Guilelmi Oughtred ... Opuscula mathematica hactenus inedita
Opuscula mathematica is a 1677 Latin collection of mathematical treatises by William Oughtred (1575-1660), printed at the Sheldonian Theatre in Oxford for scholars of mathematics. Its pictures are plain line diagrams of pulleys with lettered points, weights and rope runs, and triangles with labelled vertices, drawn with a clean, schematic economy that a designer might borrow for technical or instructional graphics.
