"Apologeticum atque rescriptum Claudii episcopi adversus Theutmirum abbatem": the historical context of the creation of the text and problems of source studies

The publication is a commented Russian translation of the " Apologe ticum atque rescriptum Claudii episcopi adversus Theutmirum abbatem " attributed to Claudius, the Bishop of Turin (†827 or 828). Created in the 820s, the text has survived only in fragments. It sparked intense controversy: Claudius’s opponents — Dungal of Bobbio and Jonas of Orléans, who identified numerous deviations from orthodox Church doctrine in the work and accused Claudius of iconoclasm. Although Claudius of Turin was not condemned for heresy during his lifetime, his name was added to the Catholic Church’s Index Librorum Prohibitorum in 1557. The translation is provided with an introductory article, which gives the historical context of the creation of the text, as well as touches on the problems of source studies.
