QUOTE : Whereas painters of the early and middle 1400s enriched their own (and their countrymen's) understanding of the Gospel by recreating it in reality, their successors used this technique to study (and broaden) their entire world view. Hieronymus Bosch mastered a whole genre by merging the realism of Flemish painting with fantastic allegories of the human condition. His pictures of vermin and birds in men's clothing, atrocities, and weirdly juxtaposed objects use the realism of the earlier masters as a means of stark caricature. It was in this form, the most extreme possible, that character and moral differentiation were introduced into the realm of realistic depiction.
