Greek Hero

Theseus

Theseus was an Athenian hero who defeated and killed the Minotaur. As king of Athens, he expanded the city’s power and perfected its government. In later Greek history, Theseus came to symbolize the greatness of Athens.

  • Did Theseus kill the Minotaur?

    Yes. Theseus killed the Minotaur when he was sent to Crete as a tribute.

  • Did Theseus kill Medusa?

    No. Medusa was killed by the Argive hero Perseus.

  • Did Theseus marry Ariadne?

    No. Ariadne helped Theseus kill the Minotaur, and Theseus took her with him when he left Crete. However, he left her on the island of Naxos on his way back to Athens.

Theseus was by far the most famous and important of the mythical kings of Athens. But Theseus was raised by his mother, Aethra, in the Peloponnesian city of Troezen. He did not even see his father, Aegeus, or the city he would make famous until he was already a man. In fact, the identity of Theseus’ father was kept secret from him until he had grown up and could prove himself. And prove himself he did. Theseus, like the hero Heracles, travelled widely and slew fearsome monsters before becoming king. 

Shortly after finally meeting his father, Theseus voyaged to the island of Crete. While there, he fought and killed the Minotaur, a half-bull, half-man hybrid imprisoned in a maze called the Labyrinth. Later, as king of Athens, Theseus expanded the boundaries of his kingdom and dramatically improved the government. 

Though a great hero, Theseus’ life was not without its disappointments and grief. Theseus could be thoughtless or hasty: his failure to follow his father Aegeus’ instructions when he came back from Crete caused Aegeus’ death, and his quick temper cost him the life of his son Hippolytus. 

Theseus also had a weakness for women, to whom he was not always loyal. He had many lovers and wives throughout his storied career, including Ariadne, Antiope (sometimes called Hippolyta), Phaedra, and Helen. Theseus finally died in exile, under suspicious circumstances.

Etymology

The name Theseus was likely derived from the Greek word θεσμός (thesmos), which means “institution.” Theseus’ name thus reflects his mythical role as a founder or reformer of the Athenian government.

Attributes

In his iconography, Theseus is usually depicted as a handsome, strong, and beardless young hero. Theseus’ battle with the half-bull Minotaur was an especially popular theme in Greek art.

Family

Theseus’ father was either Poseidon, the god of the sea, or Aegeus, the king of Athens. His mother was Aethra, the daughter of King Pittheus of Troezen. Through Aegeus, Theseus’ lineage can be traced back to Erechtheus (sometimes called Erichthonius), the son of Hephaestus and the first king of Athens. Theseus’ maternal grandfather, Pittheus, was a son of Pelops and thus the grandson of the infamous Tantalus, whose hubris literally earned him a special place in Hell.

Theseus married several times and took many lovers. He had several sons, the most famous of whom was the ill-fated Hippolytus.

Mythology

Birth

Theseus was the son of Aethra, the daughter of King Pittheus of Troezen, and either Aegeus or Poseidon. Aegeus, who was the king of Athens, had no children and therefore no heir to his throne. Hoping to remedy this, Aegeus went to Delphi, where he received a strange prophecy:

The bulging mouth of the wineskin, O best of men, loose not until thou hast reached the height of Athens.1

On his way back to Athens, Aegeus stopped at Troezen, where he was entertained by King Pittheus. Aegeus revealed the prophecy to Pittheus, who understood its meaning and plied Aegeus with wine. Aegeus then slept with Pittheus’ daughter Aethra. 

Before leaving Troezen, Aegeus hid a sword and sandals under a large stone. He told Aethra that if she had a son, she should wait until he had grown up and bring him to the stone. If he managed to lift it and retrieve the tokens, he should be sent to Athens.

According to other versions, Aethra had also been seduced by the god Poseidon, and it was he who was Theseus’ father.2 In any case, Theseus grew up to be a strong and intelligent young man. When he had come of age, his mother took him to the stone where Aegeus had long ago deposited his sword and sandals. Theseus successfully retrieved these tokens and left for Athens to find his father.

Journey to Athens

Instead of travelling to Athens by sea, Theseus decided to make a name for himself by taking the more dangerous overland route through the Greek Isthmus. At the time, it was plagued by bandits and monsters. On his way to Athens, Theseus cleared the Isthmus in what are sometimes called the “Six Labors of Theseus”:

  1. At Epidaurus, Theseus met Periphetes, famous for slaughtering travellers with a giant club. Theseus killed Periphetes and claimed the club for himself.

