"He who wishes to be rich in a day will be hanged in a year."

"The painter who draws merely by practice and by eye, without any reason, is like a mirror which copies everything placed in front of it without understanding."

"The memory of all that is past is as nothing in comparison with the knowledge of what is to come."

"The mind of the painter is a copy of the divine mind, since it operates freely in creating countless forms of animals, plants, fruits, landscapes, countrysides, ruins, and other things."

"Study without desire spoils the memory, and it retains nothing that it takes in."
