San Pietro in Montorio

San Pietro in Montorio is a church in Rome, Italy, which includes in its courtyard the "Tempietto", a small commemorative "martyrium" (tomb) built by Donato Bramante.
History.
The Church of San Pietro in Montorio was built on the site of an earlier 9th-century church dedicated to Saint Peter on Rome's Janiculum hill. It serves as a shrine, marking the supposed site of St. Peter's crucifixion.
In the 15th century, the ruins were given to the Amadist friars, a reform branch of the Franciscans, founded by the Blessed Amadeus of Portugal, who served as confessor to Pope Sixtus IV from 1472. Commissioned by Ferdinand and Isabella of Spain.
It is a titular church, whose current title holder, since 1 March 2008, is Cardinal James Francis Stafford.
Interior.
The church is decorated with artworks by prominent 16th- and 17th-century masters.
The first chapel on the right contains Sebastiano del Piombo's "Flagellation" and "Transfiguration" (1516–24). Michelangelo, who had befriended Sebastiano in Rome, supplied figure drawings that were incorporated into the "Flagellation".
The second chapel has a fresco by Niccolò Circignani (1554), some Renaissance frescoes from the school of Pinturicchio, and an allegorical sibyl and virtue attributed to Baldassarre Peruzzi.
The fourth chapel has a ceiling fresco by Giorgio Vasari. Although there is no grave marker, tradition has it that Beatrice Cenci—executed in 1599 for the murder of her abusive father and made famous by Percy Bysshe Shelley, among others—is buried either in this chapel or below the high altar.
The ceiling of the fifth chapel contains another fresco, the "Conversion of St. Paul", by Vasari. The altarpiece is attributed to Giulio Mazzoni, while the funerary monument of Pope Julius III (Giovanni Maria Del Monte) and Roberto Nobili are by Bartolomeo Ammannati. Also buried in the chapel is Julius III's scandalous 'nephew', and probable lover Cardinal Innocenzo Ciocchi Del Monte.
Until 1797, Raphael's final masterpiece, the "Transfiguration" graced the high altar; it is now in the Vatican pinacoteca. The altar currently displays a copy by Cammuccini of Guido Reni's "Crucifixion of St. Peter" (also now in Vatican museum).
The last chapel on the left contains a "Baptism of Christ", attributed to Daniele da Volterra, and stucco-work and ceiling frescoes by Giulio Mazzoni.
A pupil of Antoniazzo Romano frescoed the third chapel with the "Saint Anne, Virgin, and Child".
Dirck van Baburen, a central figure of the Dutch Caravaggisti, painted the "" for the Pietà Chapel, which is indebted to Caravaggio's example. Baburen worked with another Dutch artist, David de Haen in this chapel. The two other paintings, "The Mocking of Christ" and "The Agony in the Garden" are variously attributed to either or both of the artists.
The second chapel on the left, the Raimondi Chapel (1640), was designed by Gian Lorenzo Bernini. It includes Francesco Baratta's "Saint Francis in Ecstasy" and sculptures by Andrea Bolgi and Niccolò Sale.
Irish chieftains' tombs.
At the high altar are two tombs: that of Hugh O'Neill, The O'Neill, 2nd Earl of Tyrone and his son Hugh who predeceased him, and the tomb shared by Rory O'Donnell, 1st Earl of Tyrconnell, and his brother Cathbharr, both of them younger brothers of Red Hugh O'Donnell.
These fled Ireland in 1607. Rory, Lord Tyrconnell, died in 1608, his brother Cathbharr ("Calfurnius" in the inscription) and Hugh, the son of the Great Earl, died in 1609. The cause of death in all cases was fever, probably malaria. Their tombs are covered with marble inscribed slabs with coloured borders, crests and shields. They are about 12 feet from the altar on the left as you face it and are normally covered by a carpet.
Lord Tyrone himself died in 1616 and was buried in the church with much less solemnity. The original simple tombstone was lost in about 1849, but the text of the short inscription was copied: "D.O.M. Hugonis principis ONelli ossa" (Dedicated to God the Best and Greatest. The bones of Prince Hugh O'Neill). In 1989, Tomás Cardinal Ó Fiaich laid a new marble plaque with the same inscription in approximately the original place.
The "Tempietto".
The so-called "Tempietto" (Italian: 'small temple') is a small commemorative tomb ("martyrium") designed by Donato Bramante, possibly built as early as 1502 in the courtyard of San Pietro in Montorio. Commissioned by Ferdinand and Isabella, the Tempietto is considered a masterpiece of High Renaissance Italian architecture.
After spending his first years in Milan, Bramante moved to Rome, where he was recognized by Cardinal Giuliano della Rovere, the soon-to-be Pope Julius II. In Rome, Bramante was able to study the ancient monuments firsthand. The temple of Vesta at Tivoli was one of the precedents behind the Tempietto. Other antique precedents Bramante was able to study in Rome include the circular temple of the banks of the Tiber, Temple of Hercules Victor, believed at the time to be a temple of Vesta. However, circular churches had already been employed by early Christians for martyriums, like Santa Constanza, also in Rome. Bramante would have been aware of these early Christian precedents, and as a result, the Tempietto is circular.
The "Tempietto" is one of the most harmonious buildings of the Renaissance. The temple was constructed from bearing masonry. The circular temple supports a classical entablature, and was framed in the shadowy arch of the cloister. It is the earliest example of the Tuscan order in the Renaissance. The Tuscan is a form of the Doric order, well suited for strong male gods (such as Hercules) so Tuscan was well suited for St. Peter's. It is meant to mark the traditional exact spot of St. Peter's martyrdom, and is an important precursor to Bramante's rebuilding of St. Peter's.
Given all the transformations of Renaissance and Baroque Rome that were to follow, it is hard now to sense the impact this building had at the beginning of the 16th century. It is almost a piece of sculpture, for it has little architectonic use. The building greatly reflected Brunelleschi's style. Perfectly proportioned, it is composed of slender Tuscan columns, a Doric entablature modeled after the ancient Theater of Marcellus, and a dome. Bramante planned to surround the building with concentric rings of colonnades, the columns of which would have been radially aligned to those of the "Tempietto", but this plan was never executed.
