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.
Gian Lorenzo Bernini
Bernini was also a leading figure in the emergence of Roman Baroque architecture along with his contemporaries, the architect Francesco Borromini and the painter and architect Pietro da Cortona. Early in their careers they had all worked at the same time at the Palazzo Barberini, initially under Carlo Maderno and, following his death, under Bernini. Later on, however, they were in competition for commissions, and fierce rivalries developed, particularly between Bernini and Borromini. Despite the arguably greater architectural inventiveness of Borromini and Cortona, Bernini's artistic pre-eminence, particularly during the reigns of popes Urban VIII (1623–44) and Alexander VII (1655–65), meant he was able to secure the most important commissions in the Rome of his day, the various massive embellishment projects of the newly finished St. Peter's Basilica, completed under Pope Paul V with the addition of Maderno's nave and facade and finally re-consecrated by Pope Urban VIII on 18 November 1626, after 150 years of planning and building. Bernini's design of the Piazza San Pietro in front of the Basilica is one of his most innovative and successful architectural designs. Within the basilica he is also responsible for the Baldacchino, the decoration of the four piers under the cupola, the Cathedra Petri or Chair of St. Peter in the apse, the chapel of the Blessed Sacrament in the right nave, and the decoration (floor, walls and arches) of the new nave.
