THE ROMAN AGE
TIFERNUM TIBERINUM

After 283 BC, Rome annexed time after time the Umbrian people and Città di Castello, renamed Tifernum Tiberinum, was federated to Rome. The Augustan decree included it in the VI Umbrian region.
Tifernum Tiberinum was a thriving commune since the end of I century, also thanks to the munificence of its powerful patron, Pliny the younger, who in his letters wrote about the town and the surrounding landscape using admiring words.
Tifernum extended its territory on the left bank of Tiber, in a region later called Massa Trabaria, almost up to the Tiber source, and beside Savio and Marecchia.
In South-West area of the town, there was probably, the central Roman settlement. This area actually corresponds with the Prato and Mattonata neighbourhoods, where in the past, a mosaic from II century BC and in recent times, many ancient walls (possibly an amphitheatre) from the Roman era, have been found.
Several other archaeological finds are conserved in the Council Hall of the Commune. The sarcophagi conserved in the Municipal Gallery are evidence that also in the III century there were in the town, social classes able to commission high level artistic works.
Documents testifying the presence of large villas linked to the slave trade on one side and small landed properties on the other, show that the Tifernum citizen's, at least the upper classes, enjoyed excellent income during the imperial age. This economic comfort was due to the economy being based on agriculture (including viticulture), the breeding of animals, the wood harvest, directly sent by river to Rome, commerce, and also on collateral activities such as hunting and fishing.

The "Tifernate" territory, so named after Diocletian reform's (285/305 AC) was included in the "Tuscia et Umbria" province, under direct Roman administration.
This was the time of Christian diffusion. Traditional opinion says Saint Crescenziano evangelised the town and that he was martyrized in the south east of the town around the area of Pieve dè Saddi.
The first known "Episcopus Tifernas, Eudobio" was from the second half of the V centory, but the most important person in the history of the town of this period was Bishop Florido, during the reign of Pope Gregorio Magno (540/604). Saint of the Church's History, Florido rebuilt the town, of which he is now the Patron, after the destruction created by Goths and Totila.

The Dioceses enlarged its jurisdiction to create a much larger territory between the end of the VI Century and the beginning of the VII, when also, the right side Tiber lands came under the Dioceses jurisdiction including Massa Verona (Pieve Santo Stefano and Coronaro Mountain), Sovara Valley (Anghiari), Pieve di Sant'Antimo (between Citerna and Monterchi where, in that time, there was a connection road to Arezzo)
A Very important and very rare example of early Christian art (centuries V/VI) is the so called "Canoscio Sanctuary Treasure", with precious liturgical furnishings, found on 1935.
