Des Circkels vnnd Richtscheyts, auch der Perspectiua, vnd Porportion der Menschen vnd Rosse, kurtze, doch gründtliche vnderweisung, deß rechten gebrauchs
Heinrich Lautensack's 1564 German manual on compass, straightedge, perspective and the proportions of humans and horses, printed for craftsmen and artists learning geometric construction. The pages show woodcut diagrams of nested squares, cubes, stepped blocks and a tall polyhedral figure, drawn as labelled geometric constructions with numbered figures and explanatory German text above and below. A designer could take from them the clarity of line-based perspective construction and the way single-colour woodcut diagrams explain three-dimensional form.
