Christoph Scheiner's 1631 Roman treatise on the pantograph, a mechanical drawing instrument, is a geometry textbook for draftsmen and surveyors, printed in Rome by Ludovico Grignani. Its pictures are small geometric diagrams of squares, circles, and construction lines with lettered points, plus a decorative woodcut initial S, and a designer might take from them the clarity of technical line drawing and the use of labelled construction geometry.
