Heracles, known to the Romans as Hercules, is the greatest of the Greek heroes, a demigod of immense strength whose twelve labors, tragic madness, and eventual deification form one of the most enduring cycles in world mythology. His story is not a single narrative but a web of episodes told across centuries, with the earliest references in Homer’s Iliad and Hesiod’s Theogony (c. 8th–7th century BC), and the most complete surviving account in the Library of Apollodorus (c. 1st–2nd century AD).
Birth and Divine Conflict
Heracles was the son of Zeus and Alcmene, a mortal princess of Tiryns. Zeus, having taken the form of Alcmene’s husband Amphitryon, fathered the hero on a night that he made three times longer. When Alcmene gave birth, Zeus declared that the child born that day of his bloodline would rule over the Argolid. Hera, Zeus’s wife, delayed Alcmene’s labor and caused the early birth of Eurystheus, the son of Sthenelus (another Perseid), who thus became king and Heracles’ lifelong master. In a separate tradition, Hera sent two serpents to kill the infant in his cradle, but Heracles strangled them with his bare hands—a story told by Pindar and later visual artists.
The name Heracles, meaning “Glory of Hera,” was given to the child to appease the goddess, though it did little to soften her hostility. This divine antagonism is the engine of the hero’s entire myth: Hera’s persecution drives him to madness, to servitude, and ultimately to the labors that define him.
The Madness and the Labors
The pivotal event in Heracles’ mortal life came when he was a young married man with children. Hera drove him into a fit of madness, and in that state he killed his wife Megara and their children. On recovering, Heracles consulted the oracle at Delphi, who instructed him to serve King Eurystheus of Tiryns for twelve years and to perform whatever tasks were set for him. In return, he would gain immortality.
Eurystheus imposed twelve labors, each seemingly impossible. They are traditionally listed in this order:
- Slay the Nemean Lion and bring back its hide.
- Slay the Lernaean Hydra, a many-headed serpent that grew two heads for each one cut.
- Capture the Ceryneian Hind, a sacred deer of Artemis, alive.
- Capture the Erymanthian Boar alive.
- Clean the Augean Stables in a single day, by diverting two rivers through them.
- Drive away the Stymphalian Birds, man-eating birds with bronze beaks.
- Capture the Cretan Bull alive.
- Steal the Mares of Diomedes, which were fed on human flesh.
- Obtain the girdle of Hippolyta, queen of the Amazons.
- Capture the cattle of Geryon, a three-bodied giant, from the far west.
- Fetch the golden apples of the Hesperides, guarded by a dragon.
- Bring Cerberus, the three-headed dog of Hades, up from the underworld.
Each labor has its own sub-myths. For the Hydra, Heracles was aided by his nephew Iolaus, who cauterized the necks to prevent regrowth; because of this help, some versions say the labor was not counted. For the Augean Stables, Heracles demanded payment from Augeas, and when the king refused, Heracles later killed him—an act that also disqualified the labor in some accounts. The apples of the Hesperides required Heracles to hold up the sky while Atlas fetched them, a trick that shows the hero’s wit as much as his strength.
Other Adventures and the Trojan War
The labors were not the whole of Heracles’ story. He took part in the voyage of the Argonauts, though he left early after his lover Hylas was abducted by nymphs. He fought against the Amazons, killing Hippolyta in some versions after a misunderstanding. He also sacked Troy, killing King Laomedon because the king had refused to pay him for rescuing his daughter Hesione from a sea monster—an event that set the stage for the later Trojan War, since the surviving prince Priam was Laomedon’s son.
Heracles also fought the river god Achelous for the hand of Deianira, a wrestling match in which Achelous turned into a snake and a bull. This marriage would lead to the hero’s death.
Death and Apotheosis
Heracles’ death came from a poisoned garment. On a journey with Deianira, they crossed a river with the help of the centaur Nessus, who tried to rape Deianira. Heracles shot him with a poisoned arrow. As he died, Nessus told Deianira to collect his blood and use it as a love charm if Heracles ever strayed. Later, when Heracles showed interest in another woman, Deianira soaked a robe in the blood and sent it to him. The blood was poisoned by the Hydra’s venom from the arrow, and the robe burned Heracles’ skin.
In agony, Heracles built a funeral pyre on Mount Oeta and asked a passerby, Poeas, to light it. As the flames consumed his mortal body, Zeus carried him to Olympus, where he was reconciled with Hera and married Hebe, the goddess of youth. This apotheosis—the transformation of a mortal hero into a god—is unique among Greek heroes and is attested as early as Homer’s Odyssey, where Odysseus sees Heracles’ shade in the underworld while his real self dwells among the gods.
Heracles vs. Hercules: Greek and Roman Versions
The Roman Hercules is a distinct figure from the Greek Heracles, though the Romans adopted the Greek myths wholesale. The Roman Hercules was more of a patron of strength and victory, celebrated in triumphal processions, and his cult was widespread among soldiers and merchants. The Romans also added local legends, such as Hercules’ visit to the site of Rome, where he killed the giant Cacus who had stolen his cattle. This story, told by Virgil in the Aeneid, ties the hero to the founding of Rome. In art, the two are often indistinguishable, but the Roman version tends to emphasize his civilizing role over his tragic madness.
Cultural Significance and Interpretations
Heracles was not just a myth; he was a religious figure with cults across Greece and Italy. His suffering and triumph were seen as a model of endurance, and his labors were interpreted allegorically by later philosophers. The Stoics, in particular, saw him as an example of virtue overcoming hardship. In modern times, Heracles has been read as a symbol of masculinity, of the human struggle against impossible odds, and even as a proto-ecological figure in his cleaning of the Augean stables. His image appears in art from ancient vases to Renaissance paintings to contemporary film, making him one of the most recognizable figures in Western culture.
Frequently Asked Questions
Why did Heracles have to perform the twelve labors?
Because he killed his wife and children in a fit of madness sent by Hera. To atone, the Delphic oracle told him to serve King Eurystheus for twelve years and complete whatever tasks he was given. The labors were set by Eurystheus, who hoped Heracles would die attempting them.
Was Heracles a god or a mortal?
He was a demigod—the son of Zeus and a mortal woman—so he was born mortal. After his death on the pyre, Zeus made him immortal and brought him to Olympus. This made him unique among Greek heroes, who typically died and went to the underworld.
What was the hardest labor?
There is no single answer in the sources. Many ancient writers considered the twelfth labor, bringing Cerberus from the underworld, the most dangerous because it required descending into Hades. Others point to the Nemean Lion, whose hide was impervious to weapons, or the Hydra, which required help to defeat.
Did Heracles have any children?
Yes, many. With Megara he had several children, whom he killed. With Deianira he had a son, Hyllus, who played a role in his death and burial. He also had many other children by various women, collectively known as the Heracleidae, who later claimed the right to rule in Greece.
Why is Heracles called Hercules in Roman mythology?
The Romans adopted Greek myths and Latinized the name. “Heracles” became “Hercules” in Latin. The Roman version also had its own local stories, like the battle with Cacus, and a stronger emphasis on his role as a civilizing hero.
