Guillaume de Nangis

Who was Guillaume de Nangis?

Guillaume de Nangis, also known as William of Nangis, was a French chronicler.

William was a monk in the Abbey of St.-Denis. About 1285 he was placed in charge of the abbey library as custos cartarum, and he died in June or July 1300. Having doubtless done some work on the Latin manuscripts on which the Grandes Chroniques de France are based, William wrote a long Chronicon, dealing with the history of the world from the creation until 1300. For the period before 1113 this work merely repeats that of Sigebert of Gembloux and others; but after this date it contains some new and valuable material. The chronicle had later continuations by other authors, with the "second continuation", mainly by Jean de Venette, taking events up to 1368.

William's other writings are: Gesta Ludovici IX; Gesta Philippi III, sive Audacis; Chronicon abbreviatum regum Francorum; and a French translation of the same work written for the laity. Making use of the large store of manuscripts at Saint Denis, William was a compiler rather than an author, and with the exception of the latter part of the Chronicon his writings do not add materially to our knowledge of the time. In his Gesta Ludovici IX he included a letter from Sempad the Constable to Henry I of Cyprus.
