Giraldus Cambrensis tells us (Opera, vol. v. p. 119) that Irishmen can be changed into wolves. Nennius asserts that the descendants of wolves are still in Ossory, and they retransform themselves into wolves when they bite. (Wonders of Eri, xiv.)
These Ossory men-wolves are of the race of Laighne Fxlaidh.
