The Scots' continual resort to mythmaking, from medieval times down to the 19th century, seems to Trevor-Roper to demonstrate an essential truth about the Celtic mind, as opposed to the Anglo-Saxon. Drawing on an old but resilient stereotype, he contrasts English prosiness with Celtic imagination. Yes, he admits, the English "have created one of the great literatures of the world. Yet, have they a single myth that they can call their own?" Surely it is no accident that all the great mythic heroes of the British Isles, from Cymbeline to King Arthur, were invented by the Celtic peoples — the Welsh, Scots, and Irish — who inhabited the land before the Anglo-Saxon invasion.
