Francesco Vanni was the most important artist in Siena at the turn of the 17th century and a key figure in Italian Counter-Reformation painting. His works combine dazzling technical virtuosity and brilliant coloring with the naturalistic approach to subject matter made famous by the works of his contemporaries Annibale Carracci and Caravaggio. Vanni created altarpieces for every important church in Siena, and he also received commissions in Rome, most notably from Pope Clement VIII for a monumental altarpiece for the basilica of Saint Peter. The first monographic exhibition on this major artist, Francesco Vanni: Art in Late Renaissance Siena includes over 60 paintings and drawings by Vanni, as well as many prints following his designs.
