You're welcome, Lighter.

Can't connect to that page for "copyright" reasons - and I don't have the book. If you transcribe the first verse we may be able to tell if it's a translation of Graves' poem - as may well be the case. There was a fashion for such back-creation into Irish at the end of the 19th. C - which is why I checked on Fr. Walshe, who popularised a lot of such.
