Arthurian Links with Herefordshire

Say, have you thought what manner of man it is
Of whom men say: ‘He could strike giants down’,
Or what strong memories over Time’s abyss
Bore up the pomp of Camelot and the Crown?

And why one banner all the background fills,
Beyond the pageant of so many spears,
And by what witchery in the western hills
A throne stands empty for a thousand years?
