In Soldier Holding a Long Sword with Both Hands, the central figure is a soldier gripping a long sword firmly. He is depicted in a dynamic pose, suggesting readiness for battle. The colors are rich and dark, typical of the Baroque style, with deep reds and browns dominating the palette.

The background is somewhat muted, allowing the soldier to stand out as the focal point of the composition. The painting is executed in oil on canvas, a common medium during the Baroque period. The dimensions are approximately 100 x 150 cm, giving it a substantial presence. The brushwork is detailed, particularly in the rendering of the soldier's armor and facial features.

This attention to detail enhances the realism and intensity of the figure. Salvator Rosa was known for his dramatic and often theatrical compositions, reflecting the turbulent times of the 17th century. This work, likely created in the 1660s, showcases his interest in military subjects and the heroic ideal. An interesting fact about this painting is that it reflects Rosa's own experiences as a soldier, which influenced his artistic perspective.

His works often blend realism with a sense of the dramatic, making them stand out in the Baroque movement.
