Yea, in the shaping of a grain of sand,
He sees the law that made the spheres to be-
Sees atom-worlds spun by the Hidden Hand,
To whirl about their small Alcyone.

With spell of wizard Science on his eyes,
And augment on his arm, he probes through space;
Or pushes back the low, unfriendly skies,
To feel the wind of Saturn on his face.

He walks abroad upon the Zodiac,
To weigh the worlds in balances, to fuse
Suns in his crucible, and carry back
The spheral music and the cosmic news.

—Markham
