(c. 1539–1615). Italian architect, military engineer, and soldier. In 1584 he was called to Turin to serve as architect and engineer to Carlo Emanuele I, Duke of Savoy (reigned 1580–1630). He designed the Churches of Santa Maria del Monte (or dei Cappuccini) (1585–96), Santissima Trinità (begun 1598), and Corpus Domini (1607), in Turin. Santissima Trinità has a plan based on a star within a hexagon, pre-empting Borromini's later Church of Sant'Ivo in Rome (1643–60). His greatest work was the huge centrally planned domed Santuario di Vico, Mondovì, Piedmont (also called Vicoforte di Mondovì—1596–1736), based on an ellipse and anticipating C17 Baroque plans. He made a contribution to the urban design of Turin, including the façades of the Piazza Castello (1606) and the adjoining Contrada Nova (1615), both of which served as models for subsequent developments in the city. He fortified the town of Cherasco from 1610, and wrote a treatise on fortifications (1589).
