Celts, Gaels, and Britons offers a miscellany of essays exploring three closely connected areas within the fields of Celtic Studies in order to shed new light on the ancient and medieval Celtic languages and their literatures. Taking as its inspiration the scholarship of Professor Patrick Sims-Williams, to whom this volume is dedicated, the papers gathered together here explore the Continental Celtic languages, texts from the Irish Sea world, and the literature and linguistics of the British languages, among them Welsh and Cornish. With essays from eighteen leading scholars in the field, this in-depth volume serves not only as a monument to the rich and varied career of Sims-Williams, but also offers a wealth of commentary and information to present significant primary research and reconsiderations of existing scholarship.
