What he calls the Celtic Domain is traced from its first appearance in the Middle Europe, follows the migration trail across Western Europe into Britain and Ireland, then deals with the apparently unstoppable spread of the Roman Empire into Celtic territory and covers the major battles that resulted. Arthur and Camelot fill the final section with a new interpretation that intrigues as it develops, and ends with an Epilogue that highlights the reasons why the Celts, known-world conquerors before the Romans, could not compete with the political and military sophistication of the Roman Empire.
