Isidore's great medieval encyclopedia, now known as Etymologies, or the Origins of Words, made him "the chief authority of the Middle Ages, and the presence of his book in every monastic, cathedral and college library was a main factor in perpetuating the state of knowledge and the modes of thought of the late-Roman world" (PMM 9).
