Michelangelo did not, then, stress the literal imitation of nature. Michelangelo disliked this trend in art, since this was an area where "one cannot make fixed rules, making figures as regular as signposts" (Blunt 75). DÃ…rer relied on precise proportions in representing the human figure, and Michelangelo found his work uninteresting. Flemish painting was equally distasteful, since their painting is "expressly to deceive the outer vision ... and all this, although it may appear good to some eyes, is done truly without reason or art, without symmetry or proportion, and without attention to selection or rejection" (Clements 207-208). For Michelangelo, the function of art was to represent ideal beauty. As such, Michelangelo portrayed figures which are not engaged in any particular activity -- the stance of the David is twisted, and the manner in which he holds his slingshot would make any action impossible. The Virgin is portrayed as a young woman because her beauty is timeless. The David and the Virgin are ideal types, not particular individuals.
