Visions of Symmetry is a trip into the mind of a creator who continues to captivate the world. Doris Schattschneider’s classic is the most penetrating study of Escher’s work in existence, and the one most admired by mathematicians and scientists. Schattschneider asks, ‘How did he do it?’. She answers the question by meticulously analysing Escher’s notebooks. Visions of Symmetry includes many of Escher’s masterworks, as well as hundreds of lesser-known examples of his work. This new edition also features an illustrated epilogue by the author that reveals new information about Escher’s inspiration and shows how his ideas on symmetry have influenced mathematicians, computer scientists and contemporary artists.
