It is this very great fecundity of the very early Irish in the production of saga and romance, in poetry and prose, which best enables us to judge of their early-developed genius, and considerable primitive culture. The introduction of Christianity neither inspired these romances nor helped to produce them; they are nearly all anterior to it, and had they been preserved to us we should now have the most remarkable body of primitive myth and saga in the whole western world. It is probably this consideration which makes M. Darmesteter say of Irish literature: "real historical documents we have none until the beginning of the decadence--a decadence so glorious, that we almost mistake it for a renaissance since the old epic sap dries up only to make place for a new budding and bourgeoning, a growth less original certainly, but scarcely less wonderful if we consider the condition of continental Europe at that date." The decadence that M. Darmesteter alludes to is the rise of the Christian schools of the fifth and sixth centuries, which put to some extent an end to the epic period by turning men's thoughts into a different channel. It is this "decadence," however, which I have preferred to examine first, just because it does rest upon real historical documents, and can be proved. We may now, however, proceed to the mass of saga, the bulk of which in its earliest forms is pagan, and the spirit of which, even in the latest texts, has been seldom quite distorted by Christian influence. This saga centres around several periods and individuals: some of these, like Tuathal and the Boru tribute, Conairé the Great and his death, have only one or two stories pertaining to them. But there are three cycles which stand out pre-eminently, and have been celebrated in more stories and sagas than the rest, and of which more remains have been preserved to us than of any of the others. These are the Mythological Circle concerning the Tuatha De Dannan and the Pre-Milesians; the Heroic, Ultonian, or Red-Branch Cycle,[2] in which Cuchulain is the dominating figure; and the Cycle of Finn mac Cúmhail, Ossian, Oscar, and the High-kings of Ireland who were their contemporaries--this cycle may be denominated the Fenian or Ossianic. [1] O'Curry was no doubt accurate, as he ever is, in this computation, but there would probably be some repetition in the stories, with lists of names and openings common to more than one, and many late poor ones. [2] M. d'Arbois de Jubainville calls this the Ulster, and calls the Ossianic the Leinster Cycle. CHAPTER XXIII THE MYTHOLOGICAL CYCLE
