Maratta was a well-known portrait painter. He painted Sacchi (c. 1655, Prado), Cardinal Antonio Barberini (c. 1660 Palazzo Barberini), Pope Clement IX (1669, Vatican Pinacoteca) and a self-portrait (c. 1695, Brussels). He also painted numerous English sitters during their visits to Rome on the Grand Tour, having sketched antiquities for John Evelyn as early as 1645.
