**Raffaello Schiaminossi (1572–1622)** was an Italian engraver and painter of the late-Mannerist and early-Baroque periods, active primarily in Tuscany. Born and died in Sansepolcro (also known as Borgo San Sepolcro), he specialized in detailed etchings and engravings, often reproducing or interpreting works by leading artists of his time.
Schiaminossi produced engravings after masters such as Cornelis Cort, Federico Barocci, and Ventura Salimbeni. The latter supplied designs for one of his most notable projects, the series *Quindecim Mysteria Rosarii Beatæ Mariæ Virginis* (“The Fifteen Mysteries of the Rosary”), a substantial collection of devotional prints. He also created the *Twelve Caesars* series in 1606, whose copperplates were later reused in unexpected ways, including as supports for paintings. Many of his prints were published by the Sienese print dealer and publisher Matteo Florimi, with whom he collaborated on religious and allegorical subjects around 1606–1607.
Working in the transitional style between Mannerism and the emerging Baroque, Schiaminossi excelled at intricate line work and expressive figure compositions suited to both sacred and secular themes. His output included etchings of prophets, sibyls, and combat scenes, reflecting the period’s interest in classical antiquity and Counter-Reformation piety. Though biographical details of his training remain limited, his technical skill and choice of models demonstrate close engagement with the leading printmakers and painters of central Italy.
Schiaminossi’s legacy endures through his prints preserved in major collections, including the Metropolitan Museum of Art and the National Gallery of Art. His work contributed to the dissemination of Mannerist and early Baroque imagery across Europe via the flourishing print trade of the early seventeenth century.
