Among the Highlanders themselves various traditions have existed as to the origin of the clans. Mr Skene mentions the three principal ones, and proves them to be entirely fanciful. The first of these is the _Scottish_ or _Irish_ system, by which the clans trace their origin or foundation to early Irish or Scoto-Irish kings. The second is what Mr Skene terms the _heroic_ system, by which many of the Highland clans are deduced from the great heroes in the fabulous histories of Scotland and Ireland, by identifying one of these fabulous heroes with an ancestor of the clan of the same name. The third system did not spring up till the 17th century, “when the fabulous history of Scotland first began to be doubted, when it was considered to be a principal merit in an antiquarian to display his scepticism as to all the old traditions of the country.”[118] Mr Skene terms it the _Norwegian_ or _Danish_ system, and it was the result of a _furor_ for imputing everything and deriving everybody from the Danes. The idea, however, never obtained any great credit in the Highlands. The conclusion to which Mr Skene comes is, “that the Highland clans are not of different or foreign origin, but that they were a part of the original nation, who have inhabited the mountains of Scotland as far back as the memory of man, or the records of history can reach; that they were divided into several great tribes possessing their hereditary chiefs; and that it was only when the line of these chiefs became extinct, and Saxon nobles came into their place, that the Highland clans appeared in the peculiar situation and character in which they were afterwards found.” Mr Skene thinks this conclusion strongly corroborated by the fact that there can be traced existing in the Highlands, even so late as the 16th century, a still older tradition than that of the Irish origin of the clans. This tradition is found in the often referred to letter of “John Elder, clerk, a Reddschanke,” dated 1542, and addressed to King Henry VIII. This tradition, held by the Highlanders of the “more auncient stoke” in opposition to the “Papistical curside spiritualite of Scotland,” was that they were the true descendants of the ancient Picts, then known as “Redd Schankes.”
