Kriston and Cindi, I'm glad those look good to you! I think they're really nice books. (My boys are mad about history, so I use it as a "gateway" to other--slightly less popular!--subjects quite often.) Along those same lines, we have also liked the Jeanne Bendick history of science books about Archimedes and Galen--there's also one about Galileo that I haven't been able to turn up yet. Another one we like a lot is Julia Diggins's "String, Straight-Edge, & Shadow," a nice history of geometry.
