Ugo Mochi quotes:

For years I study. I look long at olive trees, all gray and silver, and watch the sunlight. Ah, yes, I am ver' lazy, but I see after I look long that it is perspective that give it this quality. Perspective, and absolute faith to the subject.

I use a special tool. I make it myself; very sharp steel point and a handle like a pencil. For me it is a pencil. Maybe I have a special talent, a feeling you might say that lets me control it, to express my ideas as though I were sketching black on white.

One must have a thorough knowledge of anatomy and a good perception of depth for silhouette work. Otherwise they resemble those childish picture cards, snipped out by some fool who doesn't know what he is trying to do.

It is most difficult to acquire the, how shall I say? the 'depth' of a subject in composition in silhouette.

You cannot do silhouettes in fantasy. Ah, no, you must be faithful. It is, the art, a, what you call, paradox. It is always that you must be simple, and then, if you are simple, you will stimulate the imagination of the observer.
