The One and the Three explores parallels between Byzantine and early Irish monastic traditions, finding in both a markedly trinitarian theology founded on God's contemplation and ascetic experience. Chrysostom Koutloumousianos refutes modern theological theses that affect ecclesiology, and contrasts current schools of theological thought with patristic theology and anthropology, in order to approach the meaning and reality of unity and otherness within the Triadic Monad and the cosmos. He explores such topics as the connection between nature and person, the esoteric dimension of the Self, the relation and dialectic of impersonal institutions and personal charisma, and perennial monastic virtues as ways to unity in diversity.

Dietz finds that this period of Christianity witnessed an explosion of travel, as men and women took to the roads, seeking spiritual meaning in a life of itinerancy. This book is essential reading for those who study the history of monasticism, for it was a monastic context that religious travel first claimed an essential place within Christianity.

The field of Hiberno-Latin literature, a term coined to describe the Latin literature written in Ireland, or by Irishmen abroad, between 400 and 1500, was first defined by the late Mario Esposito. His work, too, revealed its vast extent and range, so enabling a significantly better understanding of the importance of Irish scholarship in the cultural history of the Western Middle Ages. This volume concentrates on Hiberno-Latin authors, and on texts composed in Ireland; a second collection of Esposito’s articles contains studies on Irish learning and texts written on the Continent. The great strength of his research is that it is founded on unparalleled knowledge of the manuscripts - many of which, indeed, no longer survive. The articles, now provided with extensive indexes to facilitate their consultation, therefore form the essential basis and guide for any further enquiry into the authors dealt with or their works.
