Simplified composition means that artists refine and summarize the internal order of objective objects, break the original order and structure for integration and reorganization, and convey inner vision through paper and pen as the media.Simplified composition still has important research significance for contemporary easel painting.Balthus's works have simplified composition meaning. He believes that painting is not reproduction, but to explore the secret of the heart and express the inner vision by relying on objective objects.He has extensively absorbed Japanese Ukiyo-e, modern stage art, medieval murals, Renaissance art, Chinese poetry and so on, presenting a unique artistic style.Modelling language he is committed to using "complanation" and "gradient and drama", "geometry induction and visual guide", "golden and contrast" way to simplify the internal order and the objective image, making dramatic atmosphere, strengthen the narrative and surrealism drawing, the work is full of psychological hint and metaphor.

Based on the case of Balthus, this paper makes an in-depth exploration and study of the simplified composition language in Balthus's modeling language by studying Balthus's picture album, painter's dialogue and combing the painting theories of contemporary painters and related theoretical works.By analyzing Balthus's works and combining the composition, techniques and rules in his artistic creation, this paper systematically discusses the significance and function of simplified structural modeling language.
