"For each of Euclid's thirteen Books, the author has given a general description of the contents and structure of the Book, plus one or two sample proofs. In an accompanying section, the reader will find items of general interest for mathematics, such as the question of parallels, squaring the circle, problem and theory, what rigor is, the history of the platonic polyhedra, irrationals, the process of generalization, and more." "This is a book for all lovers of mathematics with a solid background in high school geometry, from teachers and students to university professors. It is an attempt to understand the nature of mathematics from its most important early source."--BOOK JACKET.
