Greek heroes occupy the central place in the mythology of ancient Greece. They were the bridge between the world of gods and the world of mortals, often born of one divine parent and one mortal parent, and their legends defined what it meant to be brave, cunning, doomed, and divine. The great hero cycles of Heracles, Achilles, Odysseus, Perseus, Theseus, and Jason form the heart of Greek epic literature, and their stories were told, retold, painted, sculpted, and dramatized throughout the ancient world.
How to Read This Guide
The Greek word hērōs (ἥρως), translated here as “hero,” had a more restricted sense in the archaic period than it does in English. A hērōs in Homer is a figure of the aristocratic past, a warrior or king whose cult survived at a particular tomb. The Achilles of the Iliad is a hērōs; the Homeric Odysseus is a hērōs; the Heracles of the Twelve Labors is a hērōs; the Theseus of Plutarch’s Life of Theseus is a hērōs; the Perseus of Apollodorus’ Bibliotheca is a hērōs. The English word hero has expanded the meaning (and a Greek hērōs does not necessarily include a tragic element, the way an English hero does), but the Greek hērōs is the older and stricter sense, and the one used on this page.
The Greek tradition distinguishes the mortal hero from the immortal god in a way that the modern reader may not appreciate. The Greek hero is a mortal — even Heracles, who is later deified, is a mortal in the standard tradition — and the hero’s mortality is the source of his tragic dimension. The hērōs knows he is going to die. The gods are immortal and know they are not. The hero’s heroism is the working out of his mortality, and the working out is what the great hero cycles are about.
The four great Greek sources for the hero cycles are Homer’s Iliad and Odyssey (8th century BCE, the canonical hero cycles), Hesiod’s Catalogue of Women (lost, but summarised in Apollodorus, the source of the older versions of the myths of the heroes), the Epic Cycle (lost, summarised in Proclus’ Chrestomathy, the source of the Cypria, Aethiopis, Little Iliad, and Nostoi), and Apollodorus’ Bibliotheca (first or second century BCE, the encyclopaedic version, the most useful single ancient source for the modern reader). The standard scholarly reading of the hero cycles is in the Cambridge Companion to Greek Mythology (2014) and in the Cambridge Companion to Homer (2004). For the modern reception, see our guide to Greek mythology in modern culture.
The reader who wants a quick start should begin with the Iliad (Lattimore or Fagles translation), then with the Odyssey (the same), then with the Odysseus and Achilles profiles below. The reader who wants the comprehensive picture should read the profiles below in order: Heracles, Perseus, Theseus, Jason, Achilles, Odysseus, and the Trojan War guide for the central hero cycle.
The Greek word for hero, heros, did not originally mean a virtuous protagonist. It referred to a powerful dead figure who was worshipped locally and could influence the living. The heroic age in Greek myth is a transitional era between the age of the gods and the age of mortals, and its heroes are characterized by extraordinary strength, divine favor, dangerous quests, and almost always, a tragic or mysterious death.
The Nature of the Greek Hero
Greek heroes share certain common features, although they vary enormously in temperament and story. Most were demigods, the offspring of a god, usually Zeus, and a mortal parent. Heracles was the son of Zeus and Alcmene. Achilles was the son of the sea-nymph Thetis and the mortal Peleus. Perseus was the son of Zeus and Danaë. Theseus had a divine father in Poseidon. Jason’s patron was Hera.
The hero’s life was rarely peaceful. From birth, they were often marked for greatness by omens or prophecies, and from childhood they faced attempts on their lives. Heracles was nearly killed as an infant by Hera, who sent serpents to his cradle. Achilles was dipped in the river Styx as a baby by his mother, holding him by the heel where the waters did not touch. Odysseus was famous even as a young man for his cleverness and his ability to escape danger.
The hero’s defining quest, or set of quests, typically involved confronting a monster, retrieving a magical object, or completing a seemingly impossible task. The Twelve Labors of Heracles are the most famous example. The quest of Jason for the Golden Fleece is another. The voyage of Odysseus home from Troy is a third. The slaying of Medusa by Perseus, the defeat of the Minotaur by Theseus, and the rescue of Andromeda from a sea-monster were all classic hero-quests.
