The Key to a Dead Language Was a Tax Cut Carved in Stone

On July 15, 1799, a French demolition party pried a slab out of an old Nile Delta wall. Its text was gloriously dull, a royal tax cut and a new state religion. It would unlock a civilization silent for fourteen centuries, and the country that carved it has never laid eyes on it.

Napoleon had landed in Egypt a year earlier, sailing 400 ships and 54,000 men onto the beaches outside Alexandria and bringing along some 160 scholars to catalogue everything they found. By the summer of 1799 his army was rebuilding Fort Julien, an old Mamluk stronghold a few miles inland from the port town of Rashid, which the French called Rosetta. A party of soldiers was tearing down a dilapidated wall when they noticed a slab of granodiorite built into the masonry, its face covered in three kinds of writing.

The officer in charge, a young engineer named Pierre-François Bouchard, recognized at once that this was no ordinary stone. The top band was Egyptian hieroglyphs, the middle a cursive Egyptian script called demotic, and the bottom ancient Greek, a language scholars could still read. Skim the Greek and it said the three texts said the same thing. Here, for the first time, was a parallel translation of a script no one had read in fourteen centuries.

Bouchard had the stone sent to the scholars in Cairo, and the find was printed in the army newspaper there. Then the war took it. When the French surrendered to the British at Alexandria in 1801, the British commander declared every French antiquity a spoil of war. A French general tried to claim the stone as his private property and lost. A British colonel escorted it home, and it has stood in the British Museum since 1802, its sides still painted with the words "Captured in Egypt by the British Army in 1801" and "Presented by King George III."

For more than two decades the best minds in Europe threw themselves at the hieroglyphs and failed. The English polymath Thomas Young proved that the oval-framed clusters of signs, the cartouches, spelled out foreign names like Ptolemy, and that some signs could stand for sounds. But he refused to believe hieroglyphs could be phonetic for anything but foreign names, and he stalled there.

The breakthrough belonged to a Frenchman who never touched the stone. Jean-François Champollion had been obsessed with Egypt since childhood and, crucially, knew Coptic, the liturgical language of Egyptian Christians and the last living descendant of ancient Egyptian. On September 14, 1822, staring at a cartouche copied from Abu Simbel that spelled the pharaoh Ramesses, an Egyptian name rather than a Greek one, he saw that the signs were phonetic after all and that the language underneath them was Egyptian. He ran to his brother's office, thrust his notes at him, gasped "Je tiens mon affaire!" ("I've got it!"), and fainted. Two weeks later he read his findings to the Académie in Paris. The talk became the Lettre à M. Dacier, the founding document of Egyptology. Champollion died at forty-one, ten years later, his grammar and dictionary published only after his death by his brother.

Here is the joke. The stone is a decree from 196 BC, issued by a council of priests at Memphis to flatter the thirteen-year-old Ptolemy V Epiphanes. "Of the revenues and taxes levied in Egypt some he has wholly remitted and others he has lightened," it announces, "in order that the people and all the others might be in prosperity during his reign." It cuts taxes, frees prisoners, and orders a statue of the boy-king set up in every temple in Egypt and worshipped three times a day. It is, in essence, a government press release. And it became the most visited object in the British Museum and the most famous inscription in archaeology.

The echo is still being fought over. Egypt's antiquities chief said late last year that the stone was "illegally taken" in wartime and that Egyptians "have never seen it." The British Museum answers that the 1801 treaty, signed by an Ottoman admiral, makes it lawful, and that British law bars it from sending the stone home. A slab carved to project a boy-king's power now projects someone else's, and the country that made it still cannot read the original in its own land.
