In 664 a terrible epidemic called the Yellow Plague visited Scotland and carried off numbers {30} of the inhabitants. Boisil and Cuthbert were both attacked by the malady, and the lives of both were endangered. The holy prior, however, from the beginning foretold the recovery of Cuthbert and his own death. Summoning the latter to his bedside, he prophesied his future greatness, relating all that was to befall him in the years to come, and especially his elevation to the episcopal rank. Then he begged Cuthbert to assist him during the seven days of life which remained to him to finish the study of St. John's Gospel on which they had been engaged. In this they occupied themselves till St. Boisil's peaceful death. The church of St. Boswell's was dedicated to this saint, the name is a corruption of St. Boisil's. The old town has disappeared. An annual fair was formerly held on July 18th, in honour of the saint. His well also was situated there. 25--St. Cumine, Abbot, A.D. 669. He was the seventh abbot of Iona, and his learning and holiness rank him among the most illustrious monks of that renowned monastery. The Synod of Whitby, which was instrumental {31} in overthrowing the ancient Celtic computation of Easter and substituting the Roman use, occurred during Cumine's occupation of the abbacy. He wrote a life of St. Columba, probably to vindicate his sanctity after the apparent slight offered to his memory by the synod in setting aside the traditional usage which he had cherished. This life seems to have been the result of St. Colman's visit to Iona before his return to Ireland (see Feb. 18th). A more important work is St. Cumine's letter on the Easter controversy, which he wrote before he became abbot, and which shows a thorough acquaintance with the difficulties of the subject, as well as deep knowledge of the Sacred Scriptures and writings of the Fathers. He is often called _Cumine Ailbhe_ (Cumine the Fair-haired). His name survives in _Kilchuimein_ (Church of St. Cumine), the ancient designation of Fort-Augustus, and the only name by which it is still called in Gaelic. A spot in the same neighbourhood is known as St. Cumine's Return; it is in the vicinity of a hill called St. Cumine's Seat. The parish church of Glenelg also is named after this saint. MARCH 1--St. Marnock or Marnan, Bishop, A.D. 625.
