Second edition, originally published in Bologna in 1635, of Cavalieri's treatise on indivisibiles, or infinitesimals, "constitutes the first textbook of what are now known as integration methods... Cavalieri's principle provided a simple and speedy alternative to the method of exhaustion, enabling easy calculation of such problems as the area of an ellipse and the volume of a sphere" (Norman, p.149).
