Bruno Ernst wrote popular books about visual puzzles, impossible constructions and the work of M. C. Escher, often explaining the geometry behind images that appear to defy ordinary space. He is best known in English for The Magic Mirror of M. C. Escher, which surveys Escher's prints and drawings while discussing recurring ideas such as tessellation, reflections, perspective, infinity and impossible architecture. Ernst's approach sits between art book and mathematical recreation: the images remain central, but explanatory text helps readers understand how visual tricks are constructed. His books are therefore especially relevant to readers interested in Escher, optical illusion, recreational mathematics and mathematical art rather than conventional art history alone. Read more Less
