MAR AND MAESWIG GLOFF OF THE NORTH: A CORRECTION OF IDENTIFICATION

Vale of York

Westmorland

Quite some time ago (in fact, I believe this first appeared in my book THE ARTHUR OF HISTORY), I wrote the following about a couple of the Men of the North:

I've since realized that I was at least partially mistaken about both chieftains.  

As both Mar and Maeswig Gloff are made the father of a prince of Elmet (an ancient kingdom around Leeds), I was right to see in Mar an attempted eponym for the Mor/Mer-ingas of Westmorland.  Maeswig, the 'Plain-fighter', appears to be a sort of personification for the broad plain that is the Vale of York.

This is important because Arthwys, the 'man of the [river] Arth' (= Irthing), is said to be Mar's son.  My best guess makes Arthur out to be Ceidio son of Arthwys.
