the Isle of the Blessed. The poet Pindar repeated this version in a poem dated to 476 BC, describing the Isle of the Blessed as a place where ocean breezes blow and flowers of gold blaze from splendid trees.

• 5. Cronus Across Cultures

  ›

  Philo of Byblos, writing around 100 AD, recorded a Phoenician tradition in which Cronus was identified with the Semitic deity El. In this account, preserved in Eusebius's Praeparatio Evangelica and ascribed to the ancient Phoenician historian Sanchuniathon, Cronus was originally a Canaanite ruler who founded Byblos. In the 32nd year of his reign, he castrated, killed, and deified his own father, later called Uranus. When ships were invented, this version of Cronus traveled the inhabitable world, bequeathing Attica to his daughter Athena and Egypt to Taautus, the inventor of writing.

  Diodorus Siculus offered yet another account, set in Libya. In his version, Cronus married his sister Rhea after she abandoned an earlier husband, the Libyan king Ammon. Cronus ruled harshly and was eventually defeated not by Zeus directly but by Ammon's son Dionysus, who then appointed Cronus's own son Zeus as king of Egypt.

  In Greco-Roman Egypt, priests at the temple of Tebtunis in the southern Fayyum identified Cronus with the Egyptian god Geb, who held a parallel position as father of Osiris, Isis, Seth, and Nephthys. In temple texts, these priests called themselves priests of "Soknebtunis-Geb" in Egyptian and priests of "Soknebtunis-Cronus" in Greek. Local villagers reflected this equation in naming practices: Egyptian names built from Geb were just as common as Greek names derived from Cronus, particularly the name Kronion.

• 6. Time, Name, and Saturn

  ›

  Ancient writers puzzled over the name Cronus and found in it something deeper than a mere title. The Roman philosopher Cicero, writing in the 1st century BC, argued that the Greek name Cronus was synonymous with chrónos, meaning time, because Cronus maintained the cycles of seasons and the periods of time. Cicero added that the Latin name Saturn derived from the idea of being saturated with years, since Cronus consumed his sons, just as time consumes the ages.

  Plato, writing in the 3rd century BC, offered two interpretations in his Cratylus. One reading connected the name to kóros, meaning "the pure" and "unblemished" quality of mind. The other linked Rhea and Cronus to the imagery of streams: Rhea from rhoē, meaning "river" or "stream," and Cronus from chronos, meaning "time." The Neoplatonist philosopher Proclus, in the 5th century, went further still, arguing in his Commentary on Plato's Cratylus that Cronus was equivalent to the single originating cause of all things.

  A more recent linguistic argument came from Janda in 2010, proposing a genuinely Indo-European etymology: "the cutter," from the root (s)ker-, related to the English word "shear." Janda drew a parallel between the myth of Cronus castrating Uranus and verses from the Rigveda in which Indra's heroic cutting creates the loftiness of the sky. A Hittite parallel exists in the Song of Kumarbi, where the sky deity Anu is castrated by Kumarbi using a similar act of cosmic separation.

  The Roman conflation of Cronus with Saturn gave the deity an outsized role in Western culture. The Saturnalia festival honored him, and a temple to Saturn already stood in the archaic Roman Kingdom. The seventh day of the week, called Dies Saturni in Latin, passed through Old English and became the word Saturday. The planet Saturn, visible to the naked eye and the outermost of the classical planets, still carries his name, and in modern Greek the planet is still called Cronus.

• 7. Harvest God, Festival Figure

  ›

  Before Cronus was the king who swallowed gods, he was likely a deity of the harvest. The month of the harvest in many regions of Greece was named Cronion after him, a linguistic trace of an older agricultural role. In Athens, on the twelfth day of the Attic month of Hekatombaion, a festival called the Kronia was held in his honor to mark the harvest season.

  The satirical writer Lucian of Samosata, writing much later, gave Cronus a voice in a work called Saturnalia, presenting him in dialogue with one of his priests. In that dialogue, Cronus himself rejects the Hesiodic account in which he ate his children and was then overthrown. He claims instead that he peacefully abdicated the throne in favor of Zeus. He also mentions that he still resumes rulership for seven days each year, the duration of his festival, in order to remind humanity of the plenteous and toil-free life they enjoyed under his reign before the Olympians arrived.

  That festive memory attached itself to a star catalogued as HD 240430, which was nicknamed after Cronus in 2017 when astronomers reported that it appeared to have swallowed its own planets. The ancient act that defined his mythology, consuming what he was meant to protect, found a new home in the language of modern astronomy.
