María Pilar de la Cerda y Marín de Resende, Duchess of Nájera

López Portaña employs a pronounced chiaroscuro, allowing the light to model the duchess’s facial features and the folds of her pink, lace‑trimmed gown against a deep, shadowy backdrop. The painter’s meticulous rendering of textures—silk, lace, feather, and polished wood—demonstrates his command of oil paint to convey material richness and three‑dimensional form.

Since its creation, the portrait has remained within Spanish collections, ultimately entering the holdings of Madrid’s Museo del Prado. The painting’s presence in the national museum reflects its value as a representative example of late eighteenth‑century court portraiture and López Portaña’s role as a leading court painter.
