Page "Albrecht Dürer" Paragraph 37

On his return to Nuremberg, Dürer worked on a number of grand projects with religious themes, including a crucifixion scene and a Sacra Conversazione, though neither was completed.

This may have been due in part to his declining health, but perhaps also because of the time he gave to the preparation of his theoretical works on geometry and perspective, the proportions of men and horses, and fortification.
