Santa Maria Maggiore stands on Rome’s Esquiline Hill and is one of the city’s four papal basilicas. Inside Santa Maria Maggiore, the nave’s long colonnade draws the eye toward a sequence of mosaics whose different dates are central to understanding the building.
The mosaics in the nave and triumphal arch date to the pontificate of Sixtus III (432–440). On the nave walls, one side follows Abraham and Jacob, while the other follows Moses and Joshua; the triumphal arch’s largely preserved cycle tells the story of Christ’s childhood. The apse belongs to a later moment: Pope Nicholas IV commissioned its mosaics from Jacopo Torriti. Their subjects and dates give the nave, arch and apse different roles in the interior.
The floor and ceiling extend that layered view in different directions: the central nave has a Cosmatesque pavement and a gilded timber coffered ceiling designed by Giuliano and Antonio da Sangallo. The church remains an active place of devotion. The Salus Populi Romani is kept in the Pauline Chapel; its traditional attribution to Saint Luke is devotional tradition, not established authorship. In 1954, the icon was carried in procession from here to St Peter’s Basilica for its coronation. Pope Francis’s tomb is in the left aisle between the Pauline and Sforza Chapels.
Two objects associated with the Nativity also have separate settings. Five pieces of sycamore wood venerated as the Holy Crib are kept in the Confessio before the Papal Altar. Arnolfo di Cambio’s marble Nativity, commissioned in 1291, is presented in the Liberian Museum. The traditional account that an August snowfall revealed the basilica’s site is recalled each year with falling white petals, keeping the story visible as tradition.
