Monuments in the Basilica of Santa Maria del Popolo
This elaborate Baroque monument set against the third pillar of the south aisle has several peculiarities. It is crowned by the coat-of-arms of Pope Nicholas IV (Girolamo Masci) but this medieval pope was buried in the Basilica of Santa Maria Maggiore. The monument in Santa Maria del Popolo was built for his late descendant, Count Masci-Ferracuti from Ascoli Piceno who was appointed to the Bishop of Vieste by Pope Sixtus V in 1589. He died in Rome in 1613 at the age of 60 years. He was buried with solemn pomp in a marble tomb in the basilica. The tomb was built by her niece, Anastasia Mascia and her husband, Marzio Elefantucci, a nobleman from Bologna. Under the pretense of honouring their uncle they built a monument for the most illustrious member of their family, Pope Nicholas IV whose name is mentioned twice in the funerary inscription.
Santa Maria del Popolo
The chapel was named after Bishop Giovanni Montemirabile (†1479) and it was transformed into the baptistery of the basilica in 1561. The most valuable works of art in the chapel are the aediculae of the baptismal font and the font of the holy oil. These were assembled in 1657 from the 15th-century fragments of a demolished monument which had been created by the Bregno workshop. The tomb of Cardinal Antoniotto Pallavicini on the left wall was made by the same workshop in 1501.
