Now will I seek again to bring to mind How porous a body all things have- a fact Made manifest in my first canto, too. For, truly, though to know this doth import For many things, yet for this very thing On which straightway I'm going to discourse, 'Tis needful most of all to make it sure That naught's at hand but body mixed with void. A first ensample: in grottos, rocks o'erhead Sweat moisture and distil the oozy drops; Likewise, from all our body seeps the sweat; There grows the beard, and along our members all And along our frame the hairs. Through all our veins Disseminates the foods, and gives increase And aliment down to the extreme parts, Even to the tiniest finger-nails. Likewise, Through solid bronze the cold and fiery heat We feel to pass; likewise, we feel them pass Through gold, through silver, when we clasp in hand The brimming goblets. And, again, there flit Voices through houses' hedging walls of stone; Odour seeps through, and cold, and heat of fire That's wont to penetrate even strength of iron. Again, where corselet of the sky girds round . . . . . . And at same time, some Influence of bane, When from Beyond 'thas stolen into [our world]. And tempests, gathering from the earth and sky, Back to the sky and earth absorbed retire- With reason, since there's naught that's fashioned not With body porous.
