It is very rarely granted even to Nature herself to produce anything absolutely perfect in every part.
Errors accumulate in the sketch and compound in the model.
Nothing overshadows truth so much as authority.
I certainly consider a great appreciation of painting to be the best indication of a most perfect mind.
A man can do all things if he will.
Painting is possessed of divine power, for not only does it make the absent present, but also makes the dead almost alive.
