MORANN MAC MAIN'S SECOND COLLAR.

Morann had another collar, namely, a circlet that he had, like a wooden hoop. That circlet he got from Ochamon the Fool on Síd Arfemin7. For he sent him into that (fairymound), and thereout Ochamon brought that little collar. He saw in the fairy-mound that it was the thing (used) there in distinguishing between truth and falsehood. Now that collar used to be put round the foot or the hand of the person (whose guilt was in question), and if he were false it would close itself round him till it cut off his foot or his hand. But if he were innocent it would not close itself round him.
