Giulio Cesare Procaccini (1574–1625) was an Italian painter and sculptor of the late Mannerist and early Baroque periods. Born in Bologna, he initially trained as a sculptor under his father, Ercole Procaccini the Elder, and worked in Milan, where his family had relocated in 1587. By 1600, he shifted his focus to painting, quickly establishing himself as a prominent artist in Lombardy. Procaccini's style blended the emotional intensity of the Baroque with the elegance and refinement of Mannerism. His religious works, including altarpieces and frescoes, often featured dynamic compositions and vibrant color palettes. Among his notable commissions are the frescoes at the Certosa di Pavia and the altarpiece for Milan's Basilica of Sant'Ambrogio. He was particularly adept at conveying religious emotion, influenced by the Counter-Reformation's focus on devotional imagery. His "Assumption of the Virgin" and "Martyrdom of Saints" are regarded as masterpieces of dramatic expression. Procaccini also created smaller devotional works for private patrons, making him highly sought-after by both the church and aristocracy. Though he died relatively young, Procaccini left a significant legacy, influencing Lombard painting and contributing to the transition from Mannerism to the more theatrical Baroque style.
