Adrian died a few months later and was succeeded on 19 November 1523 by Giulio di Giuliano de' Medici as Clement VII. Giulio was Rucellai's illegitimate cousin, and soon appointed him Castellano of Castel Sant'Angelo. A book in dialogue form by Gian Giorgio Trissino on the Italian language is called "Il Castellano"; it records the discussions of Trissino, Rucellai and other friends in the small garden of Castel Sant'Angelo, with its bitter orange trees.
