Gilles Li Muisis

Gilles Li Muisis (or Le Muiset) (c. 1272 – 15 October 1352) was a French chronicler and poet.

In 1289 he entered the Benedictine abbey of Saint-Martin in his native city, becoming prior of this house in 1327 and abbot four years later.

He only secured the latter position after a contest with a competitor, but he appears to have been a wise ruler of the abbey.

This work, which was expanded by another writer to encompass 1352, is valuable for containing the history of northern France and Flanders in the first half of the 14th century.

It is published by J. J. de Smet in the Corpus chronicorum Flandriae.
