A winged female figure leans forward from the left, her body twisting as she places a laurel wreath onto the head of a muscular, bearded man seated at the center. He clutches a staff in his right hand and a shield in his left, his gaze turned upward in a moment of tense anticipation. Behind him, a putto hovers, holding a burning torch that casts a glow across the upper part of the scene.

A large heap of gleaming armor and weaponry dominates the right half of the composition, with breastplates, helmets, swords, and shields piled in chaotic abundance. A white standard rises diagonally from the mass of arms, its fabric catching the light against a dark, turbulent background. In the foreground, a drum sits at the man's feet, and scattered firearms, swords, and a helmet are strewn across the ground, rendered with meticulous attention to metallic shine and surface detail.

The figures are modeled with energetic, swirling brushwork, especially in the drapery and hair, while the metallic objects are painted with crisp, reflective highlights that contrast with the softer flesh tones. The composition is arranged in a sweeping diagonal from lower left to upper right, guiding the viewer from the dynamic gesture of the winged figure to the luminous pile of armor and the unfurled flag. The dramatic lighting emphasizes the central action, casting deep shadows and intensifying the sense of movement and triumph.

Small details, such as the intricate fastenings on the armor and the delicate feathers of the winged figure, reveal the artist's command of texture and form. Der Sieg (Mars von einer Viktorie gekrönt) is attributed to Peter Paul Rubens, whose career spanned from 1577 to 1640. The painting falls within the period between 1577 and 1640, as indicated by the collection's record.
