Magnus was occupied during the ensuing winter amongst the Sudreys, or Southern Hebrides, in securing the conquests of the preceding summer and in arranging a treaty with the Scottish king, who is said by some authorities to have admitted the pretensions of the Norwegian monarch to the whole of the islands in the western seas. To such an arrangement (if it were ever made) Edgar could have offered no valid objection, as the majority of the islands could hardly be said, at this time, to have ever been included amongst the dependencies of the Scottish crown. It is further stated that the king of Norway established his claim to his new possessions by sailing round each of them separately; and he is even said to have been dragged across the isthmus at Loch Tarbert in a boat, with his hand upon the tiller, in order to include Cantyre amongst the islands--a story probably invented at a later period to account for the severance of that district from the mainland possessions of the Oirir Gael, and its lengthened occupation by the Gallgael in dependence on the Norsemen and their kings.[201] [Sidenote: A.D. 1099] Magnus returned to Norway in the following summer, leaving Sigurd in his new Iarldom; and he was occupied during the next three years in warring against the Swedes, until peace was concluded, and cemented by his marriage with a daughter of the Swedish king Inge. But his former successes amongst the Hebrides had inflamed him with the desire of further conquests in the same quarter, and hardly had he ratified his alliance with Sweden before he again fitted out a fleet, to be directed on this occasion against the Irish coasts. [Sidenote: A. D. 1102.] Murketagh O’Brien, collecting the men of Munster and Leth-Mogh, prepared to oppose the invasion; but an arrangement was soon effected between the kings, by which the daughter of Murketagh was given to Sigurd Magnusson, whilst the claims of that prince upon the allegiance of the Dublin Norsemen were probably supported by the Irish king.[202] [Sidenote: A. D. 1103.]