The hero’s reward was often mixed. Some heroes, like Heracles, eventually achieved apotheosis, becoming gods themselves. Most, however, met violent or tragic ends. Achilles died at Troy, struck in the heel by Paris’s arrow. Odysseus struggled for ten years to return home. Perseus accidentally killed his grandfather Acrisius with a discus, fulfilling the prophecy he had been trying to escape, and afterwards exchanged kingdoms with Megapenthes, king of Tiryns, ruling there for the rest of his life. Theseus was exiled from Athens and died in disgrace. Jason was crushed by the rotting beam of the Argo. The heroic life, in Greek myth, was both glorious and bitter.
Heracles: The Greatest of Heroes
Heracles was the greatest of all Greek heroes, a figure so central to Greek religion that he was worshipped as a god in many places. He was the son of Zeus and the mortal Alcmene, and he was hated from birth by Hera, Zeus’s wife, who sent two serpents to kill him in his cradle. The infant strangled them both.
The defining quest of Heracles was the Twelve Labors, a series of seemingly impossible tasks assigned to him by King Eurystheus as penance for killing his family in a madness sent by Hera. The Labors included slaying the Nemean Lion, the Lernaean Hydra, and the Stymphalian Birds; capturing the Ceryneian Hind and the Erymanthian Boar; cleaning the Augean Stables in a single day; capturing the Cretan Bull; stealing the Apples of the Hesperides; capturing Cerberus, the three-headed dog of the underworld; and obtaining the Girdle of Hippolyta and the Cattle of Geryon.
Beyond the Twelve Labors, Heracles had countless other adventures. He joined the Argonauts, sacked Troy twice, defeated the Giants, and fathered dozens of children. His death came when his wife Deianira, deceived by the centaur Nessus, smeared his cloak with poisoned blood, and Heracles, wearing it, was burned alive. He ascended to Olympus and was given Hebe, the goddess of youth, as his wife.
For a full treatment, see our profile of Heracles.
Achilles: The Wrathful Hero of Troy
Achilles was the greatest warrior of the Greeks at Troy, the central figure of Homer’s Iliad, and the archetypal tragic hero. He was the son of the sea-nymph Thetis and the mortal king Peleus of Phthia, and his destiny was foretold by prophecy: he would either live a long, obscure life, or a short, glorious one, and die young at Troy. His mother chose glory for him.
Achilles is the hero of wrath. The Iliad opens with his quarrel with Agamemnon, the leader of the Greek forces, over a captive woman. Achilles withdraws from the fighting, and the Greeks begin to lose. When his beloved companion Patroclus is killed by Hector, Achilles returns to battle in a frenzy of grief, killing Hector and dragging his body behind his chariot. He eventually returns Hector’s body to Priam, the Trojan king, for proper funeral rites.
Achilles is famously vulnerable in his heel, the only part of his body not immersed in the river Styx when his mother dipped him as a baby. He was killed at Troy by Paris, who shot an arrow, guided by Apollo, into his heel. The famous “Achilles’ heel” has come to mean any critical weakness.
Odysseus: The Cunning Man of Many Wiles
Odysseus was the king of Ithaca, a small island in the Ionian Sea, and the hero of Homer’s Odyssey, the second great epic of the Trojan cycle. He was famous for his cunning, his eloquence, and his ability to devise plans where brute force failed. It was Odysseus who devised the Trojan Horse, the trick that ended the ten-year war.
After Troy fell, Odysseus’s journey home took ten years. He and his crew encountered the Cyclopes, the cannibalistic Laestrygonians, the sorceress Circe who turned men into pigs, the Sirens whose song lured sailors to their deaths, the monsters Scylla and Charybdis, and the underworld itself, where he consulted the prophet Tiresias. Throughout, he used his wits to survive, sometimes at great cost to his men.
The Odyssey ends with Odysseus returning to Ithaca, finding his wife Penelope plagued by suitors, killing them, and reasserting his kingship. Odysseus has become a symbol of endurance, resourcefulness, and the long journey home.
Perseus: The Gorgon-Slayer
Perseus was the son of Zeus and the mortal princess Danaë. He is best known for slaying Medusa, one of the three Gorgon sisters, whose gaze could turn onlookers to stone. With divine aid, Athena gave him a polished shield to use as a mirror, and Hermes gave him winged sandals to flee. Perseus cut off Medusa’s head without looking at her directly, and from her blood sprang the winged horse Pegasus and the giant Chrysaor.
After killing Medusa, Perseus used her head as a weapon to rescue the princess Andromeda from a sea-monster, and the two were married. They later returned to his homeland, where Perseus accidentally killed his grandfather Acrisius with a discus throw, fulfilling an old prophecy. He gave the Gorgon’s head to Athena, who mounted it on her aegis.
