Portrait de Louis Jean Marie de Bourbon, duc de Penthièvre (1725-1793)

Louis Jean Marie de Bourbon, Duc de Penthièvre, was one of the most prominent French princes of the mid-eighteenth century — the last surviving legitimate grandson of Louis XIV and a figure of great wealth and charitable reputation. Nattier's 1750 portrait of him at the Fondation Bemberg in Toulouse captures the duke at twenty-five, already a major figure in French court life. The Fondation Bemberg holds an exceptional collection of French and Italian paintings in the Hôtel d'Assézat in Toulouse, assembled by the Swiss collector Georges Bemberg in the twentieth century. A Nattier portrait of this historical significance is a natural centrepiece for such a collection. The duke's later reputation for generosity — he distributed his great wealth extensively to charitable causes — makes this early portrait historically poignant.

Military and high noble portraiture by Nattier required formal dress and heraldic accessories appropriate to the subject's rank. The duke's Order of the Holy Spirit sash or equivalent decorations would be rendered with the precision needed for their symbolic legibility, while the face — by 1750 Nattier's most assured technical territory — would carry the composed confidence of a senior prince.
