The central idea behind Scheiner’s pantograph is the use of a parallelogram of levers for the proportional
enlargement and diminution of a flat image. As such, it provided the basis for the pantograph today.
Mounted vertically it could also serve as a perspective machine... The pantograph is less mechanically elegant
than Cigoli’s perspectograph, bus possesses the operational advantage that the relative size of the image
as transcribed by the draftsman’s hand can be adjusted at will without altering the distance between the
viewer’s eye and the intersection
