Ioannis Taisnier Hannonij De vsu annuli sphaerici libri tres : in quibus quicquid ad geometriae perfectionem requiritur continetur
A 1550 Latin treatise on geometry, surveying and the sphere by Jean Taisnier of Hainaut, printed in Palermo for a scholarly audience of mathematicians and surveyors. Its woodcut diagrams show surveyors measuring towers, fortifications and gardens with instruments and sight lines, and a designer could borrow their clean line geometry, labelled construction diagrams and bold black-and-white hatching.
