In that deep night where Galileo groped
Like a blind giant in dreams to find what power
Held moons and planets to their constant road
Through vastness, ordered like a moving fleet;
What law so married them that they could not clash
Or sunder, but still kept their rhythmic pace
As if those ancient tales indeed were true
And some great angel helmed each gliding sphere;
Many had sought an answer. Many had caught
Gleams of the truth; and yet, as when a torch
Is waved above a multitude at night,
And shows wild streams of faces, all confused,
But not the single law that knits them all
Into an ordered nation, so our skies
For all those fragmentary glimpses, whirled
In chaos, till one eagle-spirit soared,
Found the one law that bound them all in one,
And through that awful unity upraised
The soul to That which made and guides them all.

Did Newton, dreaming in his orchard there
Beside the dreaming Witham, see the moon
Burn like a huge gold apple in the boughs
And wonder why should moons not fall like fruit?
Or did he see as those old tales declare
(Those fairy-tales that gather form and fire
Till, in one jewel, they pack the whole bright world)
A ripe fruit fall from some immortal tree
Of knowledge, while he wondered at what height
Would this earth-magnet lose its darkling power?
Would not the fruit fall earthward, though it grew
High o'er the hills as yonder brightening cloud?
Would not the selfsame power that plucked the fruit
Draw the white moon, then, sailing in the blue?
Then, in one flash, as light and song are born,
And the soul wakes, he saw it—this dark earth
Holding the moon that else would fly through space
To her sure orbit, as a stone is held
In a whirled sling; and, by the selfsame power,
Her sister planets guiding all their moons;
While, exquisitely balanced and controlled
In one vast system, moons and planets wheeled
Around one sovran majesty, the sun.
