A set of four ancient Egyptian limestone canopic jars, used for holding organs removed from the deceased during the mummification process. Each of the jars represents one of the four sons of Horus: (L-R) jackal-headed Duamutef (stomach); baboon-headed Hapi (lungs); falcon-headed Qebehsenuef (intestines); and human-headed Imsety (liver). Artist unknown; ca. 900-800 BCE (Third Intermediate Period). Found at Abydos; now in the Walters Art Museum, Baltimore. Photo credit: Walters Art Museum.
My story is set in a world inspired by 300 BC, more specifically the hellenistic empire. It's set in a city loosely inspired (as in geography and the library) by Alexandria, where people mainly speak Arabic mixed with Greek (there are far more resources on Arabic than Egyptian, which is why I chose Arabic, and I didn't want to invent a language). Now I'm wondering if using Arabic outside its historical context, in "Egypt" and without Islam would be wrong?
