Ottavio Leoni was renowned for his portraits, which he drew from life in colored chalk and later engraved. His advanced command of engraving and his use of stippling are evident in this print of the artist Giovanni Baglione, who decades earlier had implicated Leoni in a libel suit waged against Caravaggio. Baglione’s painting The Ecstasy of Saint Francis of Assisi of 1601 is also in the Art Institute collection (2002.378).
