A talented associate of the Master of the Bible of Jean de Sy painted nine of the ten large miniatures of the Grandes Heures, together with their bas-de-page scenes, as well as most of the small miniatures of the original campaign. Given his significant contribution, he is named the Master of the Grandes Heures. Active in Paris c. 1350-1380, he illuminated manuscripts for Charles V in the 1370s. He followed closely the Jean de Sy Master’s compositions, figure and facial types, palette and painting technique.
