E.E. Evans-Pritchards "Witchcraft, Oracles and Magfic among the Azande, 1937, is a great read. (get the abridge version, the unabridged is very very very tedious)It was one of the first modern ethnographies in anthropology. I havent read more than excerpts of his writing from egypt though, but they seem to be quite inciteful as well.
Thank you, I'll look into it.
