Perfection is no small thing, but it is made up of small things.
Art is a shadow of Divine perfection.
A good artist ought never to allow impatience to overcome his sense of the main end of art - perfection
Trifles make perfection but perfection is not a trifle
Good painting is nothing else but a copy of the perfections of God and a reminder of His painting. Finally, good painting is a music and a melody which intellect only can appreciate, and with great difficulty.
