Equestrian Portrait of the Duke of Lerma

Felipe III's favorite, Francisco de Sandoval y Rojas, Marquis of Denia and First Duke of Lerma is shown as chief of the Spanish Armies. Wearing half armor, he rides a white steed and carries a ruler's staff. The scallop of the Knights of Saint James at his neck is the only decorative element in this portrait, whose decidedly military orientation is reinforced by the cavalry battle in the background.
