Therbusch, Anna Dorothea (Vorlage): Porträt Carl Franz von Irwing

The work showcases a use of chiaroscuro, evident in the contrast between light and dark areas, which was a characteristic technique of the period. The original painting by Therbusch (1778) was later engraved by J. C. Kruger (1787).

Originally part of the Diepenbroick-Grüter collection, the portrait was acquired by the Berlin Museum in 1965. The engraving is documented in literature, though the original painting's whereabouts are unknown.

Created during the late 18th century, the portrait reflects the artistic and social conventions of the time, blending formal representation with symbolic elements like the coat of arms.

While the original painting's location is unknown, the engraved version, documented in scholarly journals (e.g., Eckhart Berckenhagen, 1987), contributes to the historical record of Therbusch's oeuvre and 18th-century portraiture techniques.
