Simone Martini (1284—1344) was an Italian painter born in Siena. He 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, the leading Sienese painter of his time.
