Prostitution in the Byzantine Holy Land (2010)

The parts about Theodora are suspect, as there's only one source for them: the Secret History, which was clearly written by a disgruntled former palace insider. Furthermore, the style of writing and the accusations made are typical of smear campaigns of the time.

Given what we know of high-end prostitution of the time, a good chunk of the things described in that account don't make a lot of sense.
