It is better to imitate ancient than modern work.

Make your work to be in keeping with your purpose

It's easier to resist at the beginning than at the end.

Every now and then go away, have a little relaxation, for when you come back to your work your judgment will be surer. Go some distance away because then the work appears smaller and more of it can be taken in at a glance and a lack of harmony and proportion is more readily seen.

A beautiful body perishes, but a work of art dies not.

You can have no dominion greater or less than that over yourself.
