If I hadn't been reading this for a challenge, I would have given up in the middle. It improved towards the end, but on the whole I found it heavy going. The author gives little sense of the setting in Alexandria, although she does manage to get over the way in which the vibrant intellectual life of the city was being gradually squeezed by Christianity. She shows how the new religion was largely taken over by people with no interest or understanding of the doctrines, but determined not to permit any viewpoint but their own.
What I found particularly irritating was the pseudo-archaic language and the self-consciously "beautiful" prose. Other reviewers apparently enjoyed this, but as far as I was concerned, it made the book painful to read.
