“[A]n outstanding contribution to the study of early Irish saints and their cults … For students of early Irish literature, therefore, as well as historians, Ó Riain’s Dictionary will form part of that select group of ‘indispensable books” Thomas Charles-Edwards, Irish Historical Studies
“[A] simply splendid book, which cannot be recommended highly enough to readers, for it provides an almost complete Irish hagiography” Peter Costello, The Irish Catholic
“This dictionary, the work of more than 40 years, is an extraordinary achievement … This is an important research tool for specialist libraries and for scholars of the vast heritage of Ireland. Highly Recommended” E.J. Kealey, Choice
“It is difficult to overemphasise the importance and scope of this extraordinary piece of scholarship. Simply indispensable” Brendan Scott, Breifne
