He is well known as a portrait painter, his works include historical pictures and portraits; among the latter may be named those of Maximilian I. and Charles V. His bust of Margrave Philip in the Munich Gallery tells us that he was connected with the reigning family of Baden as early as 1514. At a later period he had sittings with Margrave Christopher of Baden, Ottilia his wife, and all their children, and the picture containing these portraits is still in the gallery at Karlsruhe. Like Dürer and Cranach, Baldung supported the Protestant Reformation. He was present at the diet of Augsburg in 1518, and one of his woodcuts represents Luther in quasi-saintly guise, under the protection of (or being inspired by) the Holy Spirit, which hovers over him in the shape of a dove.
