SECOND EDITION, ENLARGED, of Cavalieri's principal work, 'THE FIRST TEXTBOOK OF WHAT ARE NOW KNOWN AS INTEGRATION METHODS. The work includes the statement of "Cavalieri's principle" for the determination of areas and volumes, which considers an area as made up of an indefinite number of equidistant parallel line segments, and a solid as made up of an indefinite number of parallel plane areas. 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). Cinti 250 (127); Honeyman II 650; Norman I 148 (419); Riccardi I 325.
