“Frick Perspectives: The Glint of Gold: Early Italian Pictures,” by Nathaniel Silver, Isabella Stewart Gardner Museum

• Art/Photo

This lecture explores the collection’s “primitives”—works by Italian Renaissance masters Duccio and Piero della Francesca—and their acquisition by a collector whose taste was formed by her European travels following her father’s death, in 1919.
