CAGNOLA, LUIGI, MARCHESE (1762-1833), Italian archi tect, was born on June g, 1762, in Milan, and died on Aug. 14, 1833, at Inverigo. He was sent at the age of 14 to the Clementine college at Rome, and afterwards studied law at Pavia. He spent two years in Verona and Venice, studying the architectural struc tures of these cities. In 18o6 he was called upon to erect a tri umphal arch at Milan for the marriage of Eugene Beauharnais with the princess of Bavaria. The arch was of wood, but was of such beauty that it was resolved to carry it out in marble. The result was the magnificent Arco della Pace in Milan, surpassed in dimensions only by the Arc de Triomphe in Paris. Among Cagnola's principal works are the Porta di Marengo at Milan, the campanile at Urgnano, and the chapel of Santa Marcellina in Milan.
