13. Now there were the twelve bishops[19] of Ireland in the school of
Findian in Cluain Iraird, _ut dixit_,
Two Findians, holy Colums two,
Ciaran, Cainnech, Comgall fair;
Two Brenainns, Ruadan bright of hue,
Ninned, Mo-Bi, Mac Natfraeich there.
This was their rule, that every bishop[19] should grind at the quern
on his day. But angels used to grind at the quern for Ciaran's sake on
the day that was his.
