Dante Alighieri
Dante Alighieri is the author of, among other works, the Inferno, the Purgatorio, and the Paradiso, together known as the Divine Comedy. All Columbia College students read at least the Inferno in Lit Hum. Dante had some mild problems with the Church, but beware ye who enter into a teleological argument that this represented some kind of early Protestantism. Oh, and he championed the Italian vulgate over Latin, which was far more helpful to 13th century courtesans than to students reading everything in English translation anyway.
