A man stands at three-quarter length, his right hand resting lightly on a stone ledge and his left hand relaxed by his side. He wears a black doublet with a broad white collar and voluminous white sleeves that billow from beneath the dark fabric. A vivid red sash is tied at his waist, its color striking against the otherwise somber palette of black and white.

His long, wavy hair frames a composed face, and a neatly trimmed mustache and small beard accentuate his features. The sitter gazes directly outward, his expression calm and self-assured, with a slight flush to his cheeks. A heavy black cloak is draped over his left arm, its folds rendered with smooth, fluid brushwork that catches the light.

The background is a muted brown, softly modeled, with a subtle architectural element—a corner of a wall or column—behind his right shoulder. Light falls from the left, illuminating his face, collar, and hands, while casting gentle shadows that enhance the sense of depth and volume. The paint surface is smooth and refined, with delicate transitions in the modeling of flesh and fabric, and precise attention to the textures of skin, linen, and silk.

The composition is balanced and dignified, with the figure slightly off-center and the ledge anchoring the lower right corner. Small details, such as the subtle creases in the white sleeves and the translucency of the red sash, reveal the artist’s careful observation. The work is a portrait, depicting Pomponne II de Bellièvre, as identified in the title and supporting records. The painting dates from between 1638 and 1639, according to the Seattle Art Museum and other sources.
