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.
Theodoli Chapel (Santa Maria del Popolo)
The completion of the Theodoli Chapel could be placed around 1575 because Mazzoni returned to Piacenza in the next year. The chapel was refurbished by Marquis Girolamo Theodoli about 150 years later. The large stucco cartouche above the entrance arch with the coat of arms of the Theodoli family probably belongs to this phase. The paintings were restored and refreshed by Giacomo Triga, the court painter of marquis. The 18th century redecoration is probably related to the Jubilee Year of 1725 but the intervention did not significantly alter the 16th century aspect of the chapel.
