The church itself claims to be the first Roman church dedicated to the Mother of God -- though some would give that honour to Santa Maria Maggiore. As mentioned, the present church building dates substantially from the twelfth century, raised n the foundations of the fourth century church.
The facade of the basilica presents us with a combination of a twelfth century belltower and mosaic decoration, while the neo-classical portico comes from 1702 -- replacing the original medieval one. The portico has a beautiful collection of classical era monuments -- mainly inscriptions -- which have been embedded into the walls.
The facade's decoration includes a scene of the Virgin Mary nursing the Christ child, with ten female saints flanking her, holding lamps. Beneath these, found adjacent to the windows, are depicted palm trees. The portico itself is decorated with four statues depicting four saints: Ss. Callixtus (+222), Cornelius (+253), Julius (+352) and Calepodius (+232).
But if the exterior with its fountain and piazza and facade are beautiful to behold, the interior is all the more spectacular, lined as it is by twenty two granite columns taken as spoila from the Roman baths of Caracalla.
"Fons olei" can be seen on the transenna shown here, which refers to an early Roman Christian legend about a spring of oil that purportedly appeared here proximate to the birth of Christ |
The main altar includes a beautiful ciborium magnum which actually dates from the nineteenth century but integrates so harmoniously into the building one would never know it. The present incumbents of S. Maria in Trastevere have adopted the rather unfortunate modern Italian practice of placing two (rather disproportionate) candlesticks to one side and the altar cross on the other, not to mention a Russian style icon of the Holy Face (beautiful insofar as it goes, but not particularly in harmony with either the altar nor the rest of the building). For some comparison, I have dug up some antique images showing how the altar was found before the later part of the twentieth century.
