The thirteen or fourteen years of DUrer's life between his return from Venice and his journey to the Netherlands (spring 1507 - midsummer 1520) can best be divided according to the classes of work with which, during successive divisions of the period, he was principally occupied.
The copy, together with the many careful and highly finished preparatory studies for the heads, limbs and draperies which have been preserved, shows that this must have been the one of DUrer's pictures in which he best combined the broader vision and simpler habits of design which had impressed him in the works of Italian art with his own inherited and ingrained love of unflinchingly grasped fact and rugged, accentuated character.
In 1511 these two works were brought out for the first time, and the Apocalypse series in a second edition; and for the next three years, 1511-1514, engraving both on wood and copper, but especially the latter, took the first place among DUrer's activities.
The imaginative force of the presentation, coming from a man of DUrer's powers, is intense; but what consciously occupied him most may well have been the problem how to draw accurately the proportions and action of a horse in motion.
The principal editions of Durer's theoretical writings are these :- Geometry and Perspective.
