August III, Elector of Sachsen, King of Poland

Augustus III, Elector of Saxony and King of Poland (reigned 1733–1763), was among the most significant royal patrons of art in eighteenth-century Europe — his Dresden court assembled one of the greatest painting collections of the era, which became the foundation of today's Gemäldegalerie. Mengs's father, Ismael Israel Mengs, was court painter in Dresden, which explains how Anton Raphael Mengs received his formation and early commissions under Augustus III's patronage. A portrait of Augustus III by Mengs thus has particular biographical resonance, representing the royal patron who shaped the painter's early career. The Nationalmuseum in Stockholm's possession of this portrait reflects the complex collection histories of Northern European aristocratic art.

Elector-king portraiture required the full apparatus of dynastic imagery: crown of Poland, Elector's hat, Order of the White Eagle, armour or rich mantle. Mengs would have had to manage this accumulation of symbolic attributes while maintaining the compositional coherence he favoured, a challenge more Baroque in character than his theoretical preferences normally admitted.
