Anyway, the backstory I dreamed up for my Coptic knight, to get him out of Egypt and into a fief in Germany was that he was a Coptic sheepherder who went on a pilgrimage to Jerusalem and met a Frankish prince there, and wound up saving his life from thieves. In gratitude, the prince knighted the shepherd, and when he became king, he gave the knight a fief and the title 'Count'. Anyway, I was wondering if:
a. Copts at that time made pilgrimages to Jerusalem?
b. If a typical Latin-rite layman or priest would regard a Copt as a heretic, and vice-versa. (I know about the unpleasantness in 451, but was it still a live, important issue?)
I've done extensive google and wikipedia searches, and found one google books result that seemed to indicate that the answer to my first question is 'yes', but I couldn't find it again, and I found nothing about relations between the Latin Rite Catholics and the Oriental Orthodox after the Moslem conquest of Egypt. I would guess that the answer is 'almost nothing' beyond the bare fact that they're fellow Christians, but I don't want to rely on just a guess. I know this is an obscure question, and if someone could just point me twords some good references, I'd appreciate it.
Edit: So Britain, not Frankonia, and the king meets the Copt in Egypt, not Jerusalem, when he saves the king from Moorish bandits. Britain should be easier to write, anyway, because I can use my undergraduate books (I was a history major), and I have a much wider range of dates in which to set my story, from the first raid on Lindisfarne (793) to the rise of Alfred the Great (878).
