Johannes Scotus Eriugena
Johannes Scotus Eriugena was educated in Ireland. He moved to France (about 845) at the invitation of Carolingian King Charles the Bald. He succeeded Alcuin of York (735–804), the leading scholar of the Carolingian Renaissance, as head of the Palace School. The reputation of this school increased greatly under Eriugena's leadership, and he was treated with indulgence by the king. Whereas Alcuin was a schoolmaster rather than a philosopher, Eriugena was a noted Greek scholar, a skill which, though rare at that time in Western Europe, was used in the learning tradition of Early and Medieval Ireland, as evidenced by the use of Greek script in medieval Irish manuscripts. He remained in France for at least thirty years, and it was almost certainly during this period that he wrote his various works.
