Egyptian was a language spoken in ancient Egypt that was written down in hieroglyphs. With the exception of the Osirans, the Egyptian-speaking humans were the only race to use hieroglyphs. The pharaoh, Erimem, described the Egyptian hieroglyphs as "writing in [her] own tongue".
Sekhmet's bloodlocked tomb, buried beneath the trisilicate mines of Peladon, read in this tongue: "Four females of royal blood shall stand and fall. When the fourth falls, she will usher in the second reign of Sekhmet the Avenger." The rest of the warning was destroyed in the rockfall when Arktos blew up the mines. (AUDIO: The Bride of Peladon)
The Rosetta Stone was written in both Egyptian hieroglyphs and Greek. This allowed the Greek-speaking archaeologists to translate the hieroglyphic script, which they didn't know, into Greek. (PROSE: Love and War, AUDIO: Love and War)
