When Rubens was 53 he married a girl 16–Hélène Fourment. He couldn’t take his eyes off her–so beautiful and charming was she. Nor his brush. She started appearing everywhere in his paintings. She was the Venus in The Feast of Venus (Kunsthistorisches Museum, Vienna), and The Judgment of Paris (Prado, Madrid); and she was at least two of the Graces in The Three Graces (Prado, Madrid).
This is a portrait of her wrapped in fur during what might be a break in a modelling session for the very picture above. Here Rubens has turned her into a Venus Pudica.
