He was nominated as one of the English prelates for the Lateran council (1512), but did not attend.
He permitted laymen to hold certain public offices, under surveillance of the prelates, organized a guard from among the Roman nobility, decreed a plan for redeeming the base coinage, permitted the communes a certain degree of municipal liberty, and promised the liquidation of the public debt.
This question was solemnly submitted to a grand council of prelates, senators, ministers and other dignitaries on the 13th of June 1718.
He reformed the administration and extended the powers of the Sicilian parliament, which was composed of the barons, the prelates and the representatives of the towns.
But he was a patron of learning and, like most prelates of his age, a great architect.
