Funny, I thought 'wledig' means 'mighty'. Or at least my geiriadur says so. Oh, and I've never seen any 'Celtic' (Greek nomenclature for western barbarians) knotwork in my life, that normally attributed as being 'Celtic' is in fact Norse/Danish/Anglish/Saxon knotwork involving elaborate animal designs. Iron Age Western European (read: Celtic) artwork typically involved abstract swirls, spirals, and curvilinear designs, most pointedly never crossing themselves.
