Egyptians developed hieroglyphic writing around 3400 BC, and it was used until around 396 AD. Hieroglyphics could represent sounds or symbols and included images like the Eye of Horus. The Rosetta Stone, discovered in 1799, helped scholars decipher hieroglyphics because it included three translations of the same text in hieroglyphic, demotic, and Greek. Scribes were the only people trained to read and write hieroglyphics, keeping government records and writing letters.
