Almost like a 17th century Dutch portrait, this much more casual image of a young woman at a window — one of four related paintings of the same model — allows the subject to gradually emerge from darkness into gentle illumination from the window.
Homer’s painterly, seemingly casual brush marks define the elements in the painting with confidence and economy. There is something especially appealing to me about the simplicity of the plants on the windowsill and the suggestion of landscape beyond.
