Erigena

Erigena, Johannes Scotus, a scholar and metaphysician of the ninth century who was born in Ireland. He lived chiefly in France, where Charles the Bald placed him at the head of the palace school, and employed him to translate the Greek of the supposed Dionysius the Areopagite into Latin, and to compose a controversial treatise on Predestination and Freewill. This and his De Divisione Natures were condemned by the Church on the ground of their pantheism. The place and date of his death are unknown. He is ranked as one of the founders of Realism.
