"Yet more formidable, perhaps, is Anna Dorothea Therbusch, whose self-portrait, on loan from the Gemäldegalerie in Berlin, shows her as a learned matriarch sporting a fantastic monocle - drawing attention to her eye, and thus the artist's gaze. Therbusch defied convention by tackling the male nude and leaving her family to pursue her art. Her first submission to the Académie Royale in Paris was turned down because the quality of the colour and strokes must, it was felt, have been the work of a man."
