It is said that when the Holy Patricius (St. Patrick) was preaching Christianity in that land, there was one great race more hostile to him than the other people that were in the land. And these men tried to do him many kinds of injury. And when he preached Christianity to them as other men, and came to meet them when they were holding their assembly, then they took this counsel, to howl at him like wolves.

But when he saw that his message would succeed little with these people, then he became very wroth, and prayed God that he might avenge it on them by some judgement, that their descendents might forever remember their disobedience. And great punishment and fit and very wonderful has since befallen their descendants; for it is said that all men who come from that race are always wolves at a certain time, and run into the woods and take food like wolves; and they are worse in this that they have human reason, for all their cunning, and such desire and greed for men as for other creatures.

And it is said that some become so every seventh year, and are men during the interval. And some have it so long that they have seven years at once, and are never so afterwards.
