The prototype of the second portrait exists in two versions, one oil on canvas, 44 x 36.5 cm and the other in pastel, 29 x 25.5 cm, both in the Staatliche Schlösser und Gärten, Berlin (Johann Heinrich Schröder (1757-1812), Preussische Porträts, Verein Historisches Partez e.V. Stiftung Schlösser und Gärten Potsdam-Sanssouci, 1994, pp.53/4, under n041) and was engraved by Ferdinand Ruyscheweyh in 1802 (op. cit., p.54, under n041).
The sitter, daughter of Carl, Duke of Mecklenburg-Strelitz and Friederike, Princess of Hessen-Darmstadt, married Friedrich Wilhelm III, King of Prussia (1770-1840) in 1793. She was one of the most respected women of her time, known for her courageous attitude during the Napoleonic occupation. Her fame led to numerous versions and copies of Schröder's portrait.
