Ceilings become floors, and up becomes down in M.C. Escher’s incredible “High and Low,” which depicts two angles of the same scene woven together to create a single vantage point. Combining mathematical logic and visual improbability in works of dazzling symmetry, Escher (1898 – 1972) was a graphic artist who lacked mathematical training, but used intuitive mathematical principles which were so advanced that his art was studied by mathematicians, scientists and crystallographers. Disliking flat images, Escher created 150 works that explored implausible, multi-dimensional architecture.
