Housed in the adjacent building, formerly a convent associated with the church, is the Faculty of Engineering ofLa Sapienza University. Confusingly, this academic institution also carries the epithet "San Pietro in Vincoli".
Also known as theBasilica Eudoxiana (Italian:Basilica Eudossiana, it was first rebuilt on older foundations[3] in 432–440 to house therelic of the chains that boundSaint Peter when he was imprisoned inJerusalem, the episode called "Liberation of Saint Peter". The EmpressEudoxia (wife of EmperorValentinian III), who received them as a gift from her mother,Aelia Eudocia, presented the chains toPope Leo I. It was probably during a pilgrimage in 438-439 that Aelia Eudocia had received the chains as a gift fromJuvenal, bishop of Jerusalem.
The chain is now kept in areliquary under the main altar in the basilica.[4] Since 1894, a link of the chain has been housed inSt Peter's Church,[5]Rutland, Vermont.[6] Around the world, numerous churches to St Peter bear theAd Vincula suffix, relating to the basilica and relic.
Of interest in this context are St Peter'stwo imprisonments. According to legend, when Leo compared the Jerusalem chain to that of St Peter's final imprisonment in theMamertine Prison, in Rome, the two chains miraculously fused together.
The basilica, consecrated in 439 bySixtus III, has undergone several reconstructions, among them a restoration byPope Adrian I, and further work in the eleventh century. From 1471 to 1503, when he was electedPope Julius II, Cardinal Della Rovere, the nephew ofPope Sixtus IV, achieved notable rebuilding. The frontportico, attributed toBaccio Pontelli, was added in 1475. Thecloister (1493–1503) has been attributed toGiuliano da Sangallo. The vault was lowered in 1705 under the architectFrancesco Fontana, and there was another renovation in 1875.
The interior has anave and two aisles, with threeapses divided by antiqueDoric columns. The aisles are surmounted by cross-vaults, while the nave has an 18th-centurycofferedceiling, frescoed in the centre byGiovanni Battista Parodi, portraying theMiracle of the Chains (1706). In this scene, based purely on a fable, Pope Alexander heals the neck goiter of the mythicalSaint Balbina by touching her with the chains that had once bound St Peter.
Michelangelo'sMoses statue
Michelangelo'sMoses (completed in 1515), while originally intended as part of a massive 47-statue, free-standing funeral monument forPope Julius II, became the centerpiece of the Pope's funeral monument and tomb in this, the church ofdella Rovere family. Moses isdepicted with horns, connoting "the radiance of the Lord", due to the similarity in the Hebrew words for "beams of light" and "horns". This kind of iconographic symbolism was common in early sacred art, and for an artist horns are easier to sculpt than rays of light.[citation needed]
In 1876 archeologists discovered the tombs of those once believed to be theseven Maccabean martyrs depicted in 2 Maccabees 7–41.[10] They are remembered each year on 1 August, the same day as the miracle of the fusing of the two chains.
The third altar in the left aisle holds a mosaic ofSaint Sebastian from the seventh century. This mosaic is related to an outbreak of plague inPavia, in northern Italy. The relics of Sebastian were taken there in order to stop a 680 outbreak of plague, since Sebastian was believed to have been born in Lombardy, and an altar was constructed for his relics at a San Pietro in Vincoli in Pavia. As a symbol of the subsequently reinforced relationship between Pavia and Rome, an identical altar to Sebastian was built at the Roman church of the same name, resulting in a parallel cult for the saint in both regions.[11]
^From the end of the fifth century, the term Cardinal applied at Rome to priests appointed for life to the twenty-five or so quasi-parishes, or Romantituli, pertaining to the church of the Bishop of Rome as it was at that time. Were a Cardinal-Priest to be subsequently asked to undertake a vacant diocese, his title would change to Cardinal-Bishop. In matters of administration of goods, discipline, or the service of their titular churches, a cardinal has no power of governance, and he is expected not to intervene in such affairs. He is, however, at liberty to donate his own money to help with projects. For example, this building benefitted substantially from the generosity of Cardinal Della Rovere. Nowadays, theDiocese of Rome contains 334 parishes.
