Cosimo III de' Medici, Grand Duke of Tuscany
In 1691, he moved to Rome, where he was patronized by Cosimo III de' Medici, Grand Duke of Tuscany, an enthusiast of Luti's pastel portraiture. Luti was one of the first artists to work in pastels as the final composition as opposed to initial studies for paintings or frescoes. He also worked in oils and painted frescoes, including for the Basilica di San Giovanni in Laterano.
