That is, a proof which they used at that time to distinguish between truth and falsehood, namely, Waiting at an Altar, that is, to go nine times round the altars, and afterwards to drink water over which a wizard's incantation had been uttered. Now if (the accused) were guilty the token of his sin was manifest upon him. But if he were innocent (the water) would do him no harm. Now Cai Cainbrethach, — the pupil of Fenius Farsaid, the twelfth, or the seventy-second, disciple of the school which Fenius collected from the Greeks in order to learn the many languages throughout the countries of the world, — it was that Cai who brought this ordeal from the land of Israel when he came to the Tuath Déa, and he had learned the law of Moses, and it was he that delivered judgments in the school after it had been gathered together from every side, and it is he that ordained the ‘Judgment of Cai.’ It was that same Cai, moreover, who first ordained in Erin the Law of the Four Tracks, for only two of the school came to Erin, namely, Amergin White-knee the poet and Cai the judge. And Cai remained in Erin until he had outlived nine generations, in consequence of the righteousness of his judgments, for the judgments which he used to deliver were judgments of the Law of Moses, and therefore the judgments of the Law are very abundant in the Fénechas10. They were judgments of the Law (of Moses), then, that served for Cormac.
