Terni listen is an ancient town of Italy, capital of Terni province in southern Umbria, in the plain of the Nera river. It is 104 km (65 mi) N of Rome, 36 km (23 mi) NW of Rieti, and 29 km (18 mi) S of Spoleto. The city was probably founded in the 7th century BC by the Sabini. In the 3rd century BC it was conquered by the Romans and soon become an important municipium lying on the Via Flaminia. The Roman name was Interamna, meaning “in between two rivers”. During the Roman Empire the city was enriched with several buildings, including aqueducts, walls, amphitheaters, temples and bridges. After the Lombard conquest (755) Terni lost any role of prominence, reducing to a secondary town in the Duchy of Spoleto. In 1174 it was again destroyed by Frederick Barbarossa‘s general, Archbishop Christian of Mainz. In the following century Terni was one of the favourite seat of St. Francis‘ prayings.
The name “Valentine” (Priest Valentio) does not occur in the earliest list of Roman martyrs, compiled by the Chronographer of 354. The feast of St. Valentine was first established in 496 by Pope Gelasius I, who included Valentine among those “… whose names are justly reverenced among men, but whose acts are known only to God.” As Gelasius implied, nothing was known, even then, about the lives of any of these martyrs. The Saint Valentine that appears in various martyrologies in connection with February 14 is described either as: A priest in Rome, A bishop of Interamna (modern Terni), or A martyr in the Roman province of Africa. Saint Valentine (in Latin, Valentinus) is the name of several martyred saints of ancient Rome. The name “Valentine”, derived from valens (worthy, strong, powerful), was popular in Late Antiquity. Of the Saint Valentine whose feast is on February 14, nothing is known except his name and that he was buried at the Via Flaminia north of Rome on February 14. It is even uncertain whether the feast of that day celebrates only one saint or more saints of the same name. For this reason this liturgical commemoration was not kept in the Catholic calendar of saints for universal liturgical veneration as revised in 1969. But “Martyr Valentinus the Presbyter and those with him at Rome” remains in the list of saints proposed for veneration by all Catholics.
