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.
Cybo-Soderini Chapel (Santa Maria del Popolo)
There is not much left of the original Renaissance interior of the chapel except the large crucifix on the altar and the slabs of the beautiful marble transenna. It is uncertain whether it had any painted decoration. The chapel was fully restored after 1636 in Baroque style by a certain Innocenzo Cybo (†1640). At the time the walls and the vault were decorated with the extant frescos of Pieter van Lint, Ionic stucco capitals were added to the half-columns of the entrance arch and the burial vault was sealed with a new tomb slab.
