It would seem that ever since James MacPherson "discovered" the poems of Ossian sometime in the 18th century there have always been some some wily Scots who found there was great craic to be had (and maybe a few shillings to be made) by inventing and forging stuff to fool the rest of us. Not that I'm complaining; the Paddies have never been behind the door when it comes to creative reinterpretation of reality.