Theseus: Founder of Athens
Theseus was the legendary founder-hero of Athens, the city that would become the cultural heart of ancient Greece. He was the son of Aegeus, king of Athens, and either Aethra or, in some versions, Poseidon.
Theseus’s most famous adventure was the slaying of the Minotaur, a half-man, half-bull creature that lived in the Labyrinth of Crete. With the help of Ariadne, the daughter of King Minos, who gave him a ball of thread to find his way out, Theseus entered the Labyrinth, killed the Minotaur, and escaped. He returned to Athens, but in a moment of forgetfulness or grief, he forgot to change his sails from black to white, and his father Aegeus, seeing black sails, threw himself into the sea in despair. That sea is now called the Aegean.
Theseus also fought the Centaurs, joined the Argonauts, kidnapped the young queen of the Amazons, and was briefly a king of Athens. He is the founder of the Athenian democracy in myth, having unified the various townships of Attica into a single city-state.
Jason and the Argonauts
Jason was the prince of Iolcos in Thessaly, sent on a quest to retrieve the Golden Fleece from the distant land of Colchis. The fleece, the golden wool of a sacred ram, hung in a grove guarded by a dragon. Jason assembled a crew of heroes, the Argonauts, named for their ship, the Argo, and set sail on a series of adventures.
The Argonauts included Heracles, Theseus, Orpheus, the seer Idmon, the helmsman Tiphys, and the twins Castor and Pollux. They passed through the Clashing Rocks, fought the birds of Stymphalus, encountered the women of Lemnos, and consulted the prophet Phineus.
In Colchis, Jason won the fleece with the help of Medea, the local princess and a powerful sorceress, who fell in love with him. They fled Colchis together, but their marriage ended tragically when Jason abandoned Medea for a more politically advantageous bride. Medea took terrible revenge, killing their children and her rival. Jason’s death came when the rotting beam of the Argo fell on him as he slept.
The Heroic Age and the Trojan War
The heroic age culminated in the Trojan War, the great ten-year conflict in which most of the heroes of the previous generation died. The war gathered the heroes of Greece, including Achilles, Odysseus, Ajax the Greater and Ajax the Lesser, Diomedes, Nestor, Idomeneus, and the Spartan brothers Menelaus and Agamemnon, on the Greek side, and the brothers Hector, Paris, and Deiphobus on the Trojan side, along with allies like the Ethiopian king Memnon and the Amazons led by Penthesilea.
The Trojan War marked the end of the heroic age. Of the great Greek heroes, only Odysseus returned home after a long journey. Most of the others died in battle, on the return journey, or shortly after reaching home. Their descendants would form the new generation of myth and, eventually, the historical rulers of Greek city-states.
Hero Cults in Ancient Greece
Unlike gods, who were worshipped in panhellenic cults, heroes were typically worshipped at local sites, often their supposed tombs. Hero cults were important features of Greek religion. Cities competed to claim the burial of famous heroes, and oracle sites often claimed the bones of heroes brought from elsewhere.
Heracles was worshipped as a hero and as a god. His cult was one of the most widespread in Greece, with major sites at Marathon, Thebes, and the Cynosarges in Athens. Theseus was worshipped in Athens, and the bones he was said to have brought from Scyros were interred in a temple at the center of the city. Achilles was worshipped on the White Island near Troy, and his cult was so strong that Alexander the Great visited it before his Persian campaign.
The Legacy of Greek Heroes
The Greek heroes are the original action heroes. Their stories have been told and retold in every medium for three thousand years. The labors of Heracles inspired the depictions of the labors of Samson in the Hebrew Bible, the labors of St. Patrick in Christian hagiography, and countless works of art. The journey of Odysseus has been reimagined as Ulysses by James Joyce, as the science fiction of Arthur C. Clarke’s 2001: A Space Odyssey, and as the Coen Brothers’ film O Brother, Where Art Thou?. The Trojan War and its aftermath inspired Virgil’s Aeneid, Shakespeare’s Troilus and Cressida, and modern films from Troy to Percy Jackson.
The hero’s journey, as Joseph Campbell would later formalize it, is essentially the Greek hero cycle in narrative form. The call to adventure, the threshold crossing, the helper, the trials, the apotheosis or refusal of return, these are the structural elements of every Greek hero myth.
