Songhay is from the 15th century and was developed after contact with other civilizations. Tamasheq is not sub-Saharan as it was developed in North Africa. I commented about Ge’ez and how it’s fairly modern (1k years old). So I agree that it’s sub-Saharan, but just not that old and unlikely to be used in the area that is presently Zimbabwe. There may be other written languages in sub-Saharan Africa that we don’t know about that were used in ancient times where we would be impressed with these engineering structures.
