Here’s something that I had never heard of! It’s a website, based at Google Sites, called the Latin Josephus Project. The URL is https://sites.google.com/site/latinjosephus/.
It contains the full text of the Latin Josephus for both the Jewish War and Antiquities, given in parallel with the Greek, and Whiston’s translation. These words were translated in the 6th century, probably by Cassiodorus. They are found everywhere in medieval monastic libraries.
This is a very useful piece of work!
