From the Chronicles of Froissart:
JEAN FROISSART, the most representative of the chroniclers of the later Middle Ages, was born at Valenciennes in 1337. The Chronicle which, more than his poetry, has kept his fame alive, was undertaken when he was only twenty; the first book was written in its earliest form by 1369; and he kept revising and enlarging the work to the end of his life. In 1361 he went to England, entered the Church, and attached himself to Queen Philippa of Hainault, the wife of Edward III, who made him her secretary and clerk of her chapel. Much of his life was spent in travel. He went to France with the Black Prince, and to Italy with the Duke of Clarence. He saw fighting on the Scottish border, visited Holland, Savoy, and Provence, returning at intervals to Paris and London. He was Vicar of Estinnes-au-Mont, Canon of Chimay, and chaplain to the Comte de Blois; but the Church to him was rather a source of revenue than a religious calling. He finally settled down in his native town, where he died about 1410.
