 Castellesi was a favourite of Pope Alexander VI , which became a liability during the reign of Pope Julius II . During Julius II 's reign , Castellesi , " although neither requesting nor mentioning the office of protector of England , certainly presented himself to Henry VII as the cardinal responsible for English affairs in the Curia " . In an attempt to secure his status against the intrigues of Silvestro Gigli , Castellesi donated his residence , the Palazzo Giraud Torlonia on the present Via della Conciliazione , to Henry VII . In 1504 , Henry VII named six official members of his embassy , headed by Castellesi , and also including Sir Gilbert Talbot , Richard Beere , Robert Sherborne , Silvestro Gigli , and Edward Scott .
