His successors likewise invited the Irish teachers to their court. Louis the Pious was the patron of the Irish geographer Dicuil, Lothair II stood in a similar relation to the Irish poet and scribe Sedulius Scottus, founder of the school at Liège, and Charles the Bald equalled his grandfather in his affectionate esteem for the Irish teachers. Under him Elias taught at Laon, Dunchad at Reims, Israel at Auxerre, and the greatest of all the Irish scholars, Johannes Scotus Eriugena, was head of the palace school.
