Thematic differences of images (to be beside the fire; to stretch out one's hand and open one's eyes/to take oneself for a king, to be covered with gold, to have a body made of glass); textual differences in the arrangement and the opposition of the paragraphs (the first plays on the distinction between insanus and demens, and on the juridical implication of demens by insanus; the second plays on the distinction 'remembering one has slept/convincing oneself that one is asleep', and on the real passage from the one to the other in a mind that applies itself to such a memory).
