Tuto

Saint Tuto was a monk and abbot of the monastery of Saint Emmeram in Regensburg, Germany, and then the ninth bishop of Regensburg, from 893 until his death on 10 October 930. The Orthodox calendar commemorates him on 14 May.

He was of noble birth and had close ties with the last Carolingians, Arnulf of Carinthia and Louis. From them he received important gifts. Arnulf gave the monastery the Codex Aureus, which King Conrad took back and later returned. Tuto commissioned for the monastery a golden altar adorned with a thousand precious stones. In 894 he took part in the assembly of Bavarian bishops at Reisbach, where they told Pope Formosus of their opposition to creating separate dioceses in Moravia.

He helped the Christianization of Bohemia, in connection with Saint Wenceslas. Wenceslas called him to Prague to advise on a memorial for his grandmother Ludmila, who died in 921, and later Tuto consecrated the church of Saint Vitus in Prague in 925. He saw the building of the castle of Stauf, between 914 and 930, as a defence against the Hungarians. He and the rulers are buried in the monastery.
