In Three Soldiers, One Seated on a Square Block of Stone, we see three soldiers depicted in a rugged landscape. The colors are earthy, with browns and greens dominating the scene. One soldier is seated on a large stone block, while the others stand nearby, creating a sense of camaraderie.

The figures are robust and muscular, typical of the Baroque style. The painting is executed in oil on canvas, a common medium for the Baroque period. The dimensions are approximately 100 x 130 cm, giving it a substantial presence. The use of light and shadow enhances the three-dimensionality of the figures, a hallmark of Salvator Rosa's technique.

The composition draws the viewer's eye to the seated soldier, emphasizing his role in the narrative. Salvator Rosa was known for his dramatic landscapes and historical scenes, often infused with a sense of adventure. This work reflects his interest in military themes and the human condition. An interesting fact about this painting is that it showcases Rosa's ability to blend realism with a dramatic flair, making it a notable piece in his oeuvre.

It is currently housed in the Museo del Prado in Spain.
