A young man stands full-length against a dark, neutral background, his body turned slightly to the right while his face looks directly outward. He wears an elaborate black outfit with a broad, pleated cloak that sweeps over his left arm, richly textured with fine, parallel brushstrokes that catch the light. A large, white lace collar rests on his shoulders, its intricate patterns rendered with delicate, almost feathery strokes.

The sitter's right hand holds a pair of tan gloves, his fingers gently curled around them, while his left arm bends at the elbow, drawing attention to the voluminous sleeve and the shimmer of the fabric. His breeches and doublet are made of the same black, ribbed material, adorned at the waist and knees with elaborate silver lace rosettes and tassels that glint in the light. A wide-brimmed black hat sits atop his light brown, shoulder-length hair, framing a round, youthful face with a faint smile and a steady gaze.

The sitter stands on a pale, tiled floor, the geometric pattern subtly receding into the shadowed background and grounding the figure within the space. The shoes are black with large, ornate silver lace decorations, echoing the embellishments on his clothing and adding to the sense of formality and display. Light falls from the left, illuminating the sitter's face, collar, and the folds of his costume, while the right side recedes into shadow, creating a strong contrast that emphasizes the three-dimensionality of the figure.

The background is a soft, dark gradient, free of detail, which serves to focus all attention on the sitter and his attire. The artist renders textures with remarkable clarity, from the crisp lace and satin sheen to the smoothness of the gloves and the subtle blush of the sitter’s skin. The composition is carefully balanced, with the figure occupying the center of the canvas, his extended right arm and the sweep of the cloak adding a sense of movement and grandeur.

Every detail, from the glint of the shoe buckles to the shadow cast by the hat, is painted with precision and a keen sense of observation. Marten Soolmans is the work of Rembrandt van Rijn, as stated in the title line.
