Arising from a conference held in NUI, Galway, this book brings together experts from archaeology, history, toponomy, anthropology, ethnography, and early Irish literature in the study of kingship and royal landscapes in early Ireland. Sacral kings, such as the kings of Tara, held exceptional kingships that are replicated throughout the world. These kings bore responsibility for maintaining harmony between the human and the divine. Features of this early stage in the development of kingship endured long after the conversion to Christianity, linked through common facets with biblical kingship and surviving as motifs in the ceremonies surrounding the institution of medieval Irish kingship. This volume examines the exercise of kingship in literature and in the morphology of sites in Ireland (Tara, Rathcroghan, Uisnech, Cashel, and Cornashee) and elsewhere.