The Origins of Hero Worship
The cult of heroes was one of the oldest and most distinctive features of Greek religion. Unlike the gods, who were worshipped at panhellenic sanctuaries, heroes were worshipped locally, at their supposed tombs, and their cults were the focus of intense local pride. Cities competed to claim the burial of famous heroes, and the discovery of a hero’s bones could transform a city’s fortunes.
The word “hero” in Greek, heros, originally referred to a powerful dead person who was worshipped locally and who could influence the living. The hero cult was distinct from the cult of the gods, with different rituals, different sacrifices, and different expectations. Heroes were not omnipotent or omniscient like the gods; they were powerful, but limited, and they could be placated or appeased by the proper rituals.
The cult of Heracles was unique among hero cults, because Heracles was worshipped as both a hero and a god. The Spartans and the Athenians, in particular, worshipped Heracles as a god, and they offered him sacrifices as such. The cult of Heracles was one of the most widespread in the Greek world, and it is the origin of the phrase “Herculean,” meaning of extraordinary difficulty or effort.
The Heroic Cycle in Oral Tradition
The Greek hero cycle was not invented by the great poets of the Archaic period. It was the product of a long tradition of oral storytelling, going back to the Minoan and Mycenaean periods. The heroes and their stories were the common property of the Greek-speaking peoples, and they were reshaped and retold by each new generation.
The early Greek poets, including Homer and Hesiod, did not invent the stories of Heracles, Achilles, or Odysseus. They gave literary form to stories that had been told around campfires and palace hearths for centuries. The bards of the Mycenaean period, working in the oral tradition, had composed and sung epics about the heroes, and their works survived in the collective memory of the Greek people long after the fall of the Mycenaean civilization.
The transition from oral to written tradition, which occurred around 800 BCE when the Greek alphabet was adapted from Phoenician script, transformed the hero cycle. The stories could now be fixed in writing, and they could be transmitted without the variations of oral tradition. The Iliad and the Odyssey of Homer, the Theogony and Works and Days of Hesiod, and the works of the other early poets became the canonical versions of the hero cycle.
The oral-formulaic theory, developed by the American scholars Milman Parry and Albert Lord in the 20th century, holds that the Homeric epics were composed in an oral tradition, using traditional formulas and stock phrases. The bards of the oral tradition, working without the aid of writing, used these formulas to compose their poems in performance, and they could adapt the poems to the needs of their audiences. The written texts that survive are the result of a long process of composition, transmission, and editing, and they preserve the characteristic features of the oral tradition.
The Heroic Cycle and Greek Values
The Greek hero cycle is a window into the values of the Greek world. The hero embodies the aristocratic values of the warrior class: courage in battle, cunning in strategy, loyalty to friends, generosity to strangers, and the willingness to face danger and death for the sake of honor and glory. The hero is the model for the young men of the aristocracy to imitate, and the stories of the hero are the moral education of the Greek youth.
The hero is also the embodiment of the Greek sense of aretê, or excellence. Aretê is the quality that distinguishes the hero from the ordinary man, and it is the goal of every Greek to achieve aretê in their own life. The hero achieves aretê through his deeds, his courage, his cunning, and his endurance, and he is honored by the gods and by men for his achievements.
But the hero is also the embodiment of the Greek sense of hubris, or excessive pride. The hero is often guilty of hubris, and his hubris leads to his downfall. Achilles is guilty of hubris in his quarrel with Agamemnon, and his withdrawal from battle leads to the death of Patroclus. Ajax is guilty of hubris in his boast that he can escape the wrath of the gods, and he is destroyed by his own madness. Bellerophon is guilty of hubris in his attempt to fly to Olympus, and he is thrown from his horse and crippled for life.
The hero’s combination of aretê and hubris is the source of his tragedy. The hero is great, but he is not perfect, and his greatness is often his downfall. The hero is the embodiment of the human condition, the struggle to achieve excellence while avoiding the pitfalls of excessive pride.
The hero cycle has a typical structure, which has been formalized in modern times by the mythologist Joseph Campbell as “the hero’s journey.” The structure includes:
- The Call to Adventure: The hero is called to a quest, often by a divine or human messenger.
- The Crossing of the Threshold: The hero leaves the ordinary world and enters the world of the quest.
- The Trials: The hero faces a series of trials, often involving monsters, villains, or impossible tasks.
- The Apotheosis: The hero achieves a state of transcendence, often involving a confrontation with the divine.
- The Return: The hero returns to the ordinary world, transformed by the experience.
