Fiadidja-Mahas- Spoken currently in modern day Sudan. There are 2 different varieties of this specific Nubian language; Fadidja and Mahas.
Kenuzi-Dongola- Spoken by people of Sudan AND Egypt.
Old Nubia had ways (similar to hieroglyphics) to keep archives, but not all were accurate. During the Christian Nubian era the Nubian alphabet resembled the Greek and Coptic ones. The main way to speak Nubian is in way of tones, similar to intonations and chanting.
Nubian women were highly thought of and respected. They were depicted as being leaders, scholars and goddesses. Unlike most societies of the time, Nubia treated women as equals.
An Interesting fact which makes the study of Nubia much more interesting for the theatre oriented is the Broadway show Aida. It is about a “forbidden love” between the next in line to be the Egyptian pharaoh and the Nubian Princess.
