Theseus is the great Athenian hero. He is the founder of the city in the sense in which legendary founders are founders: he is the one who gave Athens its unity, its law, and its sense of itself. He cleared the roads of bandits, slew the Minotaur in the Labyrinth of Crete, fought the Amazons, and went down to Hades in the company of his friend Pirithous. The historical figure, if he existed, has been overlaid by centuries of myth-making; the legendary Theseus is the figure who gave the Athenian democracy its charter myth.
The story of Theseus, more than that of almost any other Greek hero, is the story of a city. Whereas the legends of Heracles are about strength, and the legends of Odysseus about cunning, the legend of Theseus is about the political virtues — about the founding of institutions, the suppression of disorder, the absorption of the surrounding villages into a single city-state, and the tragic but necessary confrontation with death.
Birth and Parentage
Theseus was the son of Aegeus, king of Athens, and Aethra, daughter of King Pittheus of Troezen. The story of his conception was already a tangle. Aegeus had visited Troezen to consult the oracle at Delphi about his childlessness, and Pittheus, hoping to ensure the birth of a great hero, got Aegeus drunk and put Aethra in his bed. On the same night, Poseidon also visited Aethra — and so Theseus had two fathers, an earthly one (Aegeus) and a divine one (Poseidon). The motif of the double father is rare in Greek myth, and it gave Theseus a special status: the mortal king as his political father, the sea god as his divine sponsor.
When Aethra gave birth, Aegeus left the infant in Troezen, hiding his sword and sandals under a great rock. He told Aethra that, when the boy was old enough to lift the rock and take the tokens, he should be sent to Athens. Aegeus then returned home.
The Journey to Athens
Theseus grew to manhood in Troezen, a city of the Peloponnese near the Saronic Gulf. His mother Aethra and his grandfather Pittheus raised him; he was trained in wrestling and the other heroic arts by a series of tutors. When he was sixteen, his mother led him to the rock and told him the truth. He lifted the rock, took the tokens, and announced his intention to travel to Athens by land — not by the safer sea route.
The journey from Troezen to Athens across the Isthmus of Corinth was a heroic road lined with bandits. Each of the bandits on the way had a method of his own for destroying travelers; Theseus was determined to pass through and to do so by defeating each one in his own way. His exploits on the way were:
- Periphetes at Epidaurus, called “the Club-Bearer,” whom he killed with his own club and kept.
- Sinis at the Isthmus, called “the Pine-Bender,” who tied travelers to two bent pines and tore them apart; Theseus tore him apart with his own device.
- Sciron at the cliffs above the sea, who kicked travelers off the rocks into the waters where a giant turtle devoured them; Theseus kicked him off his own rocks.
- Cercyon, a wrestler at Eleusis, whom Theseus defeated in a wrestling match and killed.
- Procrustes of Attica, called “the Stretcher,” who had an iron bed on which he forced travelers to fit — by stretching those too short or lopping off the limbs of those too tall. Theseus fitted Procrustes to his own bed and killed him.
These exploits, told in Plutarch’s Life of Theseus and in various earlier sources, became a standard set-piece of Athenian art. They also serve as a programmatic statement: Theseus would do to Athens what he had done to the bandits — he would break the violence of the old, unorganized world and reforge it into a civilized polity.
The Recognition by Aegeus
When Theseus reached Athens, he found the city in turmoil. Medea had fled there with her young son Medus and had won the heart of Aegeus by promising to cure his childlessness with magic. Aegeus was about to make Medea’s son his heir, displacing Theseus.
Medea, however, recognized Theseus on sight — she had the gift of prophecy, and she knew who he was. She tried to convince Aegeus that the newcomer was a threat. Aegeus, alarmed, sent Theseus against the Marathonian Bull — the very bull that Heracles had brought back from Crete — hoping that the bull would kill him. Theseus, however, killed the bull, sacrificing it to Apollo, and returned to Athens triumphant.
The decisive moment came at a banquet. Aegeus set a cup of wine before his guests. As was customary, Theseus drew his sword to cut the meat of the bull. Aegeus saw the sword, recognized it as the one he had hidden under the rock at Troezen, and dashed the cup from his lips. The wine spilled on the stone floor, and the liberation cup of Athens has been ceremonially poured on the ground in this way ever since, in the festival of the Anthesteria. Theseus was recognized as Aegeus’s son and heir.
