Swearing-in of Isabeau of Bavaria as regent of the kingdom. Miniature on vellum skin (chips). H. 70 mm; W. 100 mm. Under glass, marquise and gilded wood frame. Probably 18th-19th centuries The kneeling Queen (1371-1435), probably at Notre-Dame de Paris, is joined on either side by the Archbishop of Paris and the Provost of Merchants Jean Juvénal des Ursins, sword at her side. All three are holding hands in front of a large open book, a bible (?). In the background, two ladies-in-waiting wearing hennines; on the right, a coat-of-arms topped by a helmet bears a crenellated tower (?). From 1400, King Charles VI, Isabeau's husband, was unable to reign due to his insanity. His brother Louis, Duke of Orleans (assassinated in 1407) and his cousin Jean de Bourgogne offered to govern the kingdom in his place. But it came to be accepted that a regency could fully assume the role of a living but incapacitated monarch. In 1408, Juvénal des Ursins, Advocate General at the Parliament of Paris, entrusted the regency to the Queen. The scene depicted here illustrates that moment. From then on, Isabeau played a consensual role with the factions at court.
