When you hear the name M.C. Escher, what comes to mind? Wild and surreal tessellations of shapes turning into birds turning into people? Impossible houses the defy gravity with waterfalls rising from nowhere? How about buildings with interconnected staircases coming from all sides?Escher's artwork and style is some of the most unique and identifiable in the world, mostly due to his love for mental imagery and so-called impossible art.But how much do you know about the gifted and mysterious artist, really? Did you know his life was plagued with illness and fleeing from political struggles in Europe? Or that he produced the vast majority of his work while traveling through the Italian countryside, even though he was Dutch?
