Georges Chastellain (born c. 1405 or c. 1415, Aalst, Brabant died 1475, Valenciennes, Burgundian Hainaut), Burgundian chronicler and poet, was a native of Aalst in Flanders. In spite of excessive partiality to the Duke of Burgundy, Chastellain's historical works are valuable for the accurate information they contain. As a poet he was famous among his contemporaries. He was the great master of the school of grands rhétoriqueurs, whose principal characteristics were fondness for the most artificial forms and a profusion of latinisms and graecisms.
