Giuseppe Passeri was an Italian painter and draughtsman, the nephew of the biographer and painter Giovanni Battista Passeri, with whom he trained. He later became the favourite pupil of Carlo Maratta. He painted frescoes and altarpieces for churches and leading Roman families such as the Barberini, Corsini and Pallavicini. In 1700, Pope Clement IX appointed him painter to the Camera Apostolica (a department of the papal court). Little of his work survives outside Rome, although he apparently sent paintings to other Italian cities and to England and Scotland. His most famous work is probably the decoration of the presbytery of Viterbo cathedral (c.1690). He also produced many drawings and designs for engravings including a series of portraits of cardinals for Mario Guarnacci's Vitae et res gestae pontificum romanorum (The lives and deeds of Roman popes), published in 1750. The Royal Collection contains a number of drawings by Passeri.

This miniature is one of the collection of copies of 224 self-portraits by artists in the Uffizi Palace, Florence, that Lord Cowper, the art collector and patron, commissioned Giuseppe Macpherson (1726-1780) to paint. He presented the miniatures to King George III in two batches, in 1773 and 1786. Macpherson followed the original self-portraits quite closely, but copied only the head and shoulders. He inscribed the artists' names on the backs of the miniatures – several differ from those in the modern Uffizi catalogue, notably: Bazzi, Bellini, Campi, Annibale Carracci, Gabbiani, Masaccio, Metsys, Moroni, Pencz, Licinio, Schiavone and Spada. None of the miniatures is signed, apart from Macpherson's own self-portrait, which is inscribed: Giuseppe Macpherson / Autore della serie (Giuseppe Macpherson / Author of the series).Macpherson was born in Florence, the son of Donald Macpherson, a footman in the service of Alexander, 2nd Duke of Gordon. He was a pupil of Pompeo Batoni and painted miniatures and enamel portraits in Italy, France and Germany, finally settling in Florence. A James Macpherson is recorded in London and Paris in 1754 but it is not certain that this is the same person. He was described in 1776 as having a special talent for painting on enamel and as being 'almost the only painter in Europe who possesses this art to perfection'. He had a distinguished client list which included some of the crowned heads and dignitaries of Europe. In 1778, he was invited to add his own self-portrait to the famous painters in the grand duke's collection as it 'would do honour to Florence to enrich the collection with a work which shows that we still have some men of true merit' according to Giuseppe Pelli, director of the Uffizi at the time.
