M.C. Escher the graphic work

I have a book about M.C. Escher and all the writing in it is actually done by the artist himself, which I find surprising and fantastic. Art historians put together biographies and commentaries on artists, but the artists don’t seem to have much say. Then again perhaps this is rightly done because the artist is concerned with visual presentation and not necessarily literature. I still find great joy in seeing an artist concerned with his audience so much that he would take time to write himself about the art he created.
M.C. Escher stated this discovery: after searching and devouring the techniques of drawing, doing work just to discover and better techniques become less important. Only once the techniques are understood fully can you start communicating thoughts. I believe this is a great view to have in Life Drawing two. We are still developing technique to make it second nature so that later in life we can communicate ideas without worrying about our shoddy technique hindering us.
I was also surprised to hear Escher say the perfect image in the mind is much different than the visual image an artist creates; they will never be able to bring about exactly what they expect. Even coming from someone that seemed to have mastered the graphic arts, Escher still could not perfect what was in his minds eye. But he did realize visual image can be refined into something unexpected. Once it's visual state is made the rest is like a relaxing dance when the technical skills that have been mastered take over and give the mind a rest.
Just as a ending though M.C. Escher states something that surprised him: Though you produce a work that seems impersonal in nature in order to express a simple idea or appeal to a group of individuals, it seems no one can express or write a description of the work suitable accept the artist himself
