Virgin of the Rocks
There is no real consensus on the painting's subject, date, history or purpose. It shows an unknown woman gazing downward while her hair fills the frame behind her. Many theories regarding the subject have been proposed, such as the painting being a sketch for an uncompleted painting of Saint Anne; a study for the London version of "The Virgin of the Rocks" or "Leda and the Swan" painting, now a lost work; or—for its aesthetic value—a purposefully unfinished painting.
