Patton, abbot of Amabaric, in Scotland, passing into Germany to preach the gospel, and being chosen bishop of Verdun, Tanco, who had served God many years in that abbey in great reputation for his singular learning and piety, was raised to the dignity of abbot. Out of an ardent thirst after martyrdom, he resigned this charge, and followed his countryman and predecessor into Germany, where, after some time, he succeeded him in the see of Verdun, of which he was the third bishop. His success in propagating the faith was exceedingly great, but it was to him a subject of inexpressible grief to see many who professed themselves Christians, live enslaved to shameful passions. In order to convert, or at least to confound them, he preached a most zealous sermon against the vices which reigned amongst them; at which a barbarous mob was so enraged as fiercely to assault him; and one of them, stabbing him with a lance, procured him the glorious crown of martyrdom, about the year 815. This account of him is given us by Krantzius.
