St. Peter's Basilica

← Encyclopedia

St. Peter’s Basilica is the great Renaissance church of Vatican City, built over ground that Christian tradition has held since at least the second century to be the burial place of the apostle Peter. It is among the largest churches in the world and, for the Roman Catholic Church, the most charged of its buildings — not the pope’s cathedral, which is the Lateran, but the symbolic center of the papacy and the focus of its great public rites.

The site has a long history beneath the present structure. By the second century a modest monument stood on the slope of the Vatican hill, in a pagan necropolis, marking the spot venerated as Peter’s grave; in the fourth century the emperor Constantine raised a vast basilica over it, leveling part of the cemetery to do so. That Constantinian church stood for more than a thousand years before it was judged unsound. The building that now occupies the site was begun in 1506 under Julius II and took most of the sixteenth and seventeenth centuries to complete, passing through the hands of Bramante, Raphael, Michelangelo — whose dome defines the skyline of Rome — Maderno, and Bernini, who shaped the encircling colonnade of the square. Twentieth-century excavations beneath the high altar recovered an ancient burial that the Church has identified, with caution, as Peter’s; the identification is held by faith more firmly than it can be settled by archaeology.

The Catholic claim attached to the building is doctrinal as much as architectural. The basilica’s authority rests on the tradition that Peter, named in the gospels as the rock on which the church would be built, died and was buried here, so that the bishops of Rome stand in unbroken succession from him — the foundation of papal primacy. The structure renders that claim in stone: the tomb below, the altar above it, the dome above that.

For the esoteric reception of antiquity, the site’s most telling feature stands outside the church. At the center of the square rises an Egyptian obelisk, quarried in the first millennium BCE and brought to Rome under the early emperors, where it stood in the circus of Nero — by tradition near the place of Peter’s death. Re-erected before the basilica in 1586, it placed a pharaonic monument at the threshold of Latin Christendom’s chief shrine, in the same period that Renaissance scholars were reading the Hermetic texts as ancient Egyptian wisdom. The pairing reads as deliberate, and it remains: a stone cut for an Egyptian sun-cult, recrowned with a cross, fixed at the entrance to the tomb of Peter.
