William Durandus the Younger
Canonist, nephew of William Durandus the Elder, died Cyprus, 1328.
He succeeded his uncle as Bishop of Mende, and was sent by Pope John XXII and King Charles IV of France on an embassy to the Sultan Orkhan at Brusa, to obtain more favorable conditions for the Latins in Syria.
By command of Pope Clement V he wrote a treatise, in three books, on the canonical process of summoning and holding general councils, with many quotations and illustrations from the Fathers and from church history, together with attacks on various abuses common in the 14th century among ecclesiastical persons.
