Studio of Sir Peter Lely, British 1618-1680- Portrait of Elizabeth Willoughby, Countess of Ranelagh (c.1633-1695), seated full-length in a landscape, circa 1660; oil on canvas, 165x118cm Provenance: (Probably) Christie's, London, Henry William Fitzgerald-de Ros, 22nd Baron de Ros, 4 June 1839; Private Collection, England; Christie’s, London, 7th December 1945, lot 113; Hans Roger Madol, London; Private Collection, Luxembourg Note: Sir Peter Lely was arguably the most fashionable portrait painter in his day. It was in this capacity that he depicted many of the key figures of mid-seventeenth-century England, including Charles I, Charles II, and Oliver Cromwell. Lely’s work shows the influence of a number of contemporaries, most notably his predecessor as court painter, Anthony van Dyck. Lely was known for his heavy reliance on his workshop, and many of his works were painted in large part by his studio assistants, with Lely himself painting the sitter’s face, or adding final details to the piece.
