[84] _Chron. Sax._ 949. _Innes_, Ap. 3. The seventh year of Malcolm corresponds exactly with 949, the year in which Olave reappeared in Northumbria, and the curious tradition preserved in the old chronicle that Constantine resumed his authority for a week to head the Scottish army in an incursion to the Tees, must surely be connected with the arrival of his son-in-law, and the reluctance of Malcolm to break the engagement by which he held Cumberland. [85] _A. F. M._, 950. _Chron. Sax._ 952. [86] _Tigh._ 980. _A. F. M._, 1014. The account of Tighernach reveals both the extent of Olave’s power and the far greater importance of the first victory which broke it. The death of the old warrior is described rather quaintly by the annalist “post pœnitentiam et _bonos mores_.” [87] _Chron. Sax._ 954. _Sim. Dun. de Gestis_, 1072. _Wendover_, vol. i., p. 402. _Heimskringla, Saga_ 4, c. 4. The Henricus and Reginaldus of Wendover are probably the Harek and Rognwald of the Saga. Simeon calls Maco or Maccus a son of Olave, but Olave had no son of that name, and Maco was probably “Maccus Archipirata,” or Magnus Haraldson, king of Man and the Islands, who was the head of a different branch of the Hy Ivar. His father, Harald, who was killed in Connaught in 940, was the son of Sitric _Mac_ Ivar, or the elder Sitric, who killed, or was killed by, his brother Godfrey, and was the head of the Norsemen of Limerick. The power of the Limerick Hy Ivar appears to have received a severe shock when Olave Godfreyson, shortly before the battle of Brunanburgh, destroyed all their ships and captured their leader, Olave Cen-Cairedh. _A. F. M._, 934, 938.
