In 1525, Albrecht Dürer published in Nuremberg his Underweysung der messung mit dem zirckel und richtscheyt, instruction in measurement with compass and ruler. It was the first comprehensive textbook of geometry in the German language, written for painters and craftsmen. His Vier Bücher von menschlicher Proportion, four books on human proportion, were printed in October 1528, five months after his death. The third book shows how the proportions of the human figure change according to mathematical rules.
