Portrait of Sir Robert Shirley

The Portrait of Sir Robert Shirley is a painting by Sir Anthony van Dyck, a Flemish Baroque artist. It is a portrait of Sir Robert Shirley (c. 1581 – 13 July 1628), the ambassador to the Safavid Shah Abbas ( r. 1588–1629), beginning in 1608. This painting was completed in Rome in 1622 and is one of a pair; its pendant depicts Shirley's wife, Lady Teresa Sampsonia, a Circassian noblewoman. It is notable for the rich Persian dress worn by Shirley. Both of these paintings are now in the collection of Petworth House, in West Sussex.
