Cosimo Bartoli (1503-1572), the Florentine humanist who translated Alberti's writings on architecture into Italian, turned in this book to the measurement of the world around him. Written in Italian for practitioners rather than scholars, it brings together what Bartoli had learned from the mathematicians he had studied and translated, among them Gemma Frisius, Apian, Dürer, Alberti, Oronce Finé, Stöffler and Peurbach, and applies it to the everyday problems of the surveyor, the engineer and the mapmaker.
The first book deals with measuring heights, depths and distances; the second and third with plane geometry; the fourth with surveying and mapping, including the construction and use of the compass; the fifth gives Euclidean demonstrations of the measurements in the first book; and the sixth treats square roots. Bartoli also discusses perspective and geometrical projection. The woodcuts show the instruments and methods of sixteenth-century surveying in practice, and the volume opens with an architectural title and a full-page woodcut portrait of the author, which Cicognara noted as a feature of this first edition.
One of the best sixteenth-century treatises on practical geometry and surveying, and an important source for the instruments and methods used to measure land and draw maps in Renaissance Italy.
