The Universal Hero: Heracles / Hercules
The Greatest Hero of the Ancient World
Heracles was the most celebrated hero in the ancient world — not merely a Greek figure but one who was absorbed into Roman religion and eventually worshipped as a god in both cultures. His story begins with the most dramatic possible birth. Zeus, king of the gods, fathered Heracles on a mortal woman, Alcmene, by disguising himself as her husband Amphitryon. Hera, Zeus’s divine wife, was furious at this act of infidelity and persecuted Heracles throughout his life. She sent two serpents to kill him in his cradle, but the infant Heracles strangled them both — his first display of the superhuman strength that defined him.
The name “Heracles” was said to mean “glory of Hera” — a bitterly ironic name for a hero tormented by the goddess. Yet it was Hera’s persecution that ultimately made him great. By driving him to madness and causing him to kill his own wife and children, Hera inadvertently set in motion the series of tasks that would become his most famous achievement: the twelve labours.
The twelve labours of Heracles, assigned by King Eurystheus of Tiryns as penance for killing his family: (1) the Nemean Lion; (2) the Lernaean Hydra; (3) the Ceryneian Hind; (4) the Erymanthian Boar; (5) the Augean Stables; (6) the Stymphalian Birds; (7) the Cretan Bull; (8) the Mares of Diomedes; (9) the Girdle of Hippolyta; (10) the Cattle of Geryon; (11) the Apples of the Hesperides; (12) Cerberus from the Underworld. All twelve were carved in relief on the metopes of the Temple of Zeus at Olympia.
The Labours on the Temple of Zeus at Olympia
The Temple of Zeus at Olympia was one of the great religious monuments of ancient Greece, completed around 457 BC. Around the exterior, at the top of the walls in the space below the roof (the metopes), were twelve sculpted reliefs depicting each of the twelve labours of Heracles. These carvings were not merely decorative: they were placed on the holiest temple at the most important religious sanctuary in Greece, making a clear statement that Heracles’s deeds were divinely sanctioned. The sculptures show him in action — wrestling the Nemean Lion; supporting the heavens while Atlas retrieved the golden apples; bringing Cerberus up from the underworld. Each metope told the story of a specific labour with crisp, Classical-period carving. The placement of Heracles’s myths on Zeus’s own temple at Olympia connected the hero directly to his divine father and to the Olympic Games, which Heracles himself was said to have founded.
The Homeric Hymn to Heracles the Lion-Hearted
The Homeric Hymn to Heracles the Lion-Hearted is one of the prescribed literary sources and provides an important perspective on how the Greeks viewed this hero. The hymn is brief but dense with meaning. It opens by identifying Heracles as the son of Zeus and Alcmene, emphasising his divine father and mortal mother — the combination that makes him exceptional. It describes him as “lion-hearted” (the Greek word is literally “of great spirit”), wandering the earth performing mighty deeds. The hymn ends by celebrating the fact that Heracles was eventually received onto Olympus as a god, living among the immortals with Hebe (the goddess of youth) as his wife. This arc — from mortal suffering to divine reward — is the central message of the Heracles myth.
The Homeric Hymn to Heracles shows that even in antiquity he was regarded as having achieved apotheosis — transformation from mortal hero to god. This made him unique among Greek heroes and explained his widespread worship across both Greece and Rome.
Heracles at Olympia and the Olympic Games
Ancient tradition held that Heracles himself founded the Olympic Games. One version of the story said that after completing the fifth labour (cleansing the Augean Stables by diverting two rivers through them), Heracles laid out the sacred precinct at Olympia and established the games in honour of his father Zeus. This tradition gave the games a legendary prestige and divine connection. The Olympic Games were held every four years and were by far the most prestigious athletic contest in the Greek world: a victory at Olympia brought kleos (glory) that endured for generations. The link between Heracles and Olympia — reinforced by the twelve labour metopes on the Temple of Zeus — meant that every victor at the games was walking in the footsteps of the greatest hero.
The Romans called him Hercules and gave him an important role in Roman foundation mythology. In Virgil’s Aeneid (8.154–279), the hero Aeneas arrives at the site of future Rome and finds that the people there already honour Hercules with an annual festival. They tell Aeneas the story of Hercules’s fight with the monstrous Cacus, a fire-breathing son of Vulcan who had stolen Hercules’s cattle and dragged them backwards into his cave to hide his tracks. Hercules tracked him down, tore open the cave, and killed him. By placing this story at the future site of Rome, Virgil establishes Hercules as a protector of the Roman people long before Rome existed — the hero clears the land of monsters so that civilisation can take root.
Ovid’s Metamorphoses (Books 8–9) tells the story of Hercules’s battles with the river-god Achelous (who competed with Hercules for the hand of Deianeira), the killing of the centaur Nessus, and the hero’s agonising death. The centaur Nessus, wounded by a poisoned arrow, tricked Deianeira into keeping his blood-soaked tunic, telling her it was a love charm. Years later she sent it to Hercules; the poison burned through his skin and he could not die. In agony, Hercules built his own funeral pyre on Mount Oeta and asked to be burned alive. As the fire consumed his mortal body, he was taken up to Olympus and made immortal. Even in the Roman version, the story ends with apotheosis.
Heracles in Art
Heracles is one of the most immediately recognisable figures in Greek and Roman art because of his consistent attributes: the Nemean lion-skin worn as a cloak, and the wooden club he carried as a weapon. These appear on vases, relief carvings, gems, and large-scale sculpture across several centuries. On black-figure and red-figure pottery, the most common scenes show him wrestling the Nemean Lion (his lion-skin not yet won), fighting the Hydra, battling centaurs, or driving the cattle of Geryon. The Temple of Zeus metopes at Olympia show him in action in the Classical marble tradition, and Roman copies of Hellenistic bronzes often show a tired, muscular figure leaning on his club after his labours — a subject that later became popular as a way of exploring heroic exhaustion alongside strength.
Most Greek heroes were local — tied to a specific city, family or region. Theseus belonged to Athens; Achilles to Phthia and Troy; Perseus to Argos. Heracles was different: his twelve labours took him across the known world, and his myths spread wherever Greek (and later Roman) culture reached. He was worshipped across Greece and became one of the most important protective deities in Rome. His story had universal appeal: it addressed suffering, perseverance, the possibility of redemption, and the prospect of immortality as the reward for an exceptional life. Both cultures saw in him a model of the hero who earns divine status through deeds, not birth alone. The Stoic philosophers later made him a symbol of virtue achieved through hardship, and his myth influenced ideas of heroism in European culture for centuries.
