John Morris's book on the "age of Arthur" was our unexpected smash hit of the summer. It's not an easy book because, for a period when historical sources are famously sparce, a lot of attention has to be paid to what we know and how we know it. And talk about your cast of thousands! But the payoff is a marvellous vision of a time when the Roman Empire lived on in Britain as it didn't in Gaul, when England, Wales, Scotland and Britanny were born, and Irish monks and their British pupils spread Christianity and learning throughout northern Europe. The history of a time when all the options were open in a way they never have been since. A good book.
A good book with interesting theories--most of which have been disproven. But if you take the whole "Arthur" thing with a grain of salt certainly some interesting views of history and using legends as a form of oral history.
