Ch'un marmo solo in se non circoscriva
Col suo soverchio; e solo a quello arriva
La man che ubbidisce all'intelletto.
(The best artist has in himself no concept
in a single block of marble not contained;
only the hand obeying mind will find it.)
-- Michelangelo, as quoted
by Erwin Panofsky in
Idea: A Concept in Art Theory
