Nazi theory explicitly rejected "materialism", and therefore, despite the realistic treatment of images, "realism" was a seldom used term. A painter was to create an ideal picture, for eternity. The images of men, and still more of women, were heavily stereotyped, with physical perfection required for the nude paintings. This may have been the cause of there being very few anti-Semitic paintings; while such works as "Um Haus and Hof", depicting a Jewish speculator dispossessing an elderly peasant couple exist, they are few, perhaps because the art was supposed to be on a higher plane. Explicitly political paintings were more common but still very rare. Heroic imagery, on the other hand, was common enough to be commented on by a critic: "The heroic element stands out. The worker, the farmer, the soldier are the themes ... Heroic subjects dominate over sentimental ones".
