Plotinus Ennead I.6: On Beauty - The Enneads of Plotinus

This is probably the best known and most influential treatise of Plotinus, especially for Renaissance artists and thinkers. The treatise is at once a philosophical search for the nature of the divine and at the same time an encouragement to the individual to aspire to this goal by taking his start from the beauty which is experienced in this world; for it is an image of transcendent beauty.
