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.