  2. Theseus then met Sinis, who would bend two pine trees to the ground, tie a traveller between the bent trees, and then let the trees go, thus tearing apart the traveller’s limbs. Theseus killed Sinis using this same method. He then seduced Sinis’ daughter Perigone, who later gave birth to a son named Melanippus.

  3. Theseus next killed the monstrous Crommyonian Sow (sometimes called Phaea),3 an enormous pig that terrorized travellers.

  4. Near Megara, Theseus met the robber Sciron, who would throw his victims off a cliff. Theseus, as usual, used his opponent’s method against him and threw Sciron off a cliff.

  5. At Eleusis, Theseus fought Cerycon, who challenged travellers to a wrestling match and killed whomever he defeated. Following this model, Theseus wrestled Cerycon, beat him, and killed him.

  6. Finally, Theseus defeated Procrustes (sometimes called Damastes), who had two beds that he would offer to travellers. If the traveller was too tall to fit in the bed, Procrustes would cut off their limbs; if they were too short, he would stretch them until they fit. Theseus killed Procrustes by putting him on one of his beds, cutting off his legs, and then decapitating him.

Arrival at Athens

After clearing the Isthmus, Theseus finally arrived at Athens. He did not, however, reveal himself to his father Aegeus immediately. Aegeus became suspicious of the stranger and consulted Medea, whom he had married after sleeping with Aethra. 

Medea realized that Theseus was the son of Aegeus, but she did not want Aegeus to recognize him. She was afraid he would choose Theseus as his heir over her own son. Medea therefore tried to trick her husband into killing Theseus. 

In some stories, Medea convinced Aegeus to send Theseus to slay the monstrous Bull of Marathon, hoping that the bull would kill him first. In other stories, Medea tried to poison Theseus. But Aegeus recognized Theseus by the sword he was carrying (the sword he had left with Aethra at Troezen) and stopped him from drinking the poison. Medea fled into exile.

Medea was not the only threat to Theseus’ standing in Athens. The sons of Aegeus’ brother Pallas (often called the Pallantides) had hoped to inherit the throne if their uncle Aegeus died childless. According to some sources, the sons of Pallas ambushed or rebelled against Theseus and Aegeus. This attempt failed, however, and after Theseus killed the sons of Pallas he was secured as the heir to the throne of Athens.4

The Minotaur

During Aegeus’ reign, the Athenians were forced to send a regular tribute of fourteen youths (seven boys and seven girls) to Minos, the king of the island of Crete. This was reparation for the murder of Minos’ son Androgeus in Athens several years before. When the fourteen tributes reached Crete, they were fed to the Minotaur, a terrible bull-man hybrid born from an affair between a divine bull and Minos’ wife Pasiphae: 

A mingled form and hybrid birth of monstrous shape, ...

Two different natures, man and bull, were joined in him.5

The Minotaur was imprisoned in the Labyrinth, a giant maze built by the Athenian architect Daedalus. None of the tributes who were sent into the Labyrinth ever made it out. 

Soon after his arrival in Athens, Theseus sailed off as one of the fourteen tributes dedicated to the Minotaur. According to some traditions, Theseus actually volunteered to go to Crete, vowing that he would kill the Minotaur and bring an end to the terrible tribute once and for all.6 The ship on which he and the other tributes embarked had a black sail; before the ship left for Crete, Aegeus made Theseus swear that if he managed to return alive he would have the black sail changed to a white one. 

At Crete, Minos’ daughter Ariadne fell in love with Theseus and agreed to help him kill the Minotaur if he would take her with him to Athens. Before Theseus entered the Labyrinth, Ariadne gave him a ball of thread. Theseus unravelled the thread as he moved through the Labyrinth, killed the Minotaur, and found his way out of the Labyrinth by following the thread back to the exit. 

Theseus and Ariadne then escaped from Crete with the other tributes.

On their journey back to Athens, Theseus stopped at the island of Naxos. There are different versions of what happened to Ariadne there. According to some, Theseus simply abandoned her. Another well-known story, however, claims that Dionysus fell in love with Ariadne while she was on Crete and carried her off for himself. In any case, Theseus arrived at Athens without Ariadne.7

Whether distracted by the loss of Ariadne or for some other reason, Theseus forgot to raise the white flag as he came back to Athens. Aegeus, who was watching from a tower, saw the black flag and thought that his son had died. Overcome by grief, Aegeus killed himself by leaping into the sea (this is the origin, according to the Greeks, of the name of the “Aegean Sea”). Theseus arrived to find his father dead and so became king of Athens.

