I was, frankly, quite shocked to learn only a few weeks ago that St. Augustine was a Manichean for many years before converting.
BTW, I was also shocked to learn that Augustine died when his home of Hippo located on the Southern Mediterranean coast was overrun by a bunch of Germanic Vandals!

Speaking of the Vandals, it may not be surprising that blonde hair and blue eyes is as common as it is among the Berbers.
