Portrait of Catalina de la Cerda

The Portrait of Catalina de la Cerda, painted in 1602 and held at the Museo Fundación Lerma, depicts a noblewoman whose identity connects her directly to the most powerful political network of Philip III's reign. The Cerda family was related to the ducal house of Medinaceli, one of the great Castilian noble dynasties, and the Lerma connection embedded in the museum's title points toward the circle of Francisco de Sandoval, Duke of Lerma, Philip III's all-powerful favourite. Court portraiture in this period was not only royal — the great aristocratic families who clustered around the monarchy also commissioned official portraits, and Pantoja's services extended to this elite. Painting a noblewoman required the same skills as painting a queen: precision in costume, dignity in bearing, and a face that combined individual presence with aristocratic ideality. This portrait is a comparatively rare document of Pantoja's non-royal aristocratic commissions.

The painting demonstrates that Pantoja applied consistent standards across royal and aristocratic commissions: the textile rendering, the face modelling, and the dark background treatment are indistinguishable in quality from his royal portraits. The sitter's dress, while elaborately embroidered, lacks the extraordinary jewel inventory of a queen's portrait, reflecting the social hierarchy even within the elite. The handling of the face shows Pantoja's characteristic smooth, layered approach.
