Why are areas of Britain known by their Anglo-Saxon names as opposed to the Celtic names that Merdynn would have known them by?
As referred to in the book – Merdynn was able to see what transpired in Britain after his imprisonment and his vision only gradually dimmed as the early centuries passed so he would have seen how Britain eventually became settled by the Saxons, Angles et al. As to why he actually used the Saxon names rather than the Celtic versions, well, perhaps he felt the old Celtic tribal names no longer represented what the land had become.
