S. Thierry was born at Château Thierry, so called from an ancestor of the saint, whose family was noble and wealthy. He was taken to court and gained the confidence of King Robert the Good. On the death of Bishop Arnulf of Orleans, Thierry was elected, with the consent of the king, to fill the vacant see. His appointment was opposed by a priest named Adalric who had desired the throne for himself, and who had the indecency to burst into the church with a band of armed men, and thrust up to the very altar, uttering violent menaces, when Thierry was being consecrated, in the hopes of terrifying the consecrating bishops from what they were doing. Afterwards the priest at the head of a party of ruffians waylaid the Bishop by night, in a lane, and throwing him from his horse, ran him through, as they believed, with a sword. The weapon providentially cut through his garments without wounding him; and when the would-be assassins had fled, he rose and regained the city. Adalric, fearing the consequences, threw himself on the compassion of the Bishop, and asked his pardon, which Thierry frankly accorded him. Thierry died on a journey at Tonnerre, where his kinsman Count Milo built the church of S. Michael over his body. He was succeeded on the throne of Orleans by the priest Adalric.
