Between 1603 and 1605 Christoph Scheiner invented the pantograph which is an instrument for copying plans on any scale. The use of mechanical linkages transfer what is drawn with one pen through fixed rods to a second pen which is drawing at a different scale. Christoph Scheiner published his invention in Pantographice seu Ars delineandi res quaslibet per parallelogrammum lineare seu cavum which was published in Rome in 1631. The device has utility in copying diagrams and there are still tools and tools that use the same principle.
