Age of Arthur A History of the British Isles from 350 to 650 Book

I've long been interested in the history of Roman Britain as well as in the 'Matter of Britain', Arthurian literature and Grail legends, but I've done little previous study of the history of the islands between the years of change covered in this lengthy tome. Although mentioning Arthur in the title, very little is actually detailed about this legendary king. Although author Morris believes his existence incontrovertible, his treatment of the man is as a symbol of the end of the old British/Roman culture and the beginning of what became the English (the various Saxons), Welsh (what the British became) and Irish cultures. Lacking much original documentary evidence for this transitional period, the author relies heavily on archaeology and sophisticated critical exegesis of later texts. For me, so ignorant of the period, reading this book was slow and often difficult. I'd not recommend it to others with a similarly weak background. Specialists, however, should be quite impressed.
