Section: Book 12: Proportional Stereometry

The Book 12 of Euclid's “Elements” is dedicated to the proportional stereometry, dealing with foundations of cones, pyramids and cylinders. The novel feature of this book is the use of the so-called method of exhaustion (see Prop. 10.1), a precursor to integration which is generally attributed to [Eudoxus of Cnidus][].
