The Twelve Labours of Hercules — The Impossible Tasks

I. Why the Labours?

The Twelve Labours of Heracles (known as Hercules in Roman mythology) are the most famous series of adventures in all of Greek mythology. They were imposed as penance after Hera, queen of the gods, drove Heracles temporarily insane, causing him to kill his own wife Megara and their children. Consumed by guilt, Heracles consulted the Oracle at Delphi, which commanded him to serve King Eurystheus of Tiryns for twelve years and perform whatever tasks were demanded of him. Only then would he be purified of his crime.

Eurystheus — a weak, cowardly king who ruled only because Hera had manipulated Zeus's oath — designed each labour to be impossible. He sent Heracles against invulnerable beasts, demanded treasures guarded by dragons, and ultimately sent him into the underworld itself. Yet Heracles completed every task through a combination of superhuman strength, divine assistance, and cunning intelligence — earning his place as the greatest hero of the Greek world.

II. The Twelve Labours in Order

Labour 1: The Nemean Lion

Heracles was sent to slay the Nemean Lion, a monstrous beast whose golden fur was impervious to all weapons. Arrows bounced off its hide, and swords shattered on contact. Heracles cornered the lion in its cave, blocked one entrance, and wrestled the beast to death with his bare hands, strangling it. He then used the lion's own razor-sharp claws to skin it, and wore the impenetrable hide as armor for the rest of his life.

Labour 2: The Lernaean Hydra

The Hydra was a serpentine water monster with nine heads, living in the swamps of Lerna. When one head was cut off, two more grew in its place. Heracles enlisted his nephew Iolaus as an assistant: as Heracles severed each head, Iolaus cauterized the stump with a burning torch to prevent regrowth. The final head was immortal, so Heracles buried it under a massive boulder. He dipped his arrows in the Hydra's venomous blood, making them lethal for the rest of his adventures.

Labour 3: The Ceryneian Hind

Heracles was tasked with capturing the Ceryneian Hind — a sacred deer with golden antlers and bronze hooves, consecrated to the goddess Artemis. Since killing it would invite divine wrath, Heracles pursued the deer for an entire year across Greece, finally catching it while it slept (or, in some versions, wounding it with an arrow as it crossed a river). He apologized to Artemis, explained his penance, and promised to return the animal unharmed.

Labour 4: The Erymanthian Boar

Heracles captured alive an enormous wild boar that terrorized the slopes of Mount Erymanthos. He chased the boar through deep snow until it was exhausted, then bound it in chains and carried it back to Eurystheus, who was so terrified he hid inside a large bronze storage jar — a scene frequently depicted in ancient art.

Labour 5: The Augean Stables

King Augeas owned the largest cattle herd in Greece, and his stables had not been cleaned in thirty years. Eurystheus ordered Heracles to clean them in a single day — an intentionally humiliating task for the greatest hero alive. Heracles solved the problem with engineering rather than brute force: he diverted the courses of two rivers, the Alpheus and the Peneus, channeling them through the stables to wash away decades of filth in hours.

Labour 6: The Stymphalian Birds

A flock of man-eating birds with bronze beaks, metallic feathers they could launch like arrows, and toxic droppings infested the marshes of Lake Stymphalia. Athena gave Heracles a pair of bronze castanets (or a rattle) forged by Hephaestus. The noise startled the birds into flight, and Heracles shot them down with his Hydra-venom arrows.

Labour 7: The Cretan Bull

Heracles traveled to Crete to capture the magnificent bull that Poseidon had sent from the sea — the same bull whose union with Queen Pasiphaë produced the Minotaur. Heracles wrestled the bull into submission and brought it back to the mainland alive, where Eurystheus released it (it eventually wandered to Marathon, where Theseus later captured it again).

Labour 8: The Mares of Diomedes

King Diomedes of Thrace fed his four horses on human flesh, making them savage and uncontrollable. Heracles subdued Diomedes, fed the wicked king to his own mares, and once the horses were calm from feeding, he muzzled them and drove them back to Eurystheus.

Labour 9: The Girdle of Hippolyta

Eurystheus's daughter Admete desired the golden war girdle of Hippolyta, queen of the Amazons. Hippolyta initially agreed to give it willingly, but Hera, disguised as an Amazon warrior, spread a rumor that Heracles planned to kidnap the queen. The Amazons attacked, and in the ensuing battle, Heracles killed Hippolyta and took the girdle by force.

Labour 10: The Cattle of Geryon

Heracles journeyed to the western edge of the world to steal the red cattle of Geryon, a three-bodied giant who lived on the island of Erytheia. To reach it, Heracles erected the Pillars of Hercules (the Strait of Gibraltar), splitting a mountain in two. He killed Geryon with his arrows, slew the two-headed guard dog Orthrus, and drove the cattle all the way back across Europe to Greece.

Labour 11: The Golden Apples of the Hesperides

The golden apples of immortality grew in a divine garden at the edge of the world, guarded by the hundred-headed dragon Ladon and tended by the Hesperides, daughters of Atlas. Heracles persuaded Atlas to retrieve the apples by offering to hold up the sky in his place. When Atlas returned and tried to leave Heracles holding the heavens permanently, the hero tricked him into taking the burden back by asking him to hold it "just for a moment" while he adjusted a pad on his shoulders — then walked away with the apples.

Labour 12: The Capture of Cerberus

The final and most dangerous labour sent Heracles into the underworld itself to capture Cerberus, the three-headed hound of Hades. Heracles descended through the entrance at Taenarum, crossed the Styx, and sought permission from Hades and Persephone. Hades agreed — on the condition that Heracles use no weapons. The hero wrestled the monstrous dog into submission with his bare hands, dragged it to the surface, showed it to the terrified Eurystheus, and returned it safely to the underworld.

III. After the Labours

With the twelve labours complete, Heracles was freed from servitude and his crimes were considered atoned. But his adventures continued — he sailed with the Argonauts, sacked Troy, and fought in the Gigantomachy alongside the Olympians. His death came from the poisoned shirt of Nessus, which burned his flesh with the Hydra's venom. In agony, he built his own funeral pyre on Mount Oeta. As the flames consumed his mortal body, Zeus raised his divine essence to Olympus, where Heracles was granted full immortality — the only mortal ever to become a true Olympian god.
