Significant contributions on Celtic history, law, archaeology and literature. Thomas Charles-Edwards, the distinguished scholar of medieval Britain and Ireland, has made important contributions to a number of fields, but is particularly renowned for his studies in Celtic history and law. In this volume, colleagues pay tribute to his work with essays that range across the medieval Celtic world, including medieval Wales, Ireland and Scotland. In the first part of the volume, they cover historical aspects (and, as is fitting, often reflect the honorand's interest in archaeology and epigraphy); in the second, they focus on medieval Irish and Welsh legal institutions and texts, which are used by some to inform new readings of literary texts.
