Zeus

Also Known As: Greek Ζεύς, genitive Διός; Doric Δεύς; Mycenaean Linear B di-we, di-wo; vocative Ζεῦ πάτερ, “Zeus father”; from Proto-Indo-European *Dyēus, the daylight sky; equated with Roman Jupiter and Etruscan Tinia
Region/Culture: Southern Europe
Mythos: Greek Mythology
Primary Type/Nature: Gods and Deities
Mythical Attributes: He commands the thunderbolt, the storm and the weather, and holds the authority that binds oaths, hospitality and the settled order of the cosmos.
Role in Mythos: Zeus overthrows his father Cronus, distributes the world among his brothers, and rules from Olympus as the final arbiter of gods and mortals.
Relation to Humans: He was the god Greeks appealed to as guardian of guests, suppliants, oaths and household boundaries, and the one who sent rain, lightning and omens. He also took human lovers constantly and fathered a great part of the heroic genealogy, which made him both the protector of mortal law and its most conspicuous violator.

The great altar at Olympia was never built. It accumulated. Century after century of burned thighbones and fat, the ash raked up and wetted with water carried from the Alpheios and packed down into a grey mound that rose higher than a man and kept rising, the smell of scorched grease worked permanently into it. Everything the Greeks felt about Zeus is in that heap. He was less a god you visited than a god you kept feeding.

He is also older than Greek. The vocative that Homer’s characters use, Zeu pater, is the same phrase preserved in Latin Iuppiter and in the Vedic Dyaus Pitar, all of them descended from a Proto-Indo-European name for the bright daylight sky. Clay tablets from Knossos and Pylos already record offerings to di-we centuries before the Iliad. Whatever else the Greeks did with him, they did not invent him. They inherited a sky and gave it a face, a temper and a family.

The family nearly ended him at birth. Cronus, warned that one of his own children would unseat him as he had unseated his father Uranus, swallowed each newborn as it came. Rhea, carrying the sixth, went to Crete and gave birth in secret, then handed her husband a stone bundled in swaddling cloth. He took it without looking. The infant was hidden in a cave on Ida or on Dikte, depending on which local claim you follow, nursed by the goat Amaltheia, and guarded by the Kouretes, armed young men who danced around him beating spear on shield so that the noise of bronze would cover the sound of a baby crying. It is a strange image for the birth of the lord of order: a god kept alive by percussion.

Grown, he forced Cronus to bring the others back up, stone first, and the war that followed lasted ten years. What broke the deadlock was not strength but recruitment. Zeus went down into the earth and freed the Cyclopes, who in gratitude gave him the thunderbolt, and the Hecatonchires, hundred-handed and monstrous, who could throw three hundred boulders in a single volley. The Titans went down into Tartarus behind bronze gates. Afterwards the three brothers drew lots for the inheritance: Poseidon took the sea, Hades the mist and the dark, and Zeus took the wide sky, with the earth and Olympus held in common. He drew the best portion and everyone knew it.

Gaia was not finished. Her last child was Typhon, a thing with a hundred serpent heads that spoke in every voice at once, bellowing, hissing, lowing like a bull. The fight scorched the earth until Zeus pinned him and buried him, and the volcanic ground of Sicily was afterwards explained as a monster still breathing under Etna.

The cleverest thing he ever did involved no lightning at all. Warned that his first wife Metis would bear a son greater than his father, exactly the trap that had caught Cronus and Uranus before him, Zeus swallowed Metis herself while she was pregnant. Athena was later born fully armed from his head. He had eaten the prophecy rather than the child, and with that the succession of sky gods stopped. The cosmos had reached its last king.

What followed was an office rather than an adventure. Zeus Horkios watched over oaths and destroyed those who broke them; his statue at Olympia stood where athletes swore to compete fairly. Zeus Hikesios protected suppliants. Zeus Herkeios stood inside the courtyard wall and Zeus Ktesios among the storage jars, and Zeus Meilichios, the one who can be appeased, was worshipped in the form of a great snake. Above all he was Xenios, the god of guests. A stranger arriving at a strange door at dusk, dirty and unnamed, was under the protection of the largest god there was, and a household that turned him away was not being rude. It was committing a crime against heaven.