This structure can be seen in the cycle of Heracles, in the Odyssey of Odysseus, in the Argonautica of Jason, and in many other Greek hero cycles. The structure has been the model for countless works of literature, from the medieval romance to the modern novel to the Hollywood blockbuster.
The Heroic Age and Historical Memory
The heroic age of Greek myth is sometimes thought of as a historical period, a time when heroes walked the earth and performed deeds that are now the subject of myth. The Greek historians, including Herodotus and Thucydides, often treated the heroic age as a period that could be dated and studied. Herodotus, for example, dated the Trojan War to around 1250 BCE, and he believed that the heroes of the past were real historical figures.
The archaeological evidence from the late Bronze Age supports some of the Greek traditions. The city of Troy was indeed destroyed by fire around 1180 BCE, the right period for the legendary war. The city of Mycenae, the legendary home of Agamemnon, was a real and powerful city during the Bronze Age, and its ruins have been excavated. The cities of Thebes, Athens, and Iolcos, the legendary homes of Heracles, Theseus, and Jason, were also real and powerful cities during the Bronze Age.
But the historical evidence does not support the details of the myths. There is no evidence of a great Greek coalition that fought at Troy, no evidence of a wooden horse, no evidence of a Jason who sailed to Colchis in search of a golden fleece. The heroes of Greek myth are not historical figures who were later deified, but literary creations who embody the values and the anxieties of the Greek world.
The Hero as Outsider
The Greek hero is often an outsider, a figure who stands apart from the society he lives in. Heracles is the son of Zeus and a mortal woman, and he is hated from birth by Hera. Achilles is the son of a sea-nymph and a mortal king, and he chooses a short, glorious life over a long, obscure one. Odysseus is a king of a small, rocky island, and he is famous for his cunning rather than his strength. Theseus is the son of a god, but he is raised among the daughters of a foreign king, and he is sent to a foreign land to confront a foreign monster.
The hero’s outsider status is a key element of his appeal. The Greek hero is the embodiment of the values of the aristocratic warrior class, and he is the model for the young men of the aristocracy to imitate. The hero is brave, but he is also cunning, and he is willing to use his wits as well as his strength. The hero is loyal to his friends, but he is also ruthless to his enemies. The hero is the master of his fate, but he is also subject to the gods, and he must accept the consequences of his actions.
The Hero and the Divine
The relationship between the Greek hero and the gods is complex and often troubled. The hero is the son of a god, but he is also mortal, and he must die like all mortals. The hero is favored by the gods, but he is also persecuted by them, and he must endure their trials and their punishments.
Heracles is the son of Zeus, but he is persecuted by Hera from birth. Achilles is the son of the sea-nymph Thetis, but he is destined to die young at Troy. Odysseus is favored by Athena, but he is persecuted by Poseidon for blinding the Cyclops. Theseus is the son of Poseidon, but he is exiled from Athens and dies in disgrace. Jason is favored by Hera, but he is destroyed by his own ambition and his betrayal of Medea.
The hero’s relationship with the divine is a key element of his tragedy. The hero is not just a mortal man; he is a man caught between two worlds, the world of the gods and the world of mortals. The hero is the embodiment of the human struggle to rise above mortal limitations, but he is also the embodiment of the human inability to escape mortality entirely.
The Hero in the Modern World
The Greek hero has been one of the most influential figures in Western culture. The word “hero” comes from the Greek heros, and the modern concept of the hero derives from the Greek tradition. The hero is the central figure of countless works of literature, from the medieval romance to the modern novel to the Hollywood blockbuster. The hero is the embodiment of the values of courage, cunning, and endurance, and he is the model for the young people of every generation.
The modern hero is often quite different from the Greek hero. The modern hero is often an ordinary person who is forced into extraordinary circumstances, rather than a divine or semi-divine being. The modern hero is often a team player, rather than a lone individual. The modern hero is often a flawed character, who struggles with his or her own weaknesses, rather than a paragon of virtue.
But the modern hero is also indebted to the Greek tradition. The structure of the hero’s journey, the call to adventure, the trials, the apotheosis, the return, all derive from the Greek hero cycle. The values of courage, cunning, and endurance, the willingness to face danger, the ability to overcome obstacles, the loyalty to friends and to ideals, all derive from the Greek tradition.
The heroes of the modern world, from James Bond to Harry Potter to Frodo Baggins, all owe a debt to the Greek heroes. The Greek heroes continue to shape how we think about heroism, virtue, and the human condition, and the tradition of retelling them shows no sign of stopping.
