A 1908 portrait by Belgian Neo-Impressionist Théo van Rysselberghe, featuring a sitter in a dark hat and ruffled collar, rendered with expressive, rhythmic brushwork.

Théo van Rysselberghe, a central figure in the Belgian Neo-Impressionist movement, painted this portrait of Madame Monnon in 1908. By this stage in his career, the artist had moved away from the strict, scientific pointillism of his earlier years, adopting a freer, more fluid application of paint. This work demonstrates his mature style, where short, rhythmic brushstrokes construct form and light without the rigid adherence to colour theory that defined his earlier output.

The subject is depicted with a direct, unvarnished gaze. She wears a dark, textured garment with a prominent white ruffled collar, which provides a stark contrast to the deep purples and blues of her attire. Her head is covered by a dark hat, framing a face rendered with sensitivity and attention to the effects of age. The background is composed of loose, suggestive marks that imply an interior setting, perhaps a domestic space, with hints of patterned upholstery or wall coverings. The palette is balanced, relying on the interplay between cool shadows and warmer skin tones.

Van Rysselberghe was a founding member of Les XX, a group that brought together avant-garde artists in Brussels. His work often bridged the gap between the structured approach of Georges Seurat and the more expressive, painterly traditions of the late nineteenth century. In this portrait, the artist captures the character of the sitter through a combination of precise observation and a confident, gestural technique. The surface of the canvas retains a sense of immediacy, as the individual strokes remain visible to the viewer. This piece offers a clear example of the artist's ability to balance formal portraiture with the experimental spirit of his time.
