Which ancient object helped scholars decipher Egyptian hieroglyphs?

The Rosetta Stone helped scholars decipher Egyptian hieroglyphs.

The stone is a granodiorite decree issued in 196 BC during the reign of Ptolemy V. Its text appears in three scripts: Egyptian hieroglyphs, Demotic Egyptian, and Ancient Greek. Because scholars could read Ancient Greek, the repeated content provided a crucial comparison for understanding the two Egyptian writing systems.

French soldiers discovered the stone near the town of Rashid, known in European languages as Rosetta, in 1799 during Napoleon’s campaign in Egypt. The British captured it after France’s defeat, and it was transferred to the British Museum in London in 1802, where it remains on display.

Jean-François Champollion published a major breakthrough in decipherment in 1822. He recognized that hieroglyphs could represent sounds as well as ideas and used royal names, including Ptolemy, to connect signs with the Egyptian language. The stone was not the only evidence, but it became the best-known key to the decipherment.
