Britannica: hieroglyphicsAncient Egyptians had three different writing systems. The oldest, best known, and most difficult to read is called hieroglyphics. The word, which means “sacred carving,” was used by Greeks who saw the script on temple walls and public monuments. The Greeks were somewhat mistaken in their terminology because hieroglyphs were used on gravestones, statues, coffins, vessels, implements, and for all sorts of nonreligious texts—songs, legal documents, and historical inscriptions.
