Alexander III of Scotland had married Margaret, the youngest daughter of Henry III, and thus was brother-in-law to Edmund as well as to Frederick. In 1256, and while these negotiations between Henry and the Pope concerning Sicily were in progress, Alexander visited, at London, his royal father-in-law, the King of England, and his royal brother-in-law, the King of Sicily, and was received with great honors. About that time Haco, the Norse king of the Isle of Man, was defeated by Alexander III of Scotland, and killed, soon after which event (1266) the Isle of Man was ceded to the latter. The Norse coat of arms disappeared from the escutcheon of the Isle of Man, and, being replaced by the three legs of Sicily, Mr. Newton inquires: What more likely than that the King (Alexander III), when he struck the Norwegian flag, should replace it by one bearing the picturesque and striking device of Sicily, an island having so many points of resemblance with that of Man, and over which his sister ruled as Queen and her brother had been appointed as King? However little we may know concerning the method of transfer of the coat of arms from Sicily to the Isle of Man, we are not left at all in doubt as to the fact of its accomplishment; and the triskelion of Sicily became then and has been ever since, and is now, the armorial emblem of the Isle of Man. The Duke of Athol, the last proprietary of the Isle of Man, and who, in 1765, sold his rights to the Crown of England, still bears the arms of Man as the fifth quartering, "The three human legs in armor, conjoined at the upper part of the thigh and flexed in triangle, proper garnished," being a perpetuation of the triskelion or triquetrum of Sicily.[234] The arms of the Isle of Man afford an excellent illustration of the migration of symbols as maintained in the work of Count Goblet d'Alviella; but the attempt made by others to show it to be an evolution from and migration of the Swastika is a failure.
