The identity of Karl or Kali Hundason is one of the historical puzzles which exercise the ingenuity of modern historians. Supposing the Saga name of this individual to be a Norse corruption of the name of a Scottish king, it resembles none more nearly than that of Culen Induffson, the Culen Mac Induff of the _Chronica Pictorum_. But if Kali Hundason be intended for Culen Induffson, the dates do not agree by more than sixty years. On the other hand, supposing the events here narrated to be of the period assigned to them by the Saga, Kali Hundason ought to be Duncan, son of Crinan, Abbot of Dunkeld, who was the grandson and successor of King Malcolm Mac Kenneth. But Fordun states that Duncan’s succession was a peaceful one. It is not to be overlooked, however, that Earl Thorfinn was also a grandson of Malcolm Mac Kenneth; and if we could account for the discrepancy as to the name given by the Saga, the war between the two grandsons of the deceased monarch might readily be accounted for. For full details of the speculations regarding the identity of Kali Hundason, see Skene’s Highlanders of Scotland, chap. v.; the Irish version of “Nennius” (Irish Archæological Society), Appendix, p. 78; Robertson’s Scotland under her Early Kings, vol. ii. p. 477; and Munch’s Norske Folks Historie, vol. i. pt. 2, p. 854. Footnote 253: The words “at Beruvik” in Jonæus’s edition are not in the Flateyjarbók. Two places of this name are mentioned in the Saga. One of these is plainly Berwick-on-Tweed (chap. xcii.) The locality of the other (which must be the “Beruvik” of this passage) is fixed by the statement in chap. xciv., where it is said that Earl Rögnvald was then in Sutherland celebrating the marriage of his daughter with Eirik Slagbrellir; and when word was brought to him that Harald had come to Thurso, he rode with a number of his followers “from Beruvik to Thurso.” It has been conjectured that the place here indicated was _Caistal a Bharruick_, an old square tower situated on an eminence near Kirkiboll, on the east side of the shore of the Kyle of Tongue (_Orig. Parochiales_, vol. ii. p. 717). Judging from the context, however, it seems more likely that it may have been the _vik_ or inlet at the mouth of the water of Berriedale (Berudal), on the southern border of Caithness, where there are also the ruins of an old square tower—the Castle of Berriedale. This agrees with the statement that King Kali, sailing _northward_ from Beruvik, saw the sails of Thorfinn’s ships going towards Deerness, as he sailed into the mouth of the Firth from the east. Had Kali come from the Kyle of Tongue, he would have sailed _east_, and Thorfinn would have seen and intercepted him from Duncansbay. Footnote 254: Now Sandwick, in Deerness, Orkney.
