" 'I am a sickly man, as you see; and, because death did usually once a day knock at my door, I thought I should never be well at home; so I betook myself to a pilgrim's life, and have travelled hither from the town of Uncertain, where I and my father were born. I am a man of no strength at all of body, nor yet of mind; but would, if I could, though I can but crawl, spend my life in the pilgrim's way.
