Do you genius's know when these statues where made? I'm guessing post Renaissance. You ever heard of the Dark Ages prior to the Renaissance? It was Dark for a reason. This where Europes Black Kings, Knights and Priests come. The Black Moors. Before that also. White people were certainly around but things were for the most part Black ran. And Africa was the center of civilization. Black Egyptians as everyone knows now also.
Black ran? Well except for Northen Europe, Slavs, Russians, Mongols, Chinese, Japanese, Native American/Eskomo, Indonesians...2/3 of all mankind. Yes the Moors concoured southern England, Wales, south France, Sicily and tip of Italy. About 400 years while they set up Islam....then came the Crusades and pushed them back to No Africa. They did leave a lot of seed behind. My Grandaddy was Black Welsh with kinky hair. Most Sicilians today are Italian, French, Moorish mix. Great genes and make great Bodybuilders, beautiful ladies and "Bosses."
All mankind came out of Africa. Does not mean Negroid. Negro, white, and Asian all have about the same DNA connection to Africa.
Now about Alexandria and Christians. My suspisions are that there is more than revealed hidden in the caves below the Vatican. On one of my several visits to Vatican City I had an archivial scholar from the Vatican as my guide. It was interesting to learn that Jesus had brothers and sisters, his mother was VIRTUOUS, not virgin, and he was likely married. Much is hidden from the faithfull. Has to be or then the Emperor Wears No Clothes.
