The trial of the “three godless painters”

Three of Dürer's pupils — the brothers Hans Sebald and Barthel Beham and Georg Pencz — were charged with godlessness and banished from Nuremberg, and one of his best block-cutters, Hieronymus Andreae, was jailed for links with the rebel peasants. How Dürer himself took it is unknown.

At work on his treatise on proportion to the end

In his last years, his health failing, Dürer devoted himself to his treatises on geometry, the proportions of men and horses, and fortification. He died in Nuremberg aged 56, leaving a considerable estate of 6,874 florins; the Four Books on Human Proportion appeared shortly after his death.
