in Etain's form, among them Ess, Eochaid's daughter; but Eochald mistook her for Etain and by her had a daughter Mess Buachalla, mother of Conaire. Recognizing his mistake, he went to Midir, who restored Etain to him; and in revenge Siugmall, Midir's grandson, afterwards killed Eochaid.6
Although folk-tale formulae are found in this story, it is based on myths of divine love and magic power and of a goddess's rebirth as a mortal. Midir's poetic description of the gods' land is archaic and may only later have been connected with the underground síd. Curious, too, is the idea, which we have noted above, of the subjection of gods to mortals— performing tasks and permitting their abode to be spoiled or a consort taken from them—but it may reflect the belief in magic power to which even divinities must yield. Nevertheless, the deities get their own back: Etain's recapture is preceded by the incest incident; Midir is slain; and his descendant, Conaire, dies because the god causes him to break his tabus, as already described.

The next incident is obscurely told In version c, but comparing it with the other, it is evident that the hunters en-
