The author, Dane Pestano, based in East Sussex, England has been researching ancient world history and mythology for upwards of thirty years. Dane has been researching Arthurian material for over five years which has led to the discovery of important Irish manuscripts which may throw some light on the development of Arthurian legends and myths. The study of the Irish material has taken four years of research and the translation of old and medieval Irish into English for the first time. This current work is an introductory scholarly paper that has grown into a small book of 140 pages. It introduces for the first time the full narrative story of the Irish Arthur. The book is now available in paperback, eBook for Adobe Digital Editions, Kindle versions for UK, US and European markets and iBooks.
