A Treatise on Painting (1651); "The Paragone"; compiled by Francesco Melzi prior to 1542, first published as Trattato della pittura by Raffaelo du Fresne (1651)
Context: Painting is poetry which is seen and not heard, and poetry is a painting which is heard but not seen. These two arts, you may call them both either poetry or painting, have here interchanged the senses by which they penetrate to the intellect.
