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
What is certain that the journey was connected to a feud between the Observant and the Conventual monasteries of the Augustinian Order in the Holy Roman Empire and their proposed union. According to the traditional dating Luther arrived in Rome between 25 December 1510 and January 1511. His biographer, Heinrich Böhmer assumed that the young observant friar stayed in the monastery of Santa Maria del Popolo. This assumption was disputed by newer biographers who argued that the tense relationship between the Lombardian Congregation and the administration of the Augustinian order made the monastery of Santa Maria del Popolo an unsuitable lodging for Luther who tried to win a favour at the leaders of his order. Be that as it may, Luther, who spent four weeks in Rome, certainly visited the only observant Augustinian monastery in the city and its famous pilgrimage church that was the favourite of the reigning pope.
