The Rosetta Stone: A Detective Story Fifteen Centuries Long

In 1799, a trilingual stone discovered in Egypt unlocked a 1,500-year-old writing mystery and sparked the birth of Egyptology.

Picture a hot summer in the year seventeen ninety-nine. Napoleon's French army is strengthening an old fort near the town of Rashid, which Europeans called Rosetta, in the Nile Delta. Soldiers are taking apart ancient masonry when an officer, Pierre-François Bouchard, notices a dark granite slab. It bears three bands of signs, as if three different voices were telling the same story.

It was not a treasure of gold, but something far more precious. The stone carried a royal decree, issued by priests in Memphis in one hundred ninety-six BC in honour of the young king Ptolemy the Fifth. The decree was written three times: at the top in Egyptian hieroglyphs, in the middle in Demotic, the quick everyday Egyptian script, and at the bottom in Greek.

Scholars could read Greek with ease. So what lay before them was a key: one text in a language they understood and two in languages that had been silent for centuries. But a key still has to be turned in the lock.

Why had hieroglyphs become a mystery? Ancient Egypt lived for a long time alongside Greek and Roman culture. Then Christianity arrived, the old temples closed, and the schools of the priests disappeared. The last known hieroglyphic inscriptions date to the end of the fourth century AD, and after that the skill of reading them faded away.

About fifteen hundred years went by, and people saw in hieroglyphs not writing but mysterious pictures. Many scholars believed that a bird stood for the soul, a snake for wisdom, the sun for divine light. They searched for philosophical symbols where there were often just ordinary sounds, names and grammatical endings.

After the French were defeated in Egypt, the Rosetta Stone passed to the British and was taken to London. But copies of the inscriptions had already spread across Europe. A real scientific detective story began: who would be the first to understand what the stone was saying?

The Englishman Thomas Young was a physician, a physicist and a man of rare curiosity. He noticed the oval frames in the hieroglyphic text, the cartouches. Egyptians enclosed royal names in them, and in the Greek part of the decree the name Ptolemy appeared again and again.

Young took an important step. He realised that inside a cartouche the signs could stand not only for ideas but also for sounds, especially when it came to foreign names. He matched some of the signs in the name Ptolemy and made progress in reading Demotic. But a complete system was still a long way off.

Enter Jean-François Champollion. Since childhood he had been fascinated by the East, studying languages, and above all Coptic, the language of Egypt's Christians. Coptic turned out to be a descendant of ancient Egyptian, written in Greek letters with a few extra signs. To Champollion it was like a distant echo of Egypt's living speech.

The key clue did not come from the Rosetta Stone alone. An obelisk from the island of Philae carried a Greek inscription with the name Cleopatra and a hieroglyphic cartouche. Champollion compared the cartouches of Ptolemy and Cleopatra. Sounds that repeated should have repeating signs: p, t, o, l, e.

And suddenly the pieces began to fit. Champollion understood that hieroglyphs were neither just symbols nor a simple alphabet. They were a complex system in which some signs stand for sounds, others for whole words, and still others help to pin down the meaning. Egyptian writing turned out to be a living mechanism, not a collection of sacred pictures.

In September eighteen twenty-two, Champollion presented his famous letter to Bon-Joseph Dacier, secretary of the French Academy of Inscriptions. That was the beginning of Egyptology in the modern sense. According to legend, once Champollion was sure of his discovery, he burst in on his brother and shouted:

— I've got it!

And then, supposedly, he collapsed from the strain. Historians are cautious: the scene may be a family legend. But it captures the main thing. This discovery was not a calm guess but a breakthrough after a race that lasted many years.

The Rosetta Stone did not tell everything by itself. It gave a starting point, like a witness in a detective story who remembers only part of what happened. Young found important traces, Champollion connected them to the language and its writing system, and on the dark slab, beside the Greek lines, the names of ancient kings came into view.
