De rerum varietate, libri XVII
De rerum varietate is a 1558 Latin natural philosophy treatise by the Milanese polymath Girolamo Cardano, printed at Avignon by M. Vincentius for scholars and students of natural science. Its pictures are plain line diagrams of circles, ellipses and lettered geometric figures, with hatched shading in one case, offering a designer a sparse, precise vocabulary of schematic technical drawing.
