We have seen[260] that the prose saga appears to have developed in Iceland in the course of the tenth century. There are indeed narratives relating both to the settlement of Iceland and to still earlier events in Norway. But these, in so far as they can be regarded as trustworthy traditions--not embellished by fiction in later times--are quite brief, and not far removed from such local or family traditions as one could find in other parts of the world. The detailed and elaborate type of story which we dealt with in Section I., and which is the distinctive feature of Icelandic literature, can hardly be traced back beyond the end of the tenth century. The prose stories of Ireland, on the other hand, are without doubt much earlier. Although we have few MSS. of Irish prose dating from a period before the twelfth century, yet it is generally agreed that many of the forms preserved, _e.g._, in the _Yellow Book of Lecan_ MS. of the Tain Bo Cualnge must be derived from an earlier MS. of not later than the seventh or early eighth century. The oral saga in Ireland is therefore of great antiquity. It may, of course, be argued that if the prose saga arose spontaneously in Ireland, there is no reason why it should not also have arisen independently in Iceland. But the existence of this form of literature in Ireland may be due to special circumstances for which Iceland offers no parallel. The oldest Irish sagas belong to that class of literature known as the heroic epic, a class which among the Teutonic peoples--as indeed among all other European peoples--makes its first appearance in verse. The exceptional treatment of this subject in Irish is all the more remarkable in view of the fact that among the Celtic peoples the _file_ or professional minstrel occupied a distinguished position in society. It would be strange if the professional minstrel were not primarily concerned with heroic epic poetry in Ireland as in other countries, since in the times to which our records refer the recitation of the heroic prose epics was one of the chief functions of the _file_.
