A Venetian geometer whose book, La Practica della Perspectiva (1568-69), presents the techniques of perspective, illustrated in part with a range of polyhedra. Partly based on the methods and writings of the great artist Piero della Francesca (1416-1492), but written in a more readable and humanistic style, it includes the earliest drawing of the truncated icosidodecahedron and one of the earliest representations, along with that of German goldsmith Wenzel Jamnitzer (1508-1585), of a rhombicosidodecahedron. La Practica was one of the most respected texts on perspective in the sixteenth century, comparable to Albrecht Dürer's Painter's Manual.
