Hath tried his prowess, and come off with shame,
And where I would not have you lose your life,
Against no man, but furious fiend of hell.
Ralph. Speak on, Sir Knight, tell what he is, and where:
For here I vow upon my blazing badge,
Never to lose a day in quietness;
But bread and water will I only eat,
And the green herb and rock shall be my couch,
Till I have quell'd that man, or beast, or fiend,
That works such damage to all errant knights.
