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
In the middle of the 13th century the church was given to the Order of Saint Augustine which has maintained it ever since. The Augustinians were a new mendicant order established under the guidance of Cardinal Riccardo Annibaldi, probably the most influential member of the Roman Curia at the time. Annibaldi was appointed corrector and provisor of the Tuscan hermits by Pope Innocent IV in December 1243. The cardinal convened a meeting to Santa Maria del Popolo for the delegates of the hermitic communities where they declared their union and the foundation of the new order that the Pope confirmed with the bull "Pia desideria" on 31 March 1244.