The Amazons

Like many heroes of Greek mythology, Theseus waged war with the Amazons. The Amazons were a fierce race of warrior women who lived near the Black Sea or the Caucasus. Their queens were said to be the daughters of the war god Ares

While among the Amazons, Theseus fell in love with their queen, Antiope (sometimes called Hippolyta),8 and carried her off with him to Athens. The Amazons then attacked Athens in an attempt to get Antiope back. In some versions of the myth, the Amazons laid waste to the countryside of Attica and only left after Antiope was accidentally killed in battle.9 

In other versions, Theseus tried to abandon Antiope so that he could marry Phaedra, a princess from Crete; when the jilted Antiope tried to stop the wedding, Theseus killed her himself.10 In all versions of the story, however, Theseus finally managed to drive the Amazons away from Athens after the death of Antiope, though only after Antiope had given him a son named Hippolytus.

Hippolytus

After the death of Antiope, Theseus married Phaedra, the daughter of the Cretan king Minos and thus the sister of his former lover Ariadne. Phaedra bore Theseus two children, Acamas and Demophon. 

Eventually, however, Phaedra fell in love with Hippolytus, the son of Theseus’ first wife, Antiope. Phaedra tried to convince Hippolytus to sleep with her. When he refused, Phaedra tore her clothing and falsely claimed that Hippolytus had raped her. Theseus was furious and prayed to Poseidon that Hippolytus might be punished. 

Poseidon, unfortunately, heard Theseus’ prayer and sent a bull from the sea to charge Hippolytus as he was riding his chariot near the coast. Hippolytus’ horses were frightened; he lost control of the chariot, became entangled in the reins, and was trampled to death. Theseus discovered his son’s innocence too late; Phaedra, ashamed and guilty, hanged herself.11 

Abduction of Helen and Persephone

Theseus took part in several other adventures. Some sources include him among the Argonauts who sailed with Jason to retrieve the Golden Fleece, or with the heroes who took part in the Calydonian Boar Hunt. 

In many of these adventures, Theseus was accompanied by his best friend Pirithous, the king of the Lapiths of northern Greece. In one famous tradition, Theseus and Pirithous both vowed to marry daughters of Zeus. Theseus chose Helen, and Pirithous helped him abduct her from her father Tyndareus’ home in Sparta. 

Pirithous then chose Persephone as his bride, even though she was already married to Hades. Theseus left Helen in the care of his mother, Aethra, while he and Pirithous went to the Underworld to abduct Persephone. Predictably, this did not end well. Theseus and Pirithous were caught trying to abduct Persephone and trapped in the Underworld. 

While Theseus was away from Athens, Helen’s brothers, Castor and Polydeuces, retrieved her and took Aethra prisoner. Meanwhile, Theseus was eventually rescued from Hades by Heracles, but Pirithous remained trapped in eternal punishment for his impiety (in the most common version of the story).12 When Theseus returned to Athens, he found that Helen was gone and that his mother had become her slave in Sparta.

Athenian Government and Death

Theseus was said to have been responsible for the synoikismos (“dwelling-together”), the political and cultural unification of the region of Attica under the rule of the city-state of Athens. In later times, some Athenians even traced the origins of democratic government to Theseus’ rule, even though Theseus was a king. Theseus was always seen as an important founding figure of Athenian history.

As an old man, Theseus fell out of favor in Athens. Driven into exile, he came to Scyrus, a small island in the Aegean Sea. It was in Scyrus that Theseus died. In some stories, he was thrown from a cliff by Lycomedes, the king of Scyrus. In 475 BCE, the Athenians claimed to have identified the remains of Theseus on Scyrus and brought them back to be reinterred in Athens.

Worship

Festivals and/or Holidays

The festival of Theseus, called the Theseia, was celebrated in Athens in the autumn. It was presided over by the Phytalidae, the hereditary priests of Theseus. The Phytalidae were said to have been the direct descendants of the fourteen tributes Theseus saved when he killed the Minotaur.13 Little else is known of the festivals or worship of Theseus.

Temples

The hero-cult of Theseus was almost certainly concentrated solely in the city of Athens. The main sanctuary of Theseus, the Theseion, may have existed as early as the sixth century BCE.14 It was most likely located at the center of Athens, in the vicinity of the Agora. Though the Theseion was probably the main center of Theseus’ hero-worship, little else is known about it, and there is still virtually no archaeological evidence of it. There were likely other sanctuaries of Theseus in Athens by the fourth century BCE.

