Mary Shelley, wife of Percy Bysshe Shelley and author of Frankenstein, wrote of Brunelleschi’s Gates of Paradise in Florence: “Let us turn to the gates of the Battistero, worthy of Paradise. Here we view all that man can achieve of beautiful in sculpture, when his conceptions rise to the height of grace, majesty, and simplicity. Look at these, and a certain feeling of exalted delight will enter at your eyes and penetrate your heart.”
