first of these was the dislike of Christianity to transmit whatever directly preserved the memory of the old divinities. In the surviving stories their divinity is not too closely descried; they are made as human as possible, though they are still superhuman in power and deed; they are tolerated as a kind of fairy-folk rather than as gods. Yet they are more than fairies and they have none of the wretchedness of the decrepit, skinclad Zeus of Heine's Gods in Exile. Side by side with this there was another tendency, natural to a people who no longer worshipped gods whose names were still more or less familiar. They were regarded as kings and chiefs and were brought into a genealogical scheme, while some myths were reduced to annals of supposititious events. Myth was transmuted into pseudo-history. This euhemerizing37 process is found in all decaying mythologies, but it is outstanding in that of the ancient Irish. The third factor is the attempt of Christian scribes to connect the mythical past and its characters with persons and events of early Scriptural history. These factors have obscured Irish divine legends, though enough remains to show how rich and beautiful the mythology had been. In the two heroic cycles—those of Cúchulainn and Fionn respectively—the disturbance has been less, and in these the Celtic magic and glamour are found. Some stories of the gods escaped these destructive factors, and in them these delectable traits are also apparent. They are romantic tales rather than myths, though their mythical quality is obvious.
Two mythical strata exist, one older and purely pagan, in which gods are immortal, though myth may occasionally have spoken of their death; the other influenced by the annalistic scheme and also by Christianity, in which, though the unlikeness of the gods to humankind is emphasized, yet they may be overcome and killed by men. The literary class who rewrote the myths had less simple ideals than even the Greek mythographers. They imagined some moving situations and majestic episodes or borrowed these from the old myths, but they had
