The Rosetta Stone, discovered in 1822, was key to deciphering Egyptian hieroglyphs. This artifact features a decree inscribed in three scripts: Greek, Demotic, and hieroglyphic. Since scholars could read Greek, the stone enabled them to make significant progress in understanding the previously enigmatic hieroglyphs. The successful translation of the Rosetta Stone by Jean-François Champollion in 1822 opened the door to the study of ancient Egyptian language and culture, leading to a greater understanding of Egypt's rich history and contributions to human civilization.
