The feast of St Peter’s Chains which we keep today originated as the dedication feast of a Roman basilica on the Esquiline hill, within sight of the Colosseum. We do not know precisely when it was first built, but according to a surviving dedicatory inscription, it was already considered old when Pope Sixtus III restored it in the 430s. Apart from the Vatican basilica, it is the only ancient church of note in Rome dedicated to the Prince of the Apostles, and has custody of one of the city’s most important relics, the two chains by which Peter was held in prison.

As such, it was historically one of the most prestigious cardinalitial titles. In 1467, it was conferred upon the 37th Franciscan minister general, Francesco Maria della Rovere, who continued to hold it after his term expired less than two years later, until his election to the papacy with the name Sixtus IV in 1471. A few months later, in the finest traditional of papal nepotism, he bestowed it upon his nephew Giuliano, who held it for almost 32 years, until he was elected pope in 1503, taking the name Julius II. The building owes much of its current appearance, including its façade, to renovation work done at Giuliano’s behest. (It remained in the della Rovere family continually until 1520; 28 years later, it was given to his 13-year old grand-nephew Giulio, who held it for 22 years.)
Sixtus and Julius were major protagonists of the almost unfathomably chaotic political events that took place in Italy in the later 15th and early 16th centuries, but are certainly best known today as the patrons of some of the finest artists of the later Italian Renaissance. In 1508, Julius commissioned Michelangelo to repaint the ceiling of his uncle’s famous chapel, which had originally been just blue with stars.

He also brought in several other notable artists to decorate a new set of staterooms, among them, Raphael Sanzio, a native of the little town of Urbino, and a distant relative of his chief architect, Donatello Bramante. But when Raphael had painted a single wall, the pope was so impressed with his work that he fired all the others so that the whole project could be given to him. Raphael was therefore working on his first room, the Stanza della Segnatura, at the very same time that Michelangelo was working on the Sistine chapel ceiling; he finished his project, which was much smaller, first, in 1511.

When Michelangelo was about half-way done with the ceiling, Pope Julius prevailed upon him, though much against his will, to offer a sneak preview. In an age in which imitation, that is to say, imitation of the classical past, had become the very definition of art, there was no one who had a sharper eye than Raphael for seeing what was good about another artist’s work, taking it into his own, and improving upon it. In his second room, therefore, he immediately revised his style in imitation of Michelangelo’s, not just improving upon it, but making a challenge to his rival; a challenge which, however, would go unanswered.
In the following description, it must be remembered that the first three paintings in the room are in part the work of assistants, as was normally the case in those days. The piece de resistance, however, The Liberation of St Peter from Prison, is basically all Raphael.
The first painting is the one that has given its name to the room, the Stanza of Heliodorus, the agent of the emperor Antiochus who in II Maccabees 3 is sent to Jerusalem to plunder the temple. On the far left, Pope Julius II is carried into the scene on the sedes gestatoria by Swiss guards. (The company was instituted by Julius in 1506, and this is the oldest picture of them as papal guards.) Next to them is a group of citizens of the holy city, anxiously looking on as the high priest in the middle prays for the safety of the temple, and of the treasures that keep it running, and are used to care for the poor.
Notice the very different style of these two group of figures. The pope and the Swiss guards look like they were painted 20 years earlier, by artists of the generation that trained Raphael. The onlookers, on the other hand, are very much in the style of Michelangelo, both in terms of color scheme and pose. The great Florentine was first and foremost a sculptor, and when he was constrained to paint, he painted his human figures (the only subject he was interested in) as if they were sculptures in the sunlight. The woman in the foreground, and the father and son who have climbed up on the pillar to get a better view, are very similar to many of the artfully posed figures in Michelangelo’s ceiling.