The Minotaur
Theseus’s most famous exploit was the slaying of the Minotaur in Crete. The full story is told in the related article on Theseus and the Minotaur. To summarize: King Minos of Crete, after a defeat of Athens, imposed a tribute of seven youths and seven maidens to be sent every nine years (or, in some sources, every year) to be devoured by the Minotaur, the half-man, half-bull creature imprisoned in the Labyrinth designed by Daedalus. Theseus volunteered to go, with the help of Minos’s daughter Ariadne he slew the Minotaur, found his way out using a ball of thread, and fled Crete with Ariadne and the rescued youths. On the way home, however, he stopped at the island of Naxos, and — for reasons that differ between versions — abandoned Ariadne there. He then sailed on to Athens, but in his grief forgot to hoist the white sail signaling success. His father Aegeus, watching from Cape Sounion, saw the black sail and threw himself into the sea in despair. The sea was named the Aegean in his memory.
The Unification of Attica
With Aegeus dead, Theseus became king of Athens. His great political reform, according to Thucydides and Plutarch, was the synoikismos, the unification of Attica: he brought the people of the surrounding towns and villages into a single city-state under one government. He held a great festival of unity, the Synoikia, to mark the occasion. He gave the Athenians the rule of law that distinguished them from the rest of Greece; in the classical period, Theseus was celebrated as the originator of the Athenian democracy (anachronistic, but characteristic of the Greek habit of finding their institutions in the heroic age).
The Amazon Invasion
In the years that followed, Theseus’s abduction of the Amazon queen Antiope (or Hippolyta, depending on the source) led to one of the great set-pieces of Attic legend: the Amazonomachy, the invasion of Attica by a war-band of Amazons. The Amazons besieged Athens, and the battle was fought in the very center of the city, in the area that became the Athenian Agora. The Amazons were defeated but at great cost; the monument on the Athenian Acropolis, the Parthenon, would later be said to commemorate the victory.
Theseus’s son Hippolytus, by Antiope (or by an earlier Athenian woman), would be the subject of one of Euripides’ greatest tragedies. Hippolytus, chaste and devoted to Artemis, was destroyed by the false love of Phaedra, the wife of Theseus, who had fallen in love with her stepson. The story became the model for the European tradition of the “destructive passion” and was later adapted by Racine in Phèdre.
The Friendship of Theseus and Pirithous
Theseus’s friendship with the Lapith king Pirithous is the great example of heroic xenia in Greek legend. The two became friends after Pirithous, who had heard of Theseus’s fame, raided Attica and tried to steal his cattle. The two met in battle, were so struck by each other’s prowess that they stopped fighting, and swore eternal friendship.
The friendship would have fatal consequences. The two men, in a drunken boast, swore to marry daughters of Zeus. Theseus abducted the young Helen of Troy (who was not yet a teenager) and left her with his mother Aethra at Troezen until she was old enough to marry. He and Pirithous then descended into Hades to abduct Persephone, the queen of the underworld, for Pirithous to marry. This was sacrilege. The two were bound to chairs of forgetfulness by Hades, where they sat for years — until Heracles came to the underworld on his twelfth labor and freed Theseus (Pirithous was left behind for his greater sin).
The freeing of Theseus by Heracles is one of the great interconnections of the Greek heroic cycle.
The Exile and Death of Theseus
Theseus’s later years were unhappy. The abduction of Helen had led to the Dioscuri (Castor and Polydeuces, her brothers) sacking Athens to take her back. The Amazonomachy had weakened the city. His son Acamas (or Menestheus) was said to have begun plotting against him. When the Dioscuri returned, Theseus lost power and was forced into exile.
He went to the island of Skyros, whose king Lycomedes received him hospitably at first. But the king feared Theseus’s great reputation and reputation for daring. He led Theseus to a high cliff overlooking the sea, on the pretext of showing him his lands, and pushed him over. Theseus fell to his death.
In the classical period, especially after the Persian Wars, the Athenians developed a cult of Theseus as a national hero. Cimon, the great Athenian general, was said to have retrieved Theseus’s bones from Skyros and reburied them in the heart of Athens, in a sanctuary called the Theseion. The bones were the official symbol of Athenian political legitimacy: a tomb at the center of the city, a hero to watch over the democracy.
Symbolism and Cultural Legacy
Theseus is the Greek hero of the polis — of the political community. Where Heracles and Perseus perform deeds that belong to the cosmos, Theseus founds a city. The Athenian democracy saw itself as the inheritor of Theseus’s synoikismos; the Persian Wars were fought, in part, in the name of the same political ideal. The Theseion, at the center of Athens, was the place where the citizens of Athens were reminded, every day, that they were the heirs of a hero who had unified a country.
In modern times, Theseus has been a touchstone for political thought. The “Ship of Theseus” — the puzzle of whether a ship whose planks are replaced one by one is still the same ship — has been a favorite philosophical puzzle since Plutarch. In the arts, the Minotaur has proved a particularly durable image: the half-animal man, imprisoned in a maze, the symbol of that which cannot be assimilated. The Minotaur of Picasso and the Minotaur of Dürer are among the most striking modern uses of the myth.
