Look for original sources-- that way, you'll be getting samples of how people used to think rather than interpretations from more modern people.
You might want to try Ex Urbe-- Ada Palmer is good about how much the way people think has changed.
Look for original sources
I've actually done this on several occasions. But I mostly just get the feeling that "something is wrong here" and I can't quite put together how anybody could actually think what the source is saying makes sense.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
