This podcast dispels the myth that the Classical world, especially Roman and Greek, was homogenous in the upper echelons of society or among the classes of noteworthy individuals.
This podcast does an excellent job of dispelling the myth that the Sahara was ever a natural impermeable barrier to Blacks routinely crossing through continental Africa to/from the Mediterranean Sea and Northern regions of the continent in antiquity.
The argument that ancient/classical Africans can be and/or were magically grouped into Northern or white Africans and Sub Saharan or black Africans betrays ignorance of geography, history, biology and politics.
