Theodora by Antony Bridge (nonfiction 1978)

Bridge purports to give Theodora the nuanced analysis she deserves, and he repeatedly castigates Procopius for his hatred of her, trying to give the real story.  And although he does that, and the story is amazing, Bridge wholeheartedly jumps on the woman-hating, salacious stories-and-all bandwagon when it comes to Antonina, the wife of Belisarius.
