Les Delices de Cumbria - Part II

It's been brought to my attention that the medieval German poet Wolfram von Eschenbach sets much of his great holy-grail romance 'Parzifal' in a part of north Britain he insists on calling 'Cucumberland'.
Well, Dan Brown's obviously missed a trick here . . .
Though it's good to know that the reputation of our vegetable produce had spread as far afield as Germany in the early 13th Century.
