Classical peoples seem to have considered Berbers to be civilized or at least worthy of civilization. St. Augustine is probably one of the most famous Berbers that is commonly seen as a "European" person (
https://en.wikipedia.org/wiki/Augustine_of_Hippo), despite being from Africa and originating from an African ethnic group. He probably neither looked like some random Irish guy nor looked like a Viking, but he was seemingly accepted into a European Christian milieu. This likely leads to one of two conclusions:
1) Berbers, or at least St. Augustine, were considered white or Caucasoid by other European peoples, especially Romans and Greeks.
2) Classical European peoples, especially Greeks and Romans, did not recognize, or at least did not emphasize as important, the concept of whiteness or being Caucasoid.
Perhaps both? They couldn't have been unaware of the differences in "phenotype" among the many different peoples they encountered, but to my knowledge while, for example, the Romans of the Republic hated the Carthaginians like poison, I don't recall that relative "shades" of pigmentation came into the matter. In terms of the "Syrians", which they often used as a blanket term for the Near East, and the "Egyptians", the early Romans of the Republic feared their influence in terms of their religions, their love of luxury, the "god" like status they gave their rulers, all things you might say they eventually adopted, but I don't remember reading of them fearing them because they "looked" different. Nor were slaves treated differently based on "race" to my knowledge. Bad or good it was all the same, although "educated", "literate" slaves, so slaves from Greece or the Near East were more valued in many cases. An educated, coastal North African would undoubtedly have been considered "civilized", I would think, if not some pastoral nomad of the more interior areas.
In terms of the Berbers we don't even know what they looked like at the time that they came into contact with Rome. We would need a string of ancient dna results to know whether at that time more of them looked like the first picture, which is now a minority, or the second, which is also a minority, or somewhere in between, or how much variation there was, for that matter, within and between areas.
As for Augustine, I was condemned to study "The Confessions" in high school, even translated some of him from the original, and I don't think his "race" ever came up, but then neither did the "race" of the Egyptian hermits and monks, or of Jews like Jesus, and Mary, and Peter, and Paul, and on and on. Anyway, despite the fact that I resented translating him as much as I did translating Caesar, I quite liked Augustine...there he was, intellectually and spiritually drawn to his mother's religion, but quite unable for a long time to drag himself away from the fleshpots and all his vices. Well, all Monica's praying worked in the end, which is why she was held up to us as the model of Catholic motherhood, but I do like his very human prayer, "Lord, grant me chastity; but not yet."
That wasn't the part emphasized by my teachers of course. We were to have the utmost respect for him. We were also taught to mourn the fall of his "city", "The City of Man", Hippo, in his dichotomy, to the barbarians as he lay dying. Our teacher made it very affecting, indeed. The North Africans were part of the "civilized" world; it was the Vandals who were the barbarians. Maybe that's part of why I find so many things posted on these kinds of Boards so bizarre.
@Twilight,
Absent ancient dna, which we've gotten only recently, how can the assignment of y dna lineages be anything but speculative? Granted, some speculations are more supported by modern dna studies, archaeology, linguistics, etc., than others, but major mistakes can be made. After all, many people thought until just recently that down stream R1b clades originated in, and spread from, the Atlantic seaboard.
