I have a number of books on Roman historiography (particularly Livy) that I could recommend if anyone is interested. For starters I've been reading Livy on the Hannibalic War by D. Levene and it has been really enlightening and has changed the way that I have read and thought about Livy to a large extent. There are points throughout where I think he is overreaching but his 40 or so pages where he discusses racial characteristics in Livy was particularly worthwhile. Immensely well researched.

The most illuminating book I have read in a long time though that might appeal to a broader audience is The Roman Triumph [It appears to be on sale for an immensely low price] by Mary Beard. Beard is known for writing books that question almost everything that is taken for granted in whatever field she is studying at the time. In this case she challenges some fundamental aspects of the Roman triumph and makes us reconsider just about every image we have of it. I disagree with some of her conclusions, and she does over-reach at times, but the sceptical methodology she brings to the field is astounding.

I've got lots of other stuff if people are interested. Like I said it is mostly on Roman historiography (particularly Livy) and is all scholarly material.
