A plausible impssibility is always preferable to an unconvincing possibility
-Aristotle

IMPOSSIBLE FIGURES: The rationality of solid geometric figures goes awry with impossible figures, those which can be drawn but cannot exost in three-dimensional space. Many of the most puzzling, and at the same time dazzlingly beautiful, aspects of Escher's work arise from the fact that he breaks the boundaries of dimensionality. He paints, on a two-dimensional surface, pictures of four-dimensional objects as they would appear in three dimensional space. One overt example of this is Neckar's Cube (#430). Escher preferred to veil impossible structures beneath typical, mundane format which he felt added to the mystery of such figures. Waterfall (#439), for example, is a superficially ordinary scene whose impossibility is based upon the Penrose Triangle. Escher's impossible scenes create an inconsistancy of the whole, while each individual aspect is perfectly reasonable.
