The Rosetta Stone, discovered in 1799, was pivotal in deciphering Egyptian hieroglyphs because it featured the same text written in three scripts: Greek, Demotic, and hieroglyphs. Since scholars could read Greek, they could use it as a key to unlock the meaning of the hieroglyphs. Champollion, a French scholar, made significant breakthroughs in understanding the script by comparing the languages. This breakthrough allowed historians and archaeologists to access vast amounts of ancient Egyptian literature, religious texts, and administrative documents, fundamentally transforming the field of Egyptology and deepening our understanding of ancient Egyptian civilization.
