Note 48 — INTRODUCTION

I formerly disputed this identification, on the ground that the archbishop of Cashel who was present at Fiadh meic Oengusa was O'Dunan (G. T. Stokes, Ireland and the Celtic Church, ed. 6, 1907, p. 372). I am now convinced that he was archbishop of Cashel. I was not then aware that all MSS. of Keating date the Synod of Rathbreasail in 1110.
