Justinian's Flea: The First Great Plague and the End of the Roman Empire - William Rosen An excellent read, but if you're expecting a straight narrative regarding the earliest known plague epidemic, look elsewhere. Rosen weaves in history from many different aspects: architecture, mathematics, burgeoning medical science, biographic summaries of many of Justinian's contemporaries, art, philosophy, religion, wars, etc. This is more of a wide-ranging look at the gradual move from antiquity to the medieval period, with the plague casting a shadow over the entirety. Meanders a bit, especially near the end where I feel Rosen got bogged down in his own narrative, but definitely an interesting read as long as one isn't expecting plague and nothing but the plague.
