"It is the intense personal character which, I think, gives the superiority to Titian's portraits over all others, and stamps them with a living and permanent interest. Of other pictures you tire, if you have them constantly before you; of his, never. For other pictures have either an abstracted look, and you dismiss them, when you have made up your mind on the subject as a matter of criticism; or an heroic look, and you cannot be always straining your enthusiasm; or an insipid look, and you sicken of it. But whenever you turn to look at Titian's portraits, they appear to be looking at you; there seems to be some question pending between you, as though an intimate friend or inveterate foe were in the room with you; they exert a kind of fascinating power; and there is that exact resemblance of individual nature which is always new and always interesting, because you cannot carry away a mental abstraction of it, and you must recur to the object to revive it in its full force and integrity. I would as soon have Raphael's, or most other pictures, hanging up in a collection, that I might pay an occasional visit to them: Titian's are the only ones that I should wish to have hanging in the same room with me for company!"
