The arresting power and vitality of this portrait are typical of Bernini's achievement with such works. His chiselling is so fine that the marble seems to take on the properties of skin, hair and silk. The slight twist to the head and shoulders and the rippling folds and buttons enhance its lifelike appearance, although it was carved fifteen years after the sitter's death. Bernini made the bust for the archbishop's nephew, Cassiano dal Pozzo, around 1622-4. He was one of the most distinguished and learned figures in the cultural life of Rome. The bust was displayed in a prominent position in his palace.
