Light and more light! The spark from heaven was there,
The flash of that reintegrating fire
Flung from heaven's altars, where all light is born,
To feed the imagination of mankind
With vision, and reveal all worlds in one.
But let no dreamer dream that his great work
Sprang, armed, like Pallas from the Thunderer's brain.
With infinite patience he must test and prove
His vision now, in those clear courts of Truth
Whose absolute laws (bemocked by shallower minds
As less than dreams, less than the faithless faith
That fears the Truth, lest Truth should slay the dream)
Are man's one guide to his transcendent heaven;
For there's no wandering splendour in the soul,
But in the highest heaven of all is one
With absolute reality. None can climb
Back to that Fount of Beauty but through pain.
Long, long he toiled, comparing first the curves
Traced by the cannon-ball as it soared and fell
With that great curving road across the sky
Traced by the sailing moon.
Was earth a loadstone
Holding them to their paths by that dark force
Whose mystery men have cloaked beneath a name?
Yet, when he came to test and prove, he found
That all the great deflections of the moon,
Her shining cadences from the path direct,
Were utterly inharmonious with the law
Of that dark force, at such a distance acting,
Measured from earth's own centre….
For three long years, Newton withheld his hope
Until that day when light was brought from France,
New light, new hope, in one small glistening fact,
Clear-cut as any diamond; and to him
Loaded with all significance, like the point
Of light that shows where constellations burn.
Picard in France—all glory to her name
Who is herself a light among all lands—
Had measured earth's diameter once more
With exquisite precision.
To the throng,
Those few corrected ciphers, his results,
Were less than nothing; yet they changed the world.
For Newton seized them and, with trembling hands,
Began to work his problem out anew.
Then, then, as on the page those figures turned
To hieroglyphs of heaven, and he beheld
The moving moon, with awful cadences
Falling into the path his law ordained,
Even to the foot and second, his hand shook
And dropped the pencil.
"Work it out for me,"
He cried to those around him; for the weight
Of that celestial music overwhelmed him;
And, on his page, those burning hieroglyphs
Were Thrones and Principalities and Powers…
For far beyond, immeasurably far
Beyond our sun, he saw that river of suns
We call the Milky Way, that glittering host
Powdering the night, each grain of solar blaze
Divided from its neighbour by a gulf
Too wide for thought to measure; each a sun
Huger than ours, with its own fleet of worlds,
Visible and invisible. Those bright throngs
That seemed dispersed like a defeated host
Through blindly wandering skies, now, at the word
Of one great dreamer, height o'er height revealed
Hints of a vaster order, and moved on
In boundless intricacies of harmony
Around one centre, deeper than all suns,
The burning throne of God.

He could not sleep. That intellect, whose wings
Dared the cold ultimate heights of Space and Time
Sank, like a wounded eagle, with dazed eyes
Back, headlong through the clouds to throb on earth.
What shaft had pierced him? That which also pierced
His great forebears—the hate of little men.
They flocked around him, and they flung their dust
Into the sensitive eyes and laughed to see
How dust could blind them.
If one prickling grain
Could so put out his vision and so torment
That delicate brain, what weakness! How the mind
That seemed to dwarf us, dwindles! Is he mad?
So buzzed the fools, whose ponderous mental wheels
Nor dust, nor grit, nor stones, nor rocks could irk
Even for an instant.
Newton could not sleep,
But all that careful malice could design
Was blindly fostered by well-meaning folly,
And great sane folk like Mr. Samuel Pepys
Canvassed his weakness and slept sound all night.
For little Samuel with his rosy face
Came chirping into a coffee-house one day
Like a plump robin, "Sir, the unhappy state
Of Mr. Isaac Newton grieves me much.
Last week I had a letter from him, filled
With strange complainings, very curious hints,
Such as, I grieve to say, are common signs
—I have observed it often—of worse to come.
He said that he could neither eat nor sleep
Because of all the embroilments he was in,
Hinting at nameless enemies. Then he begged
My pardon, very strangely. I believe
Physicians would confirm me in my fears.
'Tis very sad…. Only last night, I found
Among my papers certain lines composed
By—whom d'you think?—My lord of Halifax
(Or so dear Mrs. Porterhouse assured me)
Expressing, sir, the uttermost satisfaction
In Mr. Newton's talent. Sir, he wrote
Answering the charge that science would put out
The light of beauty, these very handsome lines:

'When Newton walked by Witham stream
There fell no chilling shade
To blight the drifting naiad's dream
Or make her garland fade.

The mist of sun was not less bright
That crowned Urania's hair.
He robbed it of its colder light,
But left the rainbow there.'

They are very neat and handsome, you'll agree.
Solid in sense as Dryden at his best,
And smooth as Waller, but with something more,—
That touch of grace, that airier elegance
Which only rank can give.
'Tis very sad
That one so nobly praised should—well, no matter!—
I am told, sir, that these troubles all began
At Cambridge, when his manuscripts were burned.
He had been working, in his curious way,
All through the night; and, in the morning greyness
Went down to chapel, leaving on his desk
A lighted candle. You can imagine it,—
A sadly sloven altar to his Muse,
Littered with papers, cups, and greasy plates
Of untouched food. I am told that he would eat
His Monday's breakfast, sir, on Tuesday morning,
Such was his absent way!
When he returned,
He found that Diamond (his little dog
Named Diamond, for a black patch near his tail)
Had overturned the candle. All his work
Was burned to ashes.
It struck him to the quick,
Though, when his terrier fawned about his feet,
He showed no anger. He was heard to say,
'O Diamond, Diamond, little do you know…'
But, from that hour, ah well, we'll say no more."

Halley was there that day, and spoke up sharply,
"Sir, there are hints and hints! Do you mean more?"
—"I do, sir," chirruped Samuel, mightily pleased
To find all eyes, for once, on his fat face.
"I fear his intellects are disordered, sir."
—"Good! That's an answer! I can deal with that.
But tell me first," quoth Halley, "why he wrote
That letter, a week ago, to Mr. Pepys."
—"Why, sir," piped Samuel, innocent of the trap,
"I had an argument in this coffee-house
Last week, with certain gentlemen, on the laws
Of chance, and what fair hopes a man might have
Of throwing six at dice. I happened to say
That Mr. Isaac Newton was my friend,
And promised I would sound him."
"Sir," said Halley,
"You'll pardon me, but I forgot to tell you
I heard, a minute since, outside these doors,
A very modish woman of the town,
Or else a most delicious lady of fashion,
A melting creature with a bold black eye,
A bosom like twin doves; and, sir, a mouth
Like a Turk's dream of Paradise. She cooed,
'Is Mr. Pepys within?' I greatly fear
That they denied you to her!"
Off ran Pepys!
"A hint's a hint," laughed Halley, "and so to bed.
But, as for Isaac Newton, let me say,
Whatever his embroilments were, he solved
With just one hour of thought, not long ago
The problem set by Leibnitz as a challenge
To all of Europe. He published his result
Anonymously, but Leibnitz, when he saw it,
Cried out, at once, old enemy as he was,
'That's Newton, none but Newton! From this claw
I know the old lion, in his midnight lair.'"
