Sienese painting refers to the artistic style that developed in the city of Siena, Italy, particularly during the late Middle Ages and the early Renaissance. Characterized by its vibrant colors, intricate details, and decorative patterns, this style often emphasized religious themes and narratives. Notable artists from this tradition include Duccio di Buoninsegna and Simone Martini, who contributed significantly to the development of Sienese art. The Sienese school is known for its use of gold leaf and elaborate backgrounds, creating a sense of depth and richness. The paintings often feature elongated figures and expressive faces, conveying emotion and spirituality. This unique approach set Sienese painting apart from other regional styles, such as Florentine painting.
