  • Summary

    The shock occasioned by the Arab sack of Saint Peter’s and San Paolo fuori le mura in August 846 serves as the backdrop for the unprecedented building activities of Pope Leo IV (847–855), best known for his construction of fortifications to enclose the entire area around Saint Peter’s in what subsequently came to be known as the ‘Leonine city’. This was the only extension ever made to Rome’s Aurelian walls of the late third century. Considerable resources were also expended on making good the losses of gold and silver liturgical vessels, silk textiles and other furnishings. New church projects included Santi Quattro Coronati and Santa Maria Nova. Also dating from his reign, and signalling a shift in patronage to become more evident in the years to follow, is a subsidiary chapel in the excavated lower church of San Clemente, which includes the pope’s portrait. Consideration is given to the rationale for the installation of this chapel, possibly with a relic from the site of Christ’s Ascension prominently displayed above its altar.
