At their collapse to primal forms of stuff. Lo, the rains perish which Ether-father throws Down to the bosom of Earth-mother; but then Upsprings the shining grain, and boughs are green Amid the trees, and trees themselves wax big And lade themselves with fruits; and hence in turn The race of man and all the wild are fed; Hence joyful cities thrive with boys and girls; And leafy woodlands echo with new birds; Hence cattle, fat and drowsy, lay their bulk Along the joyous pastures whilst the drops Of white ooze trickle from distended bags; Hence the young scamper on their weakling joints Along the tender herbs, fresh hearts afrisk With warm new milk. Thus naught of what so seems Perishes utterly, since Nature ever Upbuilds one thing from other, suffering naught To come to birth but through some other's death. ***** And now, since I have taught that things cannot Be born from nothing, nor the same, when born, To nothing be recalled, doubt not my words, Because our eyes no primal germs perceive; For mark those bodies which, though known to be In this our world, are yet invisible: The winds infuriate lash our face and frame, Unseen, and swamp huge ships and rend the clouds, Or, eddying wildly down, bestrew the plains With mighty trees, or scour the mountain tops With forest-crackling blasts. Thus on they rave With uproar shrill and ominous moan. The winds, 'Tis clear, are sightless bodies sweeping through The sea, the lands, the clouds along the sky, Vexing and whirling and seizing all amain; And forth they flow and pile destruction round, Even as the water's soft and supple bulk Becoming a river of abounding floods, Which a wide downpour from the lofty hills Swells with big showers, dashes headlong down Fragments of woodland and whole branching trees; Nor can the solid bridges bide the shock As on the waters whelm: the turbulent stream, Strong with a hundred rains, beats round the piers, Crashes with havoc, and rolls beneath its waves Down-toppled masonry and ponderous stone, Hurling away whatever would oppose. Even so must move the blasts of all the winds, Which, when they spread, like to a mighty flood, Hither or thither, drive things on before And hurl to ground with still renewed assault, Or sometimes in their circling vortex seize And bear in cones of whirlwind down the world: The winds are sightless bodies and naught else-- Since both in works and ways they rival well The mighty rivers, the visible in form. Then too we know the varied smells of things Yet never to our nostrils see them come; With eyes we view not burning heats, nor cold, Nor are we wont men's voices to behold. Yet these must be corporeal at the base,
