The worst thing I have ever read.
While I bought it as a literary book, it talks about the emperors of Byzantium. It starts with Julian the Apostate, whom it praises, and in the end it concludes that he should not have been called an apostate.
At the same time, it mocks Constantine the Great and does not consider him worthy of being called "Great," and it also mocks Christ, whom the author claims is neither God nor man.
