The Sienese School refers to a group of artists and a distinctive style of painting that emerged in Siena, Italy, during the late Middle Ages, particularly in the 13th and 14th centuries. This school is known for its elegant and decorative approach, often characterized by intricate details, vibrant colors, and a focus on religious themes. Artists like Duccio di Buoninsegna and Simone Martini were prominent figures in this movement, contributing to its unique aesthetic. The Sienese style contrasts with the more naturalistic approach of the Florentine School, which was developing simultaneously in Florence. While the Florentine artists emphasized perspective and human anatomy, the Sienese favored a more stylized and ornamental representation. This distinction helped shape the evolution of Italian art during the Renaissance, influencing later artists and movements.
