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
The basilica almost reached its final form with the Berninian reconstruction. The last important addition happened during the pontificate of Innocent XI. His Secretary of State, Cardinal Alderano Cybo demolished the old family chapel (the second on the right) and built the sumptuous Baroque Cybo Chapel on its place that was designed by Carlo Fontana between 1682 and 1687. The large domed chapel was decorated with paintings by Carlo Maratta, Daniel Seiter and Luigi Garzi. It is regarded one of the most significant sacral monuments erected in Rome in the last quarter of the 17th century.
