The huge and microscopic career of time

William Carlos Williams, from Spring and All, 1923:

In that huge and microscopic career of time, as it were a wild horse racing in an illimitable pampa under the stars, describing immense and microscopic circles with his hoofs on the solid turf, running without a stop for the millionth part of a second until he is aged and worn to a heap of skin, bones and ragged hoofs—In that majestic progress of life, that gives the exact impression of Phidias’ frieze, the men and beasts of which, though they seem of the rigidity of marble are not so but move, with blinding rapidity, though we do not have the time to notice it, their legs advancing a millionth part of an inch every fifty thousand years—In that progress of life which seems stillness itself in the mass of its movements—at last SPRING is approaching.
