Christophori Scheiner, e Societate Iesu Germano-Sueui, Pantographice, seu, Ars delineandi res quaslibet per parallelogrammum lineare seu cauum, mechanicum, mobile : libellis duobus explicata & demonstrationibus geometricis illustrata, quorum prior epipedographicen, siue planorum, posterior stereographicen, seu solidorum aspectabilium viuam imitationem atque proiectionem edocet
Christoph Scheiner's 1631 Roman treatise on the pantograph, a Jesuit mathematician's manual of geometrical drawing instructions for copying plane and solid figures. Its pages are numbered geometric diagrams with lettered points, rectangles, triangles, circles and construction lines, drawn in clean black ink on paper. A designer could take from them the plain logic of proportional scaling and grid-based construction, with lettered vertices and dashed guide lines.
