Francisco Goya

I have had three masters, Nature, Velasquez, and Rembrandt.

The dream of reason produces monsters. Imagination deserted by reason creates impossible, useless thoughts. United with reason, imagination is the mother of all art and the source of all its beauty.

Painting, like poetry, selects in the universe whatever she deems most appropriate to her ends. She assembles in a single fantastic personage, circumstances and features which nature distributes among many individuals. From this combination, ingeniously composed, results that happy imitation by virtue of which the artist earns the title of inventor and not of servile copyist.

Monsters are the result of the sleep of reason.
