As he that layeth siege to well-walled town, And flanked about with solid bulwarks, still Renews the assault; now fain would batter down Gateway or tower; now gaping fosse would fill;
Yet vainly toils (for entrance is there none)
And wastes his host, aye frustrate of his will;
So sorely toils and strives without avail The damsel, nor can open plate or mail.
