Santa Maria in Trastevere

Address: Piazza S. Maria in Trastevere - 00100 Roma RM Italy


This is the first Rome church to be consecrated to the Madonna. Its foundations were laid in approximately 400, when Christianity was only just beginning to take root in Europe.

The present edifice is dated 1300 and contains beautiful mosaics by Pietro Cavallini, especially those dedicated to the life of the Virgin Mary.

There is a magnificent life-size icon, 'La Madonna della Clemenza', from as early as the 7th century. The nave is formed from granite columns taken from ancient Roman edifices.

The 12th-century mosaics of the façade, depicting the Madonna and child and ten women holding lamps, are not to be missed.

The portico was renovated in the 18th century by Carlo Fontana and the balustrade is decorated with statues of Popes, baroque additions which do not detract from the church's original medieval aspect.

While Octavian Augustus was consolidating his hold over Rome, not too many years before the birth of Christ, a strange thing happened where this church now stands: oil started to gush from the earth. Some believe this is pure myth, but if so it's old myth, since it is recorded — very much in passing, in just six words — by the early 3c Greek historian Dio (48.43.4) who by placing the event in the consulate of Appius Claudius and Gaius Norbanus dates it to 38 B.C. The story is given by Orosius (VI.20.7), and is said to be recorded in Eutropius, a 4c abridger of historical works, but this doesn't seem to be true. To an early Latin writer at any rate is surely due the added detail that this occurred in a taberna meritoria, which, etymologically at least, was a soup kitchen for old people; and very probably (Isidore, Origins, x.182) old soldiers.

From this little start the tale was told and retold thruout the Middle Ages, with embellishments, until it grew to look very much like a legend. Matters aren't helped much that no one knows what kind of oil it was — people suggest petroleum, of course, but there's not a shred of evidence — nor why or when the flow stopped, although it is said in medieval sources to have lasted only a day. Still, it wouldn't be the first time oil seeped out of the ground somewhere, and the raw fact of it here is recorded by a trustworthy writer who seems to have faithfully reproduced material from contemporaneous official lists of prodigies maintained by the authorities.

What does this have to do with the Basilica of S. Maria in Trastevere? Although one of the church's beautiful mosaics shows the oil flow from the taberna, probably not very much at all.

While we're clearing the air here, something else that doesn't have anything to do with the church: it is often stated that it was founded on the site of an oratory built by Pope St. Calixtus I, and that furthermore this is the same place of worship mentioned in the Historia Augusta (Sev. Al. 49.6) as being preferable, in the judgment of the emperor Alexander Severus, to a bar: rescripsit melius esse ut quemadmodumcumque illic deus colatur, quam popinariis dedatur. There is no evidence for either identification in this cascade, and I agree with the Catholic Encyclopedia: the nearby and very ancient church of S. Callisto is a much more plausible candidate
