Bishop and Confessor in Scotland, b. on the island of Bute, date unknown; d. 590. His feast is kept on 10 August. He was a nephew of St. Cathan, and was educated in Ireland under Sts. Comgall and Kenneth; he became a monk, went to Scotland, and eventually was bishop among the Picts. Several miracles are related of him, among them the restoration of a dead boy to life. The Aberdeen Breviary gives these and other details of the saint’s life, which are rejected however, by the Bollandists. There can be no doubt that devotion to St. Blane was, from early times, popular in Scotland. His monastery became the site of the Cathedral of Dunblane. There was a church of St. Blane in Dumfries and another at Kilblane. The year of the saint’s death is variously given as 446, 590, and 1000; 446 (Butler, Lives of the Saints) is evidently incorrect; the date 1000, found in Adam King, “Kalendar of Scottish Saints” (Paris, 1588), in Dempster, “Menologium Scotorum” (Bonn, 1622), and in the “Acta SS.”, seems to have crept in by confusing St. Kenneth, whose disciple Blane was, with a Kenneth who was King of Scotland about A.D. 1000. The highest authorities say the saint died 590. The ruins of his church at Kingarth, Bute, where his remains were buried, are still standing and form an object of great interest to antiquarians; the bell of his monastery is preserved at Dunblane.
