Ask the beauty of the earth, ask the beauty of the sea, ask the beauty of the ample and diffused air. Ask the beauty of heaven, ask the order of the stars, ask the sun, which with its splendor brightens the day; ask the moon, which with its clarity moderates the darkness of night. Ask the beasts that move in the water, that walk on the earth, that fly in the air: souls that hide, bodies that show themselves; the visible that lets itself be guided, the invisible that guides. Ask them! All will answer you: Look at us, we are beautiful! Their beauty makes them known. This mutable beauty, who has created it if not Immutable Beauty?" ■ St. Augustine, Sermo CCXLI, 2: PL 38, 1134).
