A young man sits quietly beside a stove, his body turned slightly to the right while his gaze meets the viewer directly. He wears a dark, formal coat with a broad white collar and cuffs, the crispness of the linen sharply outlined against the deep shadow of his clothing. A black cap sits atop his head, its edge just visible against the dark background, and his expression is calm, with a faint, almost private smile.

Both hands rest in his lap, fingers loosely interlaced, rendered with broad, creamy brushstrokes that suggest the texture of skin and the subtle tension of repose. Behind him, the stove is only partially visible, its form suggested by a gentle glow and a few horizontal lines that recede into shadow. The background is painted in deep browns and blacks, with only a few hints of structure or furniture, focusing attention on the sitter’s illuminated face and hands.

Rembrandt uses thick, visible brushwork, especially in the highlights of the face and hands, giving the surface a sense of movement and immediacy. The composition is tightly framed, with the figure filling much of the panel, creating an intimate atmosphere. Subtle gradations of shadow and light play across the sitter’s features and clothing, demonstrating a mastery of chiaroscuro. The title identifies the sitter as Jan Boursse and places him beside a stove, a detail that anchors the portrait in a domestic interior.

Portrait of Jan Boursse, Sitting by a Stove is painted by Rembrandt in 1666. The museum collection Am Römerholz and Julius Böhler AG are both associated with the painting’s provenance.
