This miniature by Jean Michelin is one of eighty-eight portraits of German and other families first recorded in Queen Caroline's Closet at Kensington Palace. The sitter, George William, Duke of Brunswick-Celle, owed his place in this assemblage of the progenitors of the Hanoverian monarchs to the fact that he was the father-in-law of George I of England. His daughter, Sophia Dorothea of Celle, married George Ludwig, Elector of Hanover, who became George I of England in 1714. Jean Michelin is said to have been born in Langres France and died on the island of Jersey. He became a member of the Académie Royale, Paris, in 1660 and worked for the Hanoverian court from 1668 until 1686. Here he presents the Duke of Brunswick-Celle with the authority of a Roman commander, wearing a light blue cloak over his tunic. Inscribed on the gessoed reverse: No. 30 George Guillaume Due de Broun: et Lune:
