Mercury Stealing Apollo's Cattle

At a Glance

Central figures: Mercury, infant son of Jupiter and the nymph Maia, god of thieves and messengers; Apollo, god of the sun, prophecy, and music, keeper of a sacred herd of cattle.
Setting: The slopes of Mount Cyllene in Arcadia and the fields near Pieria, as told in the Homeric Hymn to Hermes and adapted into Roman tradition through Ovid and later Latin commentators.
The turn: On the night of his birth, Mercury crawled from his cradle, found Apollo’s cattle grazing unguarded, and drove fifty head away by forcing them to walk backward so their hoofprints led nowhere.
The outcome: Apollo tracked the theft to Maia’s cave, but Mercury offered him a lyre he had fashioned from a tortoise shell, and Apollo accepted the instrument in exchange for the cattle and a share of divine honors.
The legacy: Mercury’s theft established him as the god of commerce, trickery, and negotiation among the Roman pantheon - the patron of merchants and thieves alike, honored at the Porta Capena and in the temple on the Aventine dedicated on the Ides of May.

The child was not yet a day old. Maia, daughter of the Titan Atlas, had borne him in a cave on Mount Cyllene before dawn, and by the time the sun climbed high enough to warm the rocks at the cave’s mouth, the infant had already grown restless. His mother slept. The swaddling cloths lay in a heap. Mercury stood on his new legs, walked to the entrance, and looked out at a world he intended to rearrange.

A tortoise crossed his path. He killed it, scooped out the shell, stretched ox-hide across the opening, fitted two horns of reed, strung seven cords of sheep-gut between them, and plucked. The sound that came out of the thing stopped him. He set it down carefully. He had other business first.

Fifty Head, Walking Backward

The cattle of Apollo grazed in the meadows near Pieria, fat and white, sacred animals that the sun-god counted each evening the way a miser counts coins. Mercury found them at dusk. Fifty cows, separated from the rest, standing stupid and calm in the last of the light.

He did not drive them forward. He tied bundles of tamarisk and myrtle to their hooves, bark-side down, so the tracks would be muddled, and then he forced the animals to walk backward - tails first, heads last - so that any tracker following the prints would be led toward Pieria rather than away from it. Mercury himself walked on woven sandals of wicker and leaves that left no mark at all. He was half a day old and already thinking like a thief.

He drove the herd south through the night, past Onchestus, past the vineyards of Boeotia, into a hollow near the river Alpheus. There he penned them in a stone enclosure hidden by willows. Two of the cows he slaughtered. He cut the meat into twelve portions - one for each of the great gods of the council, himself included, since he saw no reason to be modest - and roasted the flesh over a fire he kindled by spinning a laurel stick in a block of dry wood. The fat he burned. The hides he stretched over rocks. Then he scattered the ashes, buried the coals, and walked home to Cyllene in the grey hour before morning.

He climbed back into his cradle. He pulled the swaddling cloths around himself. He closed his eyes.

Apollo Counts His Herd

Apollo noticed at once. Fifty head missing, and the tracks around the pasture made no sense - hoofprints that walked toward the herd rather than away, as though the cattle had arrived from nowhere and then vanished. He followed the marks in circles for half a morning before giving up on the trail and turning to divination.

An old man near Onchestus had seen something. A child, he said. A very small child driving cattle backward down the road, holding a switch, wearing sandals made of leaves. Apollo did not need to hear more. Word had already reached him that Maia had borne Jupiter a son the day before.

He went to Cyllene. He found the cave. He found the cradle. Inside it lay Mercury, wrapped tight, eyes shut, the picture of an infant sleeping off a difficult birth.

Where are my cattle?

Mercury opened one eye. He stretched. He yawned with elaborate innocence.

I was born yesterday, he said. My feet are soft. The ground is hard. Do I look like a cattle driver to you?

The Lyre in the Cave

Apollo was not charmed. He seized the child and carried him to Jupiter’s seat on Olympus, demanding judgment. Mercury kept up the performance - wide eyes, trembling lip, a newborn’s helpless whimper - but Jupiter had known the boy’s nature before birth. He looked at his youngest son and told him, flatly, to return the cattle.

Mercury led Apollo back to the hollow near the Alpheus. The cows were there, penned and calm, minus the two he had slaughtered. Apollo counted them. He was still furious about the missing pair when Mercury reached into the folds of his swaddling and produced the tortoise-shell lyre.

He sat on a rock and played.

The sound stopped Apollo the way it had stopped Mercury himself. The strings held something the sun-god had never heard - not prophecy, not the harsh clang of his own silver bow, but melody shaped by human intervals, a voice for grief and joy that could be carried in two hands. Apollo, who understood music the way a river understands downhill, recognized at once that this instrument mattered more than fifty cattle or a hundred.

Give it to me, he said.

Mercury held it out. The bargain took less time than the theft. Apollo received the lyre. Mercury received the cattle - all of them, the remaining forty-eight and the right to keep the two he had eaten. More than that: Apollo gave him a golden staff, the caduceus, a rod of authority over herds and flocks, and acknowledged him as a fellow god of Olympus, entitled to move between the halls of Jupiter and the roads of the mortal world.

The Rod and the Road

Jupiter confirmed it. Mercury became the messenger, the boundary-crosser, the god who moved between high and low, sacred and profane, living and dead. His province was the road itself - every transaction made on it, every oath sworn at a crossroads, every merchant’s deal and every pickpocket’s sleight of hand. The Romans built his temple on the Aventine and dedicated it on the Ides of May, the month that bore his mother’s name. Merchants gathered at the Porta Capena to sprinkle their goods and their coin-purses with water from the spring of Mercury, asking the god’s favor for the trading season.

Apollo, for his part, never lost another cow. He had the lyre, and from it he drew music that moved stone and stopped rivers. In later years, poets said the lyre was worth more than any herd - but Apollo had not accepted it because of its worth. He had accepted it because when Mercury played, the sound told the truth about something that language could not reach, and Apollo, god of every form of clarity, could not resist a new kind.

Mercury, meanwhile, kept the sandals. He improved them. Eventually they grew wings.
