B. Constantine II., King of Scotland, Martyr
HE marched against the infidels who advanced to plunder his dominions, and, intercepting the forces of Hubba, cut off from the army of his brother, king Hinguar, by a sudden flood of the river Lenin, easily put them to flight; but was afterward vanquished by Hinguar, near the town Cararia, and slain. In his last moments he repeated those words of the Psalm lxxvii. 19. Lord Jesus, abandon not to beasts the souls which serve thee. His death is placed by bishop Lesley and Buchanan in 874. He was buried in the isle of Iona, or Y-Colm-kill, and his tomb is said to have been honoured with miracles. The title of martyr is given him by King, in his Calendar, on the 11th of March, the day on which he was honoured under that quality at St. Andrews. See Lesley, Hist. l. 5. Buchanan, l. 6.
