Simone Martini and Lippo Memmi ~ Biography
Simone Martini (1284 – 1344), was a major figure in the development of early Italian painting and greatly influenced the development of the International Gothic style. It is thought that Martini was a pupil of Duccio di Buoninsegna (1255 – 1260), the leading Sienese painter of his time. Very little documentation survives regarding Simone's life, and many attributions are debated by art historians.
His brother-in-law was the artist Lippo Memmi (1291 – 1356), who is noted as the foremost follower of Martini’s work. Together, between 1329 and 1333 they executed one of the masterworks of International Gothic painting, the Annunciation Altarpiece for the Sienese church of Sant'Ansano in Siena, now in the Uffizi. It is said that Memmi painted the two Saints, Ansano (Patron Saint of Siena) and Giulitta, while Martini painted the Virgin and the Angel Gabriel. (Kren and Marx, Web Gallery of Art)