Pop Culture

Theseus has had a rich afterlife in modern popular culture. The 2011 film Immortals is loosely based on the myth of Theseus and the Minotaur; Theseus is portrayed by Henry Cavill. Theseus also features in the miniseries Helen of Troy (2003), in which he kidnaps Helen with his friend Pirithous. 

The myths of Theseus are also retold in many modern books and novels. Mary Renault’s critically acclaimed The King Must Die (1958) is a historicized retelling of Theseus’ early life and his battle with the Minotaur; its sequel, The Bull from the Sea (1962), deals with Theseus’ later career. The myth of Theseus and Antiope is also reimagined in Steven Pressfield’s novel Last of the Amazons (2002). Jorge Luis Borges’ short story The House of Asterion (published in Spanish in 1947) presents an interesting variation on the myth of the Minotaur, told from the perspective of the Minotaur rather than Theseus. 

The myth of Theseus inspired Suzanne Collins’ The Hunger Games trilogy (2008–2010).

Primary Sources

As the most important hero of one of the most important ancient Greek cities, Theseus was well attested in the primary sources. Still, many early works that recounted the myth of Theseus are lost. One of the most important examples is the Theseid, a sixth-century BCE Athenian epic that recounted Theseus’ exploits in detail. The Athenians also wrote many tragedies concerning Theseus’ career which no longer survive.

Greek

  • Homer: Theseus is named among the dead Greek heroes in the Underworld in Book 11 of the Odyssey (eighth century BCE).

  • Sophocles: Theseus is a major character in Sophocles’ Oedipus at Colonus (ca. 406 BCE), welcoming the dying Oedipus into Athens and guaranteeing his burial.

  • Euripides: Euripides’ Hippolytus (428 BCE) tells the story of Phaedra’s illicit passion for Hippolytus and Hippolytus’ subsequent death. Theseus also plays an important role in Euripides’ Suppliants (ca. 423 BCE), where he helps retrieve and bury the bodies of the Argive heroes killed in the failed war of the “Seven against Thebes.”

  • Callimachus: Theseus is the most important character of the third-century BCE poet Callimachus’ Hecale, an epyllion (mini-epic) that told the story of Theseus’ stay with the old widow Hecale on his way to fight the Bull of Marathon. Unfortunately, this poem only survives in fragments. 

Theseus’ return from Crete after killing the Minotaur is also mentioned in Callimachus’ Hymn 4. Theseus would have likely featured in some of Callimachus’ many other poems, such as the Aetia, but these are lost.

  • Strabo, Geography: An important 1st-century BCE resource for many local Greek myths and customs.

  • Plutarch: Life of Theseus is a first-century CE biography of Theseus from Plutarch’s collection Parallel Lives, which compared pairs of Greek and Roman figures. Theseus was paired with the Roman founding hero Romulus.

  • Pausanias, Description of Greece: A second-century CE travelogue and one of our most important sources for local myths and customs.

Roman

  • Catullus: Catullus’ Poem 64 (mid-first century BCE) includes a highly elegiac account of Theseus’ abandonment of Ariadne on the deserted island of Naxos.

  • Ovid: Theseus’ major exploits, including his battle with the Minotaur and his involvement in the Calydonian Boar Hunt, are treated in Book 8 of Ovid’s famous epic the Metamorphoses (ca. 8 CE). 

The fourth and tenth letters of Ovid’s epistolary Heroides are also addressed to Theseus: in Heroides 4, Phaedra confesses her infatuation with Theseus’ son Hippolytus, and in Heroides 10, Ariadne reproaches Theseus for deserting her on Naxos.

  • Seneca: Seneca’s Phaedra (first century BCE/first century CE), like Euripides’ Hippolytus, deals with the incestuous love triangle of Theseus, his wife Phaedra, and his son Hippolytus.

Mythological Handbooks (Greek and Roman):

  • Diodorus of Sicily, Library of History: A work of universal history, covering events from the creation of the cosmos to Diodorus’ own time (mid-first century BCE). The myths of Theseus are described in Book 4.

  • Apollodorus, Library and Epitome: A mythological handbook from the first century BCE or the first few centuries CE. The myths of Theseus are treated in Book 3 of the Library and in the beginning of the Epitome.

  • Hyginus, Fabulae: A Latin mythological handbook (first or second century CE) that includes sections on the myths of Theseus.
