An evocative recreation of a vanished world, this is the first genuine narrative history for 5th Century Britain. Whereas past efforts have used unreliable legendary material to prove that some obscure sixth century ruler was the real Arthur, the present work is based on the latest scholarly research into Roman time-keeping A dispassionate analysis of the earliest sources for fifth century Britain shows that all of their chronologies were originally quite consistent but were modified by later writers to resolve apparent discrepancies in their data. The elimination of these later misconceptions provides a very accurate chronology for this most crucial and - until now - obscure century.
