This powerful and haunting painting looks like a scene from mythology, or a dream. Its title reveals the artist’s meaning: a shepherd, resting, dreams of a group of dancing naked women on a riverbank. The vivid, unnatural colors bring an electric charge to the scene, making it look surreal. The careful composition and deliberate symmetry lend a formal unity that underlines the subject as symbolic, a scene imbued with meaning. Some critics of the time banned the painting, citing excessive eroticism.
