_Prince Cuglas._
In the list of the historic tales mentioned in the Book of Leinster,
and which is given in O'Curry's appendix to his "Lectures on the MSS.
Materials of Ancient Irish History," "The Cave of the Road of Cuglas"
finds place. O'Curry has the following note:--
"Cuglas was the son of Donn Desa, King of Leinster, and master of the
hounds to the monarch Conaire Mor. Having one day followed the chase
from Tara to this road, the chase suddenly disappeared in a cave, into
which he followed, and was _never seen after_. Hence the cave was
called _Uaimh Bealach Conglais_, or the cave of the road of Cuglas
(now Baltinglass, in the County of Wicklow). It is about this cave,
nevertheless, that so many of our pretended Irish antiquarians have
written so much nonsense in connection with some imaginary pagan
worship to which they gravely assure the world, on etymological
authority, the spot was devoted. The authority for the legend of
Cuglas is the _Dinnoean Chus_ on the place _Bealach Conglais_ (Book of
Lecain). The full tale has not come down to us."
