Een tekenaar tekent een portret

An artist stands at a desk equipped with a vertical sighting rod, meticulously transferring the sitter's features onto a frame. To the left, a man sits for his portrait, while a bed with heavy curtains and a candle stand occupy the background. The image serves as a technical demonstration of how to achieve correct perspective through mechanical aids.

Published in Dürer’s Underweysung der Messung (Manual of Measurement), this work represents the Renaissance drive to ground art in the mathematical certainty of geometry and natural philosophy. It illustrates the transition from medieval workshop traditions to a more scientific approach to optics and the representation of three-dimensional space.
