  Beauty is only found in the objects of sight (oggetti del viso), such as beautiful forms and shapes and beautiful pictures, the perfect symmetry of the parts with the whole, well-proportioned limbs, beautiful colors and clear light, the sun, the moon and the stars, and the heavens in all their splendor. This grace exists in objects of sight by reason of their spiritual nature, and it is the custom to enter through the clear and spiritual eyes, to delight our soul and move it to a love of such an object; and this is what it is that we call beauty. It is also found in objects of hearing, such as beautiful oratory, voices, speech, song music, consonance, proportion and harmony. For in the spiritual nature of these things is found grace which moves the soul to delight and to love through the medium of the spiritual sense of hearing. Thus grace and beauty are found among beautiful things that are endowed with a spiritual nature (sensi   spirituali).[22]
