The first part of the guide is a brief history, starting at the time of the Roman invasion in AD 43 when most of Britain was inhabited by Britons or Brythons
Rhys comments that "the words here cited are very suggestive, for without explicitly saying that Arthur was one of the kings of the Brythons
, they make him the general or dux bellorum, in whom one readily recognises the superior officer, known in the time of Roman rule as the Comes Britanniae" (xi).
So people's common sense of Britishness doesn't need a British state to sustain it either; the ancient Brythons
knew little of the Act of Union."
It might start with the Picts or perhaps the Beaker People, tell of the tribes and kingdoms of the Brythons
and Gaels, their relations with the wider world and the impact of later invaders, and trace the development of all these cultural groups down to the present day.
Shakespeare based the play upon the legendary pre-historic Celtic chieftain, Leir of the Brythons, whose life the medieval Welsh historian Geoffrey of Monmouth recounted in his Historia Regum Britanniae (The History of the Kings of Britain).
In the book, Geoffrey chronicled the lives of the kings of the Brythons in a narrative spanning more than 2,000 years, beginning with the founding the Brythonic nation and continuing through to the Anglo-Saxon invasions.
The Roman Empire was the superpower of its day and after many years of occupation the Brythons must have thought that Roman power would never wane, that Latin would always be the predominant worldwide language.
Many Brythons may have lost their language to embrace Roman culture.
The Angles and the Saxons called the indigenous population 'Britons' irrespective of them being Brythons
, Goedels or Picts.
First were the Cruithni Picts, followed by the Goedels and the Brythons
, each superimposing their language and culture on the other.
Sadly one recent historian has offered us another Anglo Saxon Chronicle by ignoring the Brythons
and another has suggested that the Brythons
remained in land which is now England, conquered by a few Anglo Saxon bands, and had willingly abandoned their own culture in favour of the superior Germanic culture and history - no suggestion of ethnic cleansing!
