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.
Tiberio Crispo
As papal legate to Perugia, Crispo was a "driving force behind the architectural renewal of the city". For example, in 1547 Crispo commissioned Galeazzo Alessi for the construction of Santa Maria del Popolo to replace a church demolished by the construction of the Via Nuova. He also commissioned a palace in Bolsena that bears his name, "Palazzo di Tiberio Crispo" (also known as the "Palazzo Crispo Marsciano" or "Palazzo Rondanini alla Rotonda"), which was designed by Antonio da Sangallo the Younger circa 1543; after the death of Sangallo in 1546, Raffaello da Montelupo was called in to finish the palace, which remained incomplete, however, after the deaths of both Crispo and Raffaello in 1566.
