Jupiter and Antiope
From The Art and Popular Culture Encyclopedia
In Greek mythology, Antiope was the name of the daughter of the river god Asopus. Her beauty attracted Zeus, who, assuming the form of a satyr, took her by force. In postclassical art, the story is depicted in paintings and prints as a scene of voyeurism.
Famous renderings of the subject include those of Watteau, a print by Rembrandt, a painting with a very hairy Jupiter by Spranger, another painting  by Hans von Aachen and a painting by Goltzius, who shows a lactating Antiope.