He spoke through landscape as much as through law. At Dodona in Epirus, where offerings had been left since the second millennium, the oracle was an oak, and priests called the Selloi slept on bare ground and left their feet unwashed so as to stay in contact with the earth, then listened to the rustle of the leaves and told enquirers what the tree had said. Hundreds of the questions survive on folded strips of lead, most of them small and human: whether to marry, whether the child is mine, whether to keep sheep. On Mount Lykaion in Arcadia the same god had a darker face. Lycaon served him a dish of human flesh to test whether the guest was really divine, and was turned into a wolf for it, and rumours of what the Arcadians did on that summit never quite went away.

His pursuit of mortal women runs through the whole heroic corpus and it almost always involves a change of shape. He came to Europa as a white bull so gentle she climbed on his back, to Danae as a shower of gold through a bronze roof, to Leda as a swan, to Callisto in the borrowed form of Artemis, and he carried off the boy Ganymede as an eagle. Semele, persuaded by a disguised Hera to demand he appear in his true form, was burned to nothing by the sight. Hera’s jealousy is the engine of half of Greek myth, and it is worth saying plainly that she is usually reacting to something real.

Artists settled early on how he looked. Bearded, long-haired, thickly muscled but not young, either striding with the bolt cocked back over his shoulder or seated with a sceptre and an eagle. The most famous version, Pheidias’ chryselephantine statue at Olympia, sat some twelve metres high in ivory and gold and was counted among the wonders of the world; visitors said that if it stood up it would take the roof off.

His powers follow from the office. The weather is his to give or withhold, thunder is his signature, and no oath, guest-right or judgment holds any force except through him. He knows what is going to happen and he can move it about at the edges.

What he cannot do is unmake it. In the Iliad he twice lifts a pair of golden scales and weighs two dooms, and once the pan sinks he does nothing but watch. When his own son Sarpedon came to the day of his death under Patroclus, Zeus considered snatching him out of the fighting, and Hera told him coldly that every other god would then want the same for their children. He rained blood on the ground and let the boy die. Even his authority among the gods has been tested; Homer mentions a conspiracy in which Hera, Poseidon and Athena bound him, and he was freed only because Thetis fetched the hundred-handed Briareus to sit beside his throne. Prometheus held a secret that could have ended him and traded it under torture. And on Crete they showed visitors a tomb and said the god was buried in it, which is why an old slander about Cretan honesty stayed in circulation for a thousand years.

Frequently Asked Questions

Who is Zeus in Greek mythology?

Zeus is the Greek god of the sky, storm and thunder, and the king of the gods on Mount Olympus. He is the youngest son of the Titans Cronus and Rhea, and he took power by overthrowing his father. His name descends from a Proto-Indo-European word for the daylight sky and is related to the Roman Jupiter.

How did Zeus become king of the gods?

Zeus escaped being swallowed at birth because his mother Rhea gave Cronus a stone wrapped in cloth instead, and he was raised in secret on Crete. Grown, he forced Cronus to disgorge his siblings and fought the Titans for ten years. He won after freeing the Cyclopes, who gave him the thunderbolt, and the hundred-handed Hecatonchires, and the defeated Titans were imprisoned in Tartarus.

What is Zeus the god of besides thunder?

Beyond weather and lightning, Zeus is the guarantor of oaths, hospitality and suppliants. As Zeus Xenios he protected travellers and guests, as Zeus Horkios he punished perjury, and as Zeus Herkeios and Zeus Ktesios he guarded the household courtyard and its stores. These roles made him the enforcer of ordinary social law, not simply a storm god.

Why did Zeus turn into animals?

Zeus changed shape to approach mortal lovers, appearing as a white bull to Europa, a swan to Leda, an eagle to carry off Ganymede, and a shower of gold to reach Danae in her sealed chamber. He also took the form of the goddess Artemis to deceive her follower Callisto. These transformations produced much of the heroic genealogy of Greek myth.

Was Zeus more powerful than fate?

No. In the Iliad Zeus holds up golden scales to weigh two dooms and abides by the result, and when his son Sarpedon reaches his appointed death he considers intervening, is talked out of it by Hera, and lets him die. He can delay and rearrange events, but the sources consistently show him yielding to what is destined.
