Final answer:
Henri Matisse's Luxe, calme et volupté is an example of painterly brushwork, as is Richard Diebenkorn's Cityscape #1, both characterized by their expressive, loose brushstrokes. Works by Lorenzetti, such as Effects of Good Government in the City, do not exemplify painterly brushwork, as they come from the early Renaissance and show precise lines and clear storytelling.
Step-by-step explanation:
Among the artworks mentioned, an example of painterly brushwork can be observed in Henri Matisse's Luxe, calme et volupté, painted in 1904. This work is noted for its use of vibrant colors and loose, flowing brushstrokes that convey an expressive quality, central to the painterly technique. The use of painterly brushwork allows for a more expressive and fluid approach to painting, as opposed to a tightly controlled and detailed style. This technique is evident in the spontaneous and active brushstrokes of Impressionism, where quick brushstrokes capture fleeting effects of color, light, and atmosphere. Additionally, Richard Diebenkorn's Cityscape #1 showcases a more fluid and expressive use of the painterly method, where the brushwork is also used to blur the line between realism and abstraction.
It is important to note that the works of Lorenzetti, such as Effects of Good Government in the City, are frescoes from the early Renaissance period and do not employ a painterly brushwork, but rather exhibit a more precise and didactic style, storytelling with clear delineation.
