He who improvises can never make a perfect line of poetry.
Art is stronger than Nature
I think I am beginning to learn something about painting.
It is not bright colors but good drawing that makes figures beautiful.
From the example of the past, the man of the present acts prudently so as not to imperil the future.
Those who are compelled to paint by force, without being in the necessary mood, can produce only ungainly works, because this profession requires an unruffled temper.
