EUSTACE OF ARRAS, called Buisine. — Franciscan theologian, born probably at Arras about 1225, died 7 April 1291. At the University of Paris he was a pupil of St. Bonaventure and of Gilbert of Tournai. He is remembered as a most listened-to preacher, and his nickname Buisine (Trumpet) refers to his oratorical triumphs. In May 1271 he was summoned by St. Louis of France at Viterbo in the company of the cardinals assembled in conclave for the election of the new pope. In 1272–73 he was again at Paris and then in his own religious province, especially in the convent of Rouen. Martin IV appointed him bishop of Coutances in 1282.
Among his writings, almost entirely unpublished and preserved in the libraries of Paris, Reims, Basel, the Vatican and the Antoniana in Padua, are noted the commentaries Super Libros Ethicorum and In libros Sententiarum, the Quaestiones quodlibetales (some of which were edited at Quaracchi in 1883 in the work De humana cognitionis ratione anecdotae quadam, pp. 183–95) in France Franciac., 13 [1930], pp. 147–52); various other philosophical and theological treatises and numerous sermons.
