John Scotus Eriugena 815 – 877

John Scotus Eriugena was an Irish theologian and Neoplatonist philosopher active at the court of the Carolingian king Charles the Bald. He produced the first Latin translation of the writings of Pseudo-Dionysius the Areopagite, transmitting Eastern Neoplatonic theology to the Latin West. His magnum opus, the Periphyseon, divides nature into four categories ordered by whether they create or are created, and develops a daring synthesis of Christian doctrine with Greek philosophical metaphysics. His work was condemned in the thirteenth century but later inspired Nicholas of Cusa and the speculative tradition.
