During the Middle Ages, Western theologians such as Anselm of Canterbury, John Scotus Eriugena, Bonaventure, Thomas Aquinas, Nicholas of Cusa, and Bernard of Clairvaux touched upon themes such as "the idea of beauty, the vision of God, the image of Christ, the iconodule-iconoclast conflict, and the strong presence of personally grounded and poetic doxologies".
