Lively guide by a prominent historian focuses on the role of Euclid's "Elements" in subsequent mathematical developments. Elementary algebra and plane geometry are sole prerequisites. 80 drawings. 1963 edition.
I'm going to count this as read, because I did read the whole thing, although there were large chunks that I didn't understand. I'll try again someday, and hopefully get more of it.
I wish I had read this book the first time that I saw it, when I was 12 years old. It is a wonderful survey of a lot of the fields of modern mathematics. It’s fairly accessible.
