(1702–86). Italian architect and decorator, he is best known for his work at the Villa Albani (now Torlonia), Rome (from 1746), including the casino, coffee-house, temples, and fountains, which demonstrate his mastery of scenographic effects. While the casino's arcaded front owes much to Michelangelo's Palazzo dei Conservatori, Rome, the temples show the influence of Winckelmann's Neo-Classicism, especially the Tempietto Diruto (1751–67), an artificial ruin composed of Antique fragments. He designed the new Sacristy, St Peter's, Rome (1776–83).
