Note 1 — PREFACE

The prominence accorded to this class of stories in the early literature of Ireland is not to be wondered at when the economic situation of the country and the stage of civilization of which they are the faithful mirror is borne in mind.1 Since all wars are waged for gain, and since among the Irish, who are still very much a nation of cattle raisers, cattle was the chief article of wealth and measure of value,2 so marauding expeditions from one district into another for cattle must have been of frequent occurrence, just as among the North American Indians tribal wars used to be waged for the acquisition of horses. That this had been a common practice among their kinsmen on the Continent also we learn from Caesar's account of the Germans (and Celts?) who, he says, practised warfare not only for a means of subsistence but also for exercising their warriors. How long-lived the custom has been amongst the Gaelic Celts, as an occupation or as a pastime, is evident not only from the plundering incursions or "creaghs"3 as they are called in the Highlands and described by Scott in Waverley and The Fair Maid of Perth, but also from the "cattle-drives" which have been resorted to in our own day in Ireland, though these latter had a different motive than plunder. As has been observed by Sir Henry Sumner Maine, Lord Macaulay was mistaken in ascribing this custom to "some native vice of Irish character," for, as every student of ancient Ireland may perceive, it is rather to be regarded as "a survival, an ancient and inveterate habit" of the race.
