The artifact discovered that provided insight into the Rosetta Stone is the Rosetta Stone itself, found in 1799 during Napoleon's campaign in Egypt. This granodiorite stele features inscriptions in three scripts: Greek, Demotic, and hieroglyphics, which allowed scholars to finally decipher Egyptian hieroglyphs. The Greek inscription provided a key to understanding the other languages, facilitating the study of ancient Egyptian history, religion, and culture. The Rosetta Stone’s discovery was a groundbreaking moment in the field of Egyptology, leading to a resurgence of interest in ancient Egypt and unlocking centuries of knowledge previously lost due to the inability to read hieroglyphics.
