I have not seen that program, but am interested in viewing it. I was required to write a research paper on ancient writers for one of my humanities courses at college. Your topic brings up a little of my memory on what I wrote. This research project I worked on was in the 90's, and my memory is failing me. Perhaps you or someone on this thread could help me recall a particular word I'm struggling to remember.
When someone copies a text and changes or adds to it to support a particular belief (Christianity), there is a specific word for this action. I can't recall it and now it is like a little gnat in my head. The word was used often when discussing the copying and translation of Josephus' works.
