Portrait of the Count-Duke of Olivares (Hermitage)

The Portrait of Count-Duke de Olivares is a painting by Spanish artist Diego Velázquez, finished in 1635. It is housed in the Hermitage Museum of St. Petersburg.

The picture portrays Gaspar de Guzmán, Count-Duke of Olivares, Prime Minister of Spain during the reign of Philip IV. He is portrayed in half bust over a neutral background, the face appearing tired and swollen, markedly aged from the previous, more famous equestrian portrait of Duke de Olivares also by Velázquez. Olivares wears a simple black dress with a white ruff.
