Jean de Vignay (c. 1282/1285 – c. 1350) was a French monk and translator. He translated from Latin into Old French for the French court, and his works survive in many illuminated manuscripts. They include two military manuals, a book on chess, parts of the New Testament, a travelogue and a chronicle.

Primat was a French Benedictine monk and historian of the abbey of Saint-Denis near Paris. He composed two histories of France with a royal focus, one in Latin and the other in Old French. His Latin chronicle covers the years 1248 to 1277 but now survives only in an Old French translation and in excerpts incorporated into the works of others. It contains a detailed account of the reign of Louis IX, making it one of the most important contemporary sources for that reign. His French chronicle, the Roman des rois, covers the entire history of France down to 1223. It was completed around 1274 for Philip III and its presentation copy is extant. It is the earliest version of what would become the Grandes Chroniques de France, the first official history of France.
