“Ó Cathasaigh’s work combines aspects of the traditional philological and etymological studies of early Irish myth and saga with interpretations of these works as literary works in their own right. Ó Cathasaigh is an excellent guide through the complexities of early Irish literature, whether it be on general issues such as he addresses his essays on The Semantics of síd, The Concept of the Hero in Early Irish Literature, and Early Irish Literature and Law, or more specific themes, such as ‘Cath Maige Tuired’ as Exemplary Myth, Mythology in ‘Táin Bó Cúailgne’, and The Rhetoric of ‘Fingal Rónáin’.” —Fabula “This collection of essays, originally published between 1976 and 2011, reflects the life’s work of one of the most perceptive and subtle readers of early Irish literature of the last fifty years . . . . Ó Cathasaigh’s expository style, his close reading of a wide range of texts, and the enduring authority of these essays certainly does provide the reader with a lucid guide to some of the most important debates and texts in the field.” —SHARP News “This is a book that should be acquired by anyone who is concerned with the study of early Irish literature . . . . This is a very special book, indeed, its sum greater than its already outstanding parts.” —Parergon “This book is a credit to its editor, publisher, and (above all) to its author, whose perceptive interpretations and civilized discussions lead the reader to an appreciation of the breadth of early Irish saga literature. It is a book that can and should be read by all those who seek insight into the literature and culture of medieval Ireland.” —breac: A Digital Journal of Irish Studies "To read Tomás Ó Cathasaigh’s essays gathered and ordered in this splendid volume is to explore the web of early Irish literature with a learned and witty guide. Each chapter stops at a particular point in the early Irish literary record, but the light that Ó Cathasaigh sheds on each text or theme illumines the entirety of the landscape. His close attention to the nuances of language and his finely tuned sense of social relationships in medieval Ireland are but two of the qualities that make Ó Cathasaigh perhaps the most skilled reader that early Irish literature has ever had. Coire Sois will be an indispensable vade mecum for generations of students and scholars to come." —Catherine McKenna, Margaret Brooks Robinson Professor of Celtic Languages and Literatures, Harvard University "Tomás Ó Cathasaigh has long been known for his sensitive and superbly nuanced readings of early Irish literature. This impeccably edited collection brings together his most important articles of the past thirty years, many of which appeared originally in anthologies and periodicals not always easy to find outside Ireland. Ó Cathasaigh's deep learning and profound insights are evident on every page. This is truly a 'must-have' book both for specialists in Celtic and for all medievalists interested in vernacular culture and the intersection of native and Latin traditions." —Robin Stacey, University of Washington "A turning-point in Celtic studies occurred in 1981 when Tomás Ó Cathasaigh began a series of thematic studies of Irish sagas, starting with ‘The Theme of Lommrad.’ Now, three decades later, his ground-breaking collection of essays has been gathered together in a book. The student experience has been transformed. No essay or article on Irish sagas can be written without consulting Professor Ó Cathasaigh’s close readings. We are all in debt to him, Matthieu Boyd, and the University of Notre Dame Press." —Patrick Sims-Williams, Aberystwyth University, Wales “Tomás Ó Cathasaigh is that rare scholar in Celtic studies whose work has much to say not only to advanced scholars in the field but also to specialists dealing with other literatures, comparative mythologists, and undergraduates. Our understanding of medieval Irish epic and saga is immeasurably enriched by his elegant writing style, his erudition, and his wide-ranging critical eye. It is indeed a bounteous blessing, then, to have collected in this volume Ó Cathasaigh’s best, most representative, and most useful work." —Joseph Nagy, University of California, Los Angeles
