San Silvestro in Capite
Pope Alexander VIII elevated him to the cardinalate in 1690 despite his protests and made him the Cardinal-Deacon of Santa Maria in Aquiro but he later opted for the "Diaconia" of San Adriano al Forno and later, as the Cardinal-Priest, for the "titulus" of San Silvestro in Capite. He was then ordained to the priesthood in September 1700 and celebrated his first Mass in Rome on 6 October 1700.
