Artist: Jan Steen, 'The Harpsichord Lesson', 1660x69. An example of the seventeenth-century 'picture within a picture' technique used here by Steen himself, and with added meaning. A young girl receives her lesson from an older man, while cupids appear in the image behind her. Thus, Steen hints, the scene is rather less innocent than it seems. Vermeer used the picture within a picture in much the same way.
