Beschrijving van het nut van de grafometer, pagina 5 van 10 1777 - 1778

This page is from a 10-page illustrated book on the use of a “grafometer” (possibly a type of drawing instrument) created by Dutch artist Antoine George Eckhardt in 1777. Eckhardt, born in 1740 and known for his detailed drawings and scientific illustrations, produced this page as a guide for those interested in learning about the grafometer. Eckhardt, who died in 1810, likely intended this page to be a practical tool for aspiring artists and draftsmen, explaining the mechanics of the instrument and its role in various drawing processes. This page, measuring 510 mm in height and 330 mm in width, is likely part of a larger work dedicated to the technical aspects of drawing.
