Hercules and the Erymanthian Boar
At a Glance
- Central figures: Hercules, the mortal son of Jupiter, performing his fourth labor under the command of King Eurystheus of Mycenae; the centaur Pholus; the centaur Chiron.
- Setting: The wilds of Arcadia - Mount Erymanthus and the cave of Pholus on Mount Pholoe - during Hercules’ years of servitude to Eurystheus.
- The turn: Hercules stops at the cave of the centaur Pholus for food and rest, and the opening of a communal wine jar belonging to all the centaurs draws a horde of them into a violent confrontation.
- The outcome: Hercules drives off the centaurs but Pholus dies handling one of Hercules’ poisoned arrows, and the wise centaur Chiron receives an incurable wound; Hercules then tracks and captures the Erymanthian Boar alive, carrying it back to Eurystheus.
- The legacy: Eurystheus, terrified at the sight of the living boar, hid inside a bronze storage jar sunk into the ground - an image repeated on Roman pottery and reliefs, the coward king crouching in his vessel while Hercules stands above him holding the beast.
Eurystheus wanted the boar alive. Not killed, not skinned, not delivered as a carcass slung across a mule’s back. Alive and breathing and close enough that the king could look at it and know Hercules had done the impossible again. Eurystheus kept setting these tasks because he believed one of them would finally end the man Jupiter had fathered on a mortal woman. Each labor was supposed to be a death sentence dressed as an errand.
Hercules left Mycenae heading northwest toward Arcadia, where Mount Erymanthus rose above thick oak forests. Shepherds in the foothills told him the boar had been coming down from the high ridges to tear through their flocks and their fences. Its tusks had opened a man’s thigh to the bone. It moved through the undergrowth like something that owned the mountain and resented tenants.
The Cave on Mount Pholoe
Before reaching Erymanthus, Hercules climbed the lower slopes of Mount Pholoe, where the centaur Pholus kept his cave. Pholus was not like the other centaurs. He was civil, even gentle - the son of Silenus and a Melian nymph - and he welcomed Hercules at his threshold. He set out meat, roasted it over the fire for his guest though he himself ate it raw.
Hercules was thirsty. He asked for wine.
Pholus hesitated. He had wine - a massive clay jar buried half into the earth of his cave - but it did not belong to him alone. It was the common property of all the centaurs, a gift from Bacchus himself, sealed and stored for the day when they would open it together. Pholus explained this. Hercules told him to open it.
Whether Pholus obeyed out of hospitality or because one does not easily refuse a son of Jupiter, he broke the seal. The smell of the wine hit the mountain air and carried. Centaurs have sharp senses, and this was not ordinary wine. It was old and it was divine. Within minutes, centaurs began appearing at the mouth of the cave - first two, then a dozen, then scores of them, armed with rocks and pine branches torn from trees, furious that their jar had been opened without their consent.
The Fight at the Cave Mouth
They came at the cave in a rush. Hercules grabbed burning logs from the fire and hurled them into the press of bodies. When the logs ran out, he used his arrows - the ones he had dipped in the blood of the Hydra after his second labor, each point carrying poison for which there was no cure.
The centaurs broke and scattered. Some fled south toward Malea, where Poseidon - whom the Romans knew as Neptune - would later shelter them. Others ran toward Cape Malea or deep into the Peloponnesian hills. Hercules pursued them, shooting as he ran.
Chiron was among the centaurs, though he had not attacked. He was the oldest and wisest of their kind, tutor to heroes, skilled in medicine and music and the reading of stars. He had trained Hercules’ own father-by-adoption in the arts of the hunt. In the chaos of the rout, one of Hercules’ arrows struck Chiron in the knee. It was an accident - a shot that went through a fleeing centaur’s arm and lodged in Chiron behind him.
Hercules pulled the arrow out himself. He applied a salve that Chiron had taught him to make. But the Hydra’s venom was beyond any salve. The wound would not close. It would not kill Chiron either, because Chiron was immortal. He would simply suffer, endlessly, a wound that burned without consuming.
Pholus and the Poisoned Arrow
When Hercules returned to the cave, he found Pholus standing over one of the dead centaurs, examining the arrow that had killed him. Pholus pulled it from the body, turning it in his fingers, marveling that such a small thing could drop a creature that large.
The arrow slipped. It fell point-down onto his hoof, barely a scratch. Pholus was dead before he hit the ground. The Hydra’s blood did not negotiate.
Hercules buried him at the foot of the mountain. The peak above the grave would carry the centaur’s name afterward - Mount Pholoe, as it was still called in the time of the geographers who mapped the Roman provinces.
The Snow and the Boar
The boar remained. Hercules climbed Erymanthus alone now, carrying a net of heavy rope. The season was turning cold and the upper slopes held deep snow. This was what he needed.
He found the boar’s den by its tracks - wide, splayed hoofprints punched deep into the white surface. He did not approach the den. Instead he stood uphill and shouted. His voice carried across the ridge like a crack in stone.
The boar came out fast, tusks forward, breath steaming. Hercules let it charge, then drove it uphill with shouts and thrown rocks, pushing it toward a steep col where the snow had drifted to the depth of a man’s chest. The boar plunged in. Its short legs churned but found no purchase. The snow packed around its barrel chest and held it like mortar.
Hercules came down from above, dropped the net over its back, cinched the rope around its legs and tusks. The boar thrashed and screamed. He bound it tighter. Then he lifted the whole animal onto his shoulders - it weighed as much as a young bull - and began the walk back to Mycenae.
The Bronze Jar
Eurystheus had been warned by a runner that Hercules was coming, and that the boar was alive. The king did not wait at his gate. He did not arrange a reception. He climbed into a great bronze pithos - a storage jar sunk into the palace courtyard floor, the kind used for grain or oil - and pulled a lid over himself.
When Hercules arrived at the palace and held the boar over the rim of the jar, Eurystheus screamed from inside it.
Take it away. Take it out of the city. I accept the labor. Go.
Hercules set the boar down. He did not laugh, or if he did, no source records it. What the sources do record - on painted vessels, carved reliefs, and temple decorations that the Romans copied and displayed in their own cities for centuries - is the image: the hero standing, the beast slung across his arms, and the king crouching in his jar with only his hands visible above the rim, waving Hercules away. It became one of the most reproduced scenes in the cycle of the labors, stamped onto Roman gems and worked into mosaic floors from Latium to the provinces. The king in his jar. The hero who had lost two friends on the mountain and gained nothing but the right to walk home and receive his next assignment.
