Theseus

Theseus is the hero Athens claimed as its own king: he sails to Crete with the tribute of youths, kills the Minotaur in the Labyrinth and comes back with Ariadne's thread behind him. Plutarch has him die on Skyros, thrown from the cliffs by Lycomedes, and reports that Athens later fetched his bones home on Cimon's trireme after the Pythia told them to. His tomb stood in the middle of the city and was a place of refuge for runaway slaves.

In short

In Apollodorus, Theseus puts himself among the third Athenian tribute to Crete, kills the Minotaur with his fists in the last part of the Labyrinth, and finds his way out by the thread Ariadne gave him.
Plutarch says the thirty-oared galley Theseus sailed in was preserved by the Athenians down to the time of Demetrius Phalereus, with new timbers put in as the old ones were taken out, and became the philosophers' standing example in the question of growth.
Plato records that no one could be publicly executed at Athens while the annual mission to Delos was at sea, which is the law that kept Socrates alive after his trial.
Plutarch has Theseus driven out of Athens by demagogues and factions, and killed on Skyros by Lycomedes, who led him up to the high places on pretence of showing him his lands and threw him down the cliffs.
After the Median wars the Pythia told the Athenians to bring the bones of Theseus home; Cimon took Skyros, dug where an eagle was tearing at a mound, and found a coffin of a man of extraordinary size with a bronze spear and a sword beside it.
Plutarch records the tomb as a sanctuary and place of refuge for runaway slaves and for men of low estate who were afraid of men in power.

The thread in the dark

Theseus reaches the last chamber of the Labyrinth with a thread running behind him and the Minotaur in front. He has volunteered for the third Athenian tribute to Crete, but courage alone cannot bring the captives home. Ariadne has obtained the way out from Daedalus and given Theseus the thread before he enters. In Apollodorus, he kills the Minotaur with his fists, gathers the line and follows it back to the door.

The escape establishes the hero Athens wants to remember: a prince who chooses to share the danger imposed on the city’s young people and ends it. Yet every part of that success depends on someone else. Ariadne supplies the plan, Daedalus supplies the knowledge, and the rescued children give the voyage its public meaning. Theseus sails from Crete with Ariadne and then leaves her on Naxos. The act that saves Athens also begins the abandonment that defines her story.

How a voyage became an Athenian institution

Athens did not let the return end at the harbour. Plutarch says the city preserved Theseus’s thirty-oared galley until the time of Demetrius of Phalerum, replacing rotten timbers as they failed. Philosophers used the repeatedly repaired vessel to argue over whether an object remains the same when every part has changed. The problem later called the Ship of Theseus began as maintenance of a civic relic.

The annual voyage attached to the ship had consequences beyond commemoration. Athens had vowed to send a sacred mission to Delos each year if Theseus and the captives returned. Plato explains that the city allowed no public execution between the crowning of the ship and its arrival home. Its stern was crowned the day before Socrates’s trial, keeping him alive in prison until the vessel came back. A mythic rescue therefore controlled the calendar of Athenian justice centuries after the supposed voyage.

Why the king dies outside his city

Plutarch’s Theseus loses the authority he had won. Factions in Athens overpower him; he sends his children to Euboea, curses the Athenians at Gargettus and sails to Skyros, where his family claims land. King Lycomedes leads him onto high ground on the pretence of showing him the estate. Whether Lycomedes fears Theseus or acts for the Athenian Menestheus, Plutarch leaves unresolved. He throws the exile from the cliffs, and nobody at the time pays much attention to the death.

The ending exposes the limit of Theseus’s power. He can enter the Labyrinth for Athens, but he cannot make Athens continue to accept his rule. The city that made him its founding king allows him to die on another island without honour.

The return Cimon arranged

After the Persian Wars, Athens asks Delphi what to do about the neglected hero. The Pythia orders the Athenians to recover Theseus’s bones, bury them honourably and guard them. Cimon takes Skyros. Plutarch says he notices an eagle tearing at a mound, orders it dug and finds the coffin of an exceptionally large man, with a bronze spear and sword beside it.

Cimon carries the supposed remains home on his trireme. Athens receives them with sacrifices and processions as if Theseus himself were returning. His tomb stands near the centre of the city in Plutarch’s day, but its final use complicates the royal image. It offers sanctuary to runaway slaves and to people of low status afraid of the powerful. Theseus returns not as the king who held Athens, but as the dead protector approached by those escaping mastery.

Athens

Cities

Athens is the city Theseus is king of in the myth and the city that kept his relics. Plutarch says the ship he sailed to Crete in was preserved by the Athenians down to the time of Demetrius Phalereus, and that his bones, brought back from Skyros on Cimon's trireme, were buried in the heart of the city, where the tomb became a place of refuge for runaway slaves.

Sporades

Skyros is where Theseus dies: Plutarch has him driven out of Athens, sail to Skyros where his family held lands, and be led up to the high ground by Lycomedes on the pretence of being shown them, and thrown down the cliffs. Cimon later took the island and dug for the grave where an eagle was tearing at a mound.
