Equestrian Portrait of the Duke of Lerma

The Equestrian Portrait of the Duke of Lerma (1603) at the Museo del Prado is one of the most important single commissions of Rubens's Italian period — a portrait that revolutionized the equestrian format by presenting the horse and rider moving directly toward the viewer in a foreshortened perspective that had no precedent in European painting. Previous equestrian portraits, including Titian's Charles V at Mühlberg and the equestrian bronzes of antiquity, showed the rider in profile or at three-quarter view; Rubens's frontal approach created a new format of unprecedented visual power, making the viewer feel the approach of the mounted figure with something of the physical intimidation of an actual cavalry charge. The commission came during Rubens's stay in Spain as an envoy of the Gonzaga duke, and the direct access to the Duke of Lerma — Philip III's all-powerful favorite, the most important man in Spain — was a significant diplomatic and professional opportunity. The Prado's possession of this revolutionary work alongside the fullest collection of Rubens in any single institution makes Madrid the essential location for understanding the development of his portrait style.

The composition presents the duke on a powerful white horse advancing directly toward the viewer, a bold compositional choice that creates an imposing sense of power. Rubens' masterful handling of the horse's anatomy and the duke's armor demonstrate his early command of the equestrian portrait.

This groundbreaking equestrian portrait from 1603 is now in the Prado. It was painted during Rubens's visit to the Spanish court. The canvas has been conserved by the Prado's restoration department. The bold compositional innovation of the horse charging toward the viewer has been preserved. Some areas of the background landscape have darkened.
