Boreas

The storm the Athenians called family

A storm rises off Euboea while the Athenian fleet waits near Chalcis. Across the water, hundreds of Persian ships lie exposed along the coast of Magnesia. The Athenians sacrifice and call on Boreas and Oreithyia to destroy the invading fleet.

Their argument is kinship. An oracle has told them to summon their son-in-law, and Boreas has an Athenian wife: Oreithyia, daughter of the ancient king Erechtheus. Herodotus does not confirm that a god causes the storm. He records the Athenian claim and the outcome. Ships break against the Sepian headland and are driven ashore while the north wind blows for three days.

When the Athenians return home, they establish a sacred precinct to Boreas beside the Ilissos. A wind feared for its violence has been brought inside the city’s family and given a place on its ground.

Dawn and dusk produce the winds

Hesiod makes Boreas a son of Eos, Dawn, and Astraeus, the god associated with dusk. His brothers include Zephyrus, the west wind, and Notus, the south wind. The same parents produce the Morning Star and the other stars, placing winds and lights within one line of the sky.

The genealogy distinguishes these winds from another kind. After Zeus defeats Typhoeus, Hesiod says the harmful gusts that scatter ships and destroy crops come from the monster, except for Notus, Boreas and clear Zephyrus. Boreas can still be destructive, as the Persian wrecks show, but he belongs to the ordered divine world rather than the aimless storms outside it.

As north wind, he is both direction and force. The myths give that force a body capable of desire, fatherhood and allegiance without making it gentle.

Oreithyia beside the Ilissos

Apollodorus places Oreithyia by the Ilissos when Boreas carries her off. She is playing beside the river; he takes her and fathers four children with her. Their daughters are Cleopatra and Chione. Their sons Zetes and Calais are winged, sail with Jason and pursue the Harpies from the blind prophet Phineus.

Plato’s Phaedrus walks through the same Athenian landscape. Phaedrus asks Socrates whether the abduction happened beside the clear stream where they stand. Socrates places it farther downstream near the crossing to Agra and says an altar of Boreas is somewhere nearby.

He then considers a rational explanation: perhaps a gust pushed Oreithyia from the rocks, and her death became a divine abduction. Socrates declines to spend his life reducing every strange creature and story in that way. The exchange preserves both the topography and ancient doubt. Athens could point towards the place without requiring one account of what occurred there.

From abductor to ally

The Persian War changes the public use of the marriage. Oreithyia’s abduction is an act of force against a daughter of Athens. In Herodotus, the resulting relationship allows Athens to address Boreas as an ally. The city turns a violent union into a claim upon the wind.

That claim is carefully limited. Herodotus says he cannot tell whether Boreas truly attacks the Persians. The Athenians believe he has helped them once before at Athos and acts again at Artemisium. Their sanctuary beside the Ilissos records gratitude for the aid they think they received.

The landscape holds the story’s two sides close together. By the river, Boreas takes Oreithyia; beside the same river, the city later honours him. A myth of seizure becomes civic theology, and weather becomes a relative who can be petitioned when ships approach.

Boreas never ceases to be dangerous. The point of the Athenian story is not that the north wind has softened. It is that his violence can be directed away from the city and towards the fleet threatening it.
