da Vinci on drawing

"O writer! What words can you find to describe the whole arrangement as perfectly as is done in this drawing? For lack of true knowledge you describe it confusedly and convey little knowledge of the true shapes of things...My advice it not to trouble yourself with word unless you are speaking to the blind."

Leonardo da Vinci on the superiority of drawing to writing. Taken from the biography of da Vinci by Charles Nicholl.
