The regular division of the plane into congruent figures evoking an association in the observer with a familiar natural object is one of these hobbies or problems...I have embarked on this geometric problem again and again over the years, trying to throw light on different aspects each time. I cannot imagine what my life would be like if this problem had never occurred to me; one might say that I am head over heels in love with it, and I still don't know why.

For me it remains an open question whether [this work] pertains to the realm of mathematics or to that of art.

I never got a pass mark in math ... Just imagine - mathematicians now use my prints to illustrate their books.

By keenly confronting the enigmas that surround us, and by considering and analyzing the observations that I had made, I ended up in the domain of mathematics. Although I am absolutely without training in the exact sciences, I often seem to have more in common with mathematicians than with my fellow artists.

A woman once rang me up and said, 'Mr. Escher, I am absolutely crazy about your work. In your print -Reptiles- you have given such a striking illustration of reincarnation.' I replied, 'Madam, if that's the way you see it, so be it.'

Originality is merely an illusion.

He who wonders discovers that this in itself is wonder.
