Mauritius Cornelius Escher, perspectivas e ilusiones

Did you know that Escher was not good at Math? that he had a hard time at school? below I quote from the opening to Escher's fascinating biography, but there is lots more in its original website: http://www-history.mcs.st-andrews.ac.uk/Biographies/Escher.html

<<  Maurits Escher was always referred to by his parents as Mauk. (...) Maurits attended both elementary and secondary school in Arnhem, the Netherlands, between 1912 and 1918, where he failed to shine in many of his subjects, but exhibited an early interest in both music and carpentry.

People expressed the opinion that he possessed a mathematical brain but he never excelled in the subject at any stage during his schooling and treated the subject with some considerable unease. He wrote [7]:-

At high school in Arnhem, I was extremely poor at arithmetic and algebra because I had, and still have, great difficulty with the abstractions of numbers and letters. When, later, in stereometry [solid geometry], an appeal was made to my imagination, it went a bit better, but in school I never excelled in that subject. But our path through life can take strange turns. >>

 

For a really complete overview of his art work, the National Gallery of Art in Washington DC presents a fabulous collection of Escher's art in its site: http://www.nga.gov/collection/gallery/ggescher/ggescher-main1.html
