Monuments in the Basilica of Santa Maria del Popolo
The long time gap is explained by the fact that the cardinal was buried in the Old St. Peter's Basilica together with his uncle and benefactor, Cardinal Antonio Pallavicini Gentili (Antoniotto). In 1596 their bodies were relocated to the cemetery Santa Maria del Popolo where Antoniotto's monument was set up and later transferred to the Montemirabile Chapel. Philipp Zitzlsperger calls this a particularly instructive example of the separation of the body and the tomb which increasingly came to be the norm in Rome from the second half of the 16th century because the location of the cardinal's corpse has not been established but the transferral of the remains was reason enough to the relatives to erect a cenotaph in the church itself.
Santa Maria del Popolo
In the 15th century the friary of Santa Maria del Popolo joined the observant reform movement that tried to restore the original purity of monastic life. The general chapter of the Augustinian observants in May 1449 established five separate congregations for the observant friars in Italy. That of Rome-Perugia was sometimes named after Santa Maria del Popolo although the monastery never had the official position of a mother-house. In 1472 the friary was given over by Pope Sixtus IV to the Lombard Congregation, the most important and populous of all, and it became its Roman headquarter and the seat of its procurator general (ambassador) at the Roman Curia.
