RT Article T1 Saint Cadoc, Saint Docco and Saint Oudoceus JF The journal of religious history, literature and culture VO 5 IS 1 SP 1 OP 25 A1 Thornhill, Philip LA English PB University of Wales Press YR 2019 UL https://ixtheo.de/Record/166918921X AB St Docco appears in early Irish sources where we might expect Cadoc, whose cult therefore may be suspected to have displaced his. The hypothesis is advanced that St Docco was the dominant cult-figure of South East Wales before Cadoc, as the patron of an episcopal establishment more, or less, directly associated with Llandough, near the sub-Roman fort of Cardiff and the future episcopal centre of Llandaff. It is suggested that a successor to this establishment based at Llandogo latterly adopted, as a new patron, bishop Eudoce or Oudoceus, who had been an actual seventh century bishop 'of Sancti Docunni'. This patron-figure was then used by the Llandaff propagandists to help provide a bogus episcopal heritage for their new see, substituting in a sense for Saint Docco who had genuinely been the patron saint of an anciently important episcopal institution, like the other two pillars of Llandaff's bogus episcopal heritage, Teilo and Dubricius. Specific features in certain of the Llandaff charters suggest that manipulation has obscured an original 'bishop of St Docco'. K1 CADOC K1 DOCCO K1 LLANDAFF K1 LLANDOUGH K1 OUDOCEUS
