La Galaizière est créé chancelier par Stanislas

This 1778 history painting depicts the ceremonial investiture of Antoine-Martin Chaumont de la Galaizière as Chancellor of Lorraine by Stanislas Leszczyński, the former King of Poland who served as Duke of Lorraine from 1737 until his death in 1766. The subject was already historical by the time Vincent painted it—Stanislas had died twelve years earlier—making this a commemorative work celebrating the legal and administrative history of a duchy that had been formally united with France in 1766. The Museum of the History of France at Versailles holds this canvas, situating it within the comprehensive documentary project of French historical painting. Vincent was at this point a young painter of thirty, producing his first major history paintings; the large compositional challenge and the need to populate a formal ceremony with accurately rendered figures in period costume tested his academic skills systematically.

Large-format history painting on canvas requiring the management of multiple figures in a ceremonial spatial arrangement. Vincent organises the composition around the central investiture gesture, with attendant figures arranged in depth to create spatial recession. The period costumes and architectural setting are rendered with historical attention, demonstrating the research component expected of serious history painting.
