A young man with long, curling blond hair sits in a richly upholstered chair, his body turned slightly to the left while his face meets the viewer directly. He wears a voluminous white shirt with a high collar and a gleaming, deep red cloak that drapes across his lap and arm, catching the light in broad, fluid folds. A slender greyhound stands at his side, its head raised and muzzle almost touching the sitter’s hand, which rests gently on the dog’s neck.

Behind the figure, a heavy curtain patterned with large, golden leaves sweeps diagonally across the background, its dark shadows contrasting with the luminous fabrics in the foreground. To the right, a tall pike leans against the chair, its polished metal head catching a glint of light, while the shaft disappears behind the sitter’s arm. The sitter’s expression is composed and reserved, his gaze steady and lips closed, suggesting a sense of calm authority.

The background opens to a distant, green landscape under a cloudy sky, glimpsed through a gap in the curtain at the far left edge. The artist uses smooth, blended brushwork for the sitter’s face and hands, while looser, broader strokes describe the folds of the red cloak and the patterned curtain. The palette contrasts the cool whites and pale flesh tones of the sitter with the warm reds and golds of the textiles, and the muted greens and blues of the landscape beyond.

Small details, such as the gold studs on the chair and the delicate chain around the greyhound’s neck, are rendered with careful precision. Anthony van Dyck paints this portrait in 1636, depicting James Stuart (1612–1655), 1st Duke of Richmond and 4th Duke of Lennox, as identified in the title and museum records. This work is part of the Iveagh Bequest at Kenwood House, where it has been held since 1929. The subject’s identity as James Stuart, 1st Duke of Richmond and 4th Duke of Lennox, is confirmed by the title and museum documentation.

Anthony van Dyck is the creator, as noted in the museum’s entry and the artwork’s title.
