When Constans landed with a certain force at Tarentum, he found the Lombards in possession of the duchy of Beneventum. A legend said that their king Autharis after a bold march through the Peninsula to the Straits of Messina, had spurred his horse into the sea and exclaimed, “This shall be the Lombard boundary”. But his successors had never made good the words of Autharis. Naples and Amalfi, Sorrentum, Gaeta, and Tarentum had imperial governors. Alboin however made a duchy of Beneventum which then included the ancient Samnium and Apulia, and portions of Campania and Lucania. It was a stronghold of Lombard robbers in southern Italy. Constans tried to expel the young duke Romuald. But he failed, and hearing that King Grimoald was approaching to aid his son, he went to Naples, left at Formiæ, the present Mola di Gaeta, 20,000 men, and marched on Rome by the Appian Way. Pope Vitalian went out to meet him as legitimate Roman emperor. It was true that ten years before he had seized Pope St. Martin in his church, and carried him off by stealth to trial, suffering, and ultimate martyrdom in the Crimea. It was true likewise that while holding St. Martin in prison, he had repeated the evil deed committed by Justinian’s empress Theodora, a hundred and sixteen years before, and compelled the Roman clergy under threat of worse things to elect a new Pope while the Pope was living, though in this case the elected was himself blameless and excellent. It is true, also, that later still he had treated the great confessor Maximus with equal cruelty. But these crimes did not prevent his being the actual emperor to whom loyal submission was due from the great throne of justice in the earth. It would seem also by the mode in which Constans had received the nuntios who bore Pope Vitalian’s synodical letter, announcing his accession, and by the superb present which he sent back in acknowledgement, that somehow a better spirit prevailed at the moment towards the Pope. We are met indeed by the fact that the Monothelite patriarch Peter held the see of Constantinople for twelve years from the death of the re-established Pyrrhus in 654, to his own death in 666, being the fourth heretic in succession from Sergius in the see of the royal city. Constans approached Rome at the head of an army. He made his offerings as emperor to the three great churches of Rome, the Lateran, St. Peter’s and St. Mary Major. The Pope was completely at his mercy. He lodged in the imperial palace on the Palatine, which, however great its desolation, was able at least to receive him. In his twelve days sojourn he laid his hands upon every bronze statue which he thought worth plundering: and he stripped of its costly roof the church which his predecessor sixty years before had given to the Pope, dedicated to the Mother of God and all Martyrs.
