|Gabriël Metsu (1629-1667) dutch "A Woman Artist" private collection|
This painting is believed to depict Metsu's wife Isabella de Wolff (1631-1718) who often posed for him. Also known as "Le Corset Rouge" it is dated 1661-4. It should be noted that de Wolff was not simply posing as an artist, but she really was an artist, or at least, she was trained as an artist. Isabella de Wolff's mother, Maria de Grebber, was one of the famous De Grebber painting family from Haarlem, and she and her father and brothers were all practicing artists.
