While the Church Fathers never produced any important astronomical works, like most Christian theologians they were aware of the fact that the wonder inspired by the vision of the heavens fostered feelings of profound devotion towards the Supreme Being, Creator of such a masterwork: "Coeli enarrant gloriam Dei" ("The heavens declare the glory of God") was the motto that pervaded Christendom. Hymns of praise were offered up to God even by the genial inventors of the spectacular planetary machines that reproduced the regular movement of the stars. The most illustrious representatives of the arts contributed to the battle to purge the skies of the crowd of pagan deities, replacing them with the image of God enthroned, surrounded by the angelic orders, impressing movement on the universe with a mere gesture of His hand. Cosmology and theology walked hand in hand in an era that may not have seen any spectacular progress in man's knowledge of astronomy, but that helped to strengthen the classical vision of a universe created for man and made to his measure. This vision is to be found both in Hildegard of Bingen's mystic cosmology and in Dante's Divine Comedy.
