Baring-Gould’s sources: Roman Martyrology, and some others. Authorities:—Two lives, one of which, very ancient, is found in MS., in Lombardic characters. Both lives seem to be genuine, and may be trusted.

Of the early life of S. Barbatus nothing authentic is known. [57] He first comes before us as a priest, zealously combating the superstition of the people of Benevento, who, though nominal Christians, retained much of their ancient heathen belief. The great objects of their veneration in the city were a golden image of a viper, and a sacred tree; and Romuald, the Lombard Duke, son of the famous Grimoald, was not more enlightened than his subjects. It is said of the tree to which they offered religious honours that they were wont to hang on it the skin of a wild beast, and shoot over their shoulders at it. S. Barbatus preached for long zealously against these abuses, but with no result; however he did not desist, but joined to his exhortations fervent prayer and rigorous fasting, for the conversion of the unhappy people. At length he roused their attention by foretelling the distress of their city, and the calamities which it was to suffer from the army of the emperor Constans, who landing soon after in Italy, laid siege to Benevento. In their extreme distress, and still more grievous alarm, they listened to the holy preacher, and renounced their idolatrous practices. Thereupon S. Barbatus gave them the comfortable assurance that the siege should be raised, and the emperor worsted: which happened as he had foretold. Upon their repentance, the saint with his own hand cut down the tree, which was the object of their superstition, and afterwards melted down the golden viper which they adored, of which he made a chalice and paten for the use of the altar. Hildebrand, bishop of Benevento, dying during the siege, S. Barbatus was consecrated bishop on the 10th of March, 663. Barbatus, having been invested with the episcopal character, pursued and completed the good work he had so happily begun, and destroyed every trace of superstition in the diocese over which he presided. In the year 680, he assisted in a council held by pope Agatho at Rome, and the year following, in the sixth general council, held at Constantinople against the Monothelites. He did not long survive this great assembly, for he died on the 29th of February, 682, being about seventy years old, nineteen of which he had spent in the episcopal chair. He is honoured at Benevento among the chief patrons of the town; in Art he appears with the golden viper under his foot, and an axe in his hand.

His relics [the bodily remains of a saint, or objects they used, kept with honor] are said to be preserved in the monastery of Monte Vergine.
