In these four lines, Death appears as an enormous, almost parental figure, and human beings are children playing between his legs. Our breathing itself becomes a schoolboy prank — small, rowdy, and doomed to end. We go further and “scrawl challenge on his sodden boots,” like kids daring a giant to notice them. It is an image of defiance that is both funny and pathetic: we talk back to the one force we cannot outrun. Meanwhile, Death isn’t even watching. He is quietly coiling his cypress-roots, the tree associated with mourning, as if preparing to trip us up or root us in the ground. The speaker’s tone is wry rather than terrified; he seems amused by human courage and fully aware that it changes nothing. The mood is darkly comic, compact, and a little eerie — the joke of life told from the shadow of the ending.

Between the mighty legs of Death We play the schoolboy pranks of breath ; Scrawl challenge on his sodden boots. The while he coils his cypress-roots.
