Since the time of Charlemagne, Irish scholars had a considerable presence in the Frankish court, where they were renowned for their learning. The most significant Irish intellectual of the early monastic period was the 9th century Johannes Scotus Eriugena, an outstanding philosopher in terms of originality. He was the earliest of the founders of scholasticism, the dominant school of medieval philosophy. He had considerable familiarity with the Greek language, and translated many works into Latin, affording access to the Cappadocian Fathers and the Greek theological tradition, previously almost unknown in the Latin West.
