“This impeccably composed, immensely informative text is the only work of its kind to date and will undoubtedly be regarded as an essential publication by enthusiasts and researchers alike. The detailed yet accessible nature of the text means that it is an invaluable stand-alone publication and also contributes greatly to the larger corpus of Irish medieval research”. Clare Busher O’Sullivan, volume 29 (for 2020) of the Journal of Irish Archaeology
