Florence, however, seems to have been--in spite of Villani's describing it as the Chamber of the Empire and the like--a place of very slight importance under the Empire. Tacitus mentions that a deputation was sent from Florentia to Tiberius to prevent the Chiana being turned into the Arno. Christianity is said to have been first introduced in the days of Nero; the Decian persecution raged here as elsewhere, and the soil was hallowed with the blood of the martyr, Miniatus. Christian worship is said to have been first offered up on the hill where a stately eleventh century Basilica now bears his name. When the greater peace of the Church was established under Constantine, a church dedicated to the Baptist on the site of the Martian temple and a basilica outside the walls, where now stands San Lorenzo, were among the earliest churches in Tuscany. In the year 405, the Goth leader Rhadagaisus, _omnium antiquorum praesentiumque hostium longe immanissimus_, as Orosius calls him, suddenly inundated Italy with more than 200,000 Goths, vowing to sacrifice all the blood of the Romans to his gods. In their terror the Romans seemed about to return to their old paganism, since Christ had failed to protect them. _Fervent tota urbe blasphemiae_, writes Orosius. They advanced towards Rome through the Tuscan Apennines, and are said to have besieged Florence, though there is no hint of this in Orosius. On the approach of Stilicho, at the head of thirty legions with a large force of barbarian auxiliaries, Rhadagaisus and his hordes--miraculously struck helpless with terror, as Orosius implies--let themselves be hemmed in in the mountains behind Fiesole, and all perished, by famine and exhaustion rather than by the sword. Villani ascribes the salvation of Florence to the prayers of its bishop, Zenobius, and adds that as this victory of "the Romans and Florentines" took place on the feast of the virgin martyr Reparata, her name was given to the church afterwards to become the Cathedral of Florence.
