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
Julius II granted assent to the wealthy Sienese banker, Agostino Chigi, who was adopted into the Della Rovere family, to build a mausoleum replacing the second side chapel on the left in 1507. The chapel was dedicated to the Virgin of Loreto whose cult was ardently promoted by the Della Rovere popes. The Chigi Chapel was designed by Raphael and it was partially completed in 1516 but remained unfinished for a very long time. This ambitious project created a strong connection between the basilica and the Chigis that extended well into the next century.
