The ancient artifact discovered in Egypt that helped decipher hieroglyphics is the Rosetta Stone. Found in 1799 near the town of Rosetta (Rashid), it features a decree inscribed in three scripts: Greek, Demotic, and hieroglyphics. Scholars utilized the Greek text, which they could read, to understand the ancient Egyptian hieroglyphic script. The Rosetta Stone was crucial in unlocking the language of ancient Egypt, enabling historians and archaeologists to better understand its rich history, literature, and culture. It remains an iconic symbol of linguistic discovery.
