I've been trying to find an answer to this and have yet to come across anything extensive. Imagine you break down the past 2500 years by century. Now for each century, what were the most widely read and/or distributed works? You could further break this down by geography, but I think just answering the initial question is a good enough start.
Why is this important? I think we tend to filter the works of the past to fit into our modern mindset. I think that if you happened to control all our ((textbooks, universities, and media)), you could find obscure or even just lesser known works of the past to use to create whatever history you want. Knowing what was actually read is a way out of that. Theres probably also a lot of great stuff that has been lost to time because the modern academy doesn't have a place for it.
