No other artist blends rational and mathematics with whimsical and imagination better than M. C. Escher. From renowned crystallographers to art collectors, across decades and generations, Escher’s work prompted a rare and wide-reaching appeal that persists even today.  

"The graphic artist ... is like a blackbird singing at the top of a tree.  He repeats his song over and over again, and it is complete in each print he makes.  The more that are required, the better he is pleased." - M.C. Escher, 1957
