On the Hunt for the Lost Wonders of Medieval Britain

Possibly interesting tidbit for fans of Arthuriana: as this quote indicates, the Historia Brittonum, like other early sources, does not refer to Arthur as a king. Elsewhere in the document, he is described as dux bellorum, which literally translates as something like "leader of battles", but which could be a nod to the Roman military title dux, one of a number of such titles that can be loosely rendered as "general".
The early Welsh stories about Arthur sometimes call him amerawdwr, which is usually translated "emperor", but which could, like the Latin imperator from which it is derived, also be translated as "commander".
As far as I know, the earliest writing to call Arthur a king is Geoffrey of Monmouth's History of the Kings of Britain, conventionally dated to 1136.
Entirely separately I have been translating another Tang Dynasty historical text[2] on Wikisource[3] and have visited and seen many of the mentioned places and cultural features: geography, people playing music on leaves or flutes, certain kinds of attire, flora and fauna, surviving remnants of period built and cultural environment such as Sanskrit carved stelae, recovered tomb ware, endemic foods and festivals, caves, neolithic paintings, etc.
