GILLES LI MUISIS or LE MUISET (c. 1272-1352), French chronicler, was born probably at Tournai, and in 1289 en tered the Benedictine abbey of St. Martin in his native city, be coming prior of this house in 1327, and abbot four years later. Gilles wrote two Latin chronicles, Chronicon majus and Chronicon minus, dealing with the history of the world from the creation until 1349. This work, ed. J. J. de Senet, in Corpus chronicorum Flandriae, tome ii. (Brussels, 1841), continued by another writer to 1352, is valuable for the history of northern France and Flan ders during the first half of the 14th century. Gilles also wrote some French poems, and these Poesies de Gilles li Muisis have been published by Baron Kervyn de Lettenhove (Louvain, 1882). See A. Molinier, Les Sources de l'histoire de France, tome iii. (1903).
