The classic icon of st. Athanasius the Great, from here
«...Most likely, St Athanasius the Great was not only black but may have had pygmy stock mixed with his egyptian background.
In the book "The Holy Fire" by Robert Payne (pg67&68) the author relates a quote from the Emperor Julian the apostate, who spoke of Athanasius as: "Hardly a man, only a little manikin". His opponents many times called him "the dwarf".
It goes on to say that more than one commentator refer to the unusual darkness of his skin. The author writes, "He had a hooked nose, a small mouth, a short reddish beard which turned up at the ends in the egyptian fashion, and his skin was blackish.
To all this, Gregory Nazianzen described St Athanasius as "Angelic in appearance and still more angelic in mind"...»
