(1690–1768). Italian painter, born in Rome. He was apprenticed first to Andrea Procaccini (1671–1734) and later to Maratti. With the death of Chiari in 1727 he became the last major figure surviving from the Maratti School and played an important role in perpetuating the style. He enjoyed much patronage from the Rospigliosi family and worked on the decoration of the audience chamber in the Palazzo Rospigliosi-Pallavicini, Rome, where he completed a large canvas of Hercules Received on Olympus. Another influential patron was King João V of Portugal for whom Masucci painted several religious subjects, including three for the chapel of S. John in S. Roch, Lisbon (1747). He was most influential as a portrait painter and painted several of the Rospigliosi family, including Cardinal Banchieri (1728; priv. coll.). However, his reputation suffered a setback after his portrait of Pope Benedict XIV (1743; Rome, Accademia di S. Luca) was compared unfavourably with a portrait of the Pope by Subleyras (1740; Chantilly, Mus. Condé). He was well supported by the British and painted striking portraits of James Ogilvie, Lord Deskford (Cullen House, Banff), and John,4th Earl of Hyndford (Skirling House, Lan.). He also recorded the marriage of James Francis Edward Stuart to Maria Clementina Sobieska (Edinburgh, Scottish NPG). His pupils included Batoni and the Scotsman Gavin Hamilton.
