The Dun Book of Magh Meall, Part One (2011), told of the birth and development of the Children of Light, in the "Land of Immensity." Here, in Part Two, we follow their adventures as they sail over the great Mother Sea, in pursuit of the mystery that lies beyond the horizon. The manuscript of The Dun Book purports to have been written in the second century which, if true, makes it the oldest example of Irish Immram, or 'voyage, ' literature that we possess. It may have served as the prototype for the later immrama; e.g., 'The Voyage of Bran, ' 'The Voyage of Mael Duin, ' and 'The Voyage of St. Brendan.' Combining both poetry and prose, The Dun Book, Part Two, refines and redefines our understanding of ancient Irish myth and legend. It is a book of transformation. On the surface, it describes the transformation from the idyllic world of Thesidiline, to other realms among the Myriad Worlds. At a deeper level, the book symbolically describes the process of Druidic initiation, or the mystical process of utilizing knowledge, memory, and imagination to bring about druimmne, or 'wisdom'. The Dun Book of Magh Meall is a book to be savored by students of mythology, Celtica, linguistics, anthropology, Irish literature, Druidism, or by anyone with a sense of literary adventure."
