pantograph

pantograph
   A device for copying a two-dimensional figure to a desired scale, consisting of styluses for tracing and copying mounted on four jointed arms in the form of a parallelogram with extended sides. Leonardo da Vinci (Italian, 1452-1519) used one. Pantographs are based on the simple principle of the parallelogram in Euclidean geometry understood 2300 years ago. The artist moves a pointer attached to one part of the pantograph along the outline of the original image, and a pencil attached to another part copies the image at either the same size, larger or smaller. The placement of the pointer and pencil determines the overall scale.The one Thomas Jefferson (American, 1743-1826) devised and used to copy letters as he wrote them can be seen at his Monticello home. Such tools have been made largely obsolete by photographic and other technologies, but are great for studying scale.
