To the memory of Sir Isaac Newton (extraits)

All intellectual eye, our solar-round
First gazing through, he by the blended power
Of gravitation and projection saw
The whole in silent harmony revolve.
From unassisted vision hid, the moons
To cheer remoter planets numerous pour'd,
By him in all their mingled tracts were seen.
He also fix'd the wandering Queen of Night,
Whether she wanes into a scanty orb,
Or, waxing broad, with her pale shadowy light,
In a soft deluge overflows the sky.
Her every motion clear-discerning, he
Adjusted to the mutual main, and taught
Why now the mighty mass of water swells
Resistless, heaving on the broken rocks,
And the full river turning; till again
The tide revertive, unattracted, leaves
A yellow waste of idle sands behind.
Then breaking hence, he took his ardent flight
Through the blue infinite; and every star,
Which the clear concave of a winter's night
Pours on the eye, or astronomic tube,
Far-stretching, snatches from the dark abyss,
Or such as farther in successive skies
To fancy shine alone, at his approach
Blaz'd into suns, the living centre each
Of an harmonious system: all combin'd,
And rul'd unerring by that single power,
Which draws the stone projected to the ground.
O unprofuse magnificence divine !
O wisdom truly perfect ! thus to call
From a few causes such a scheme of things,
Effects so various, beautiful, and great,
An universe complete ! and O belov'd
Of Heaven! whose well-purg'd penetrative eye,
The mystic veil transpiercing, inly scann'd
The rising, moving, wide-establish'd frame.


He, first of men, with awful wing pursu'd
The comet through the long elliptic curve,
As round innumerous worlds he wound his way,
Till, to the forehead of our evening sky
Return'd, the blazing wonder glares anew,
And o'er the trembling nations shakes dismay.


The heavens are all his own, from the wild rule
Of whirling vortices and circling spheres
To their first great simplicity restor'd.
The schools astonish'd stood; but found it vain
To keep at odds with demonstration strong,
And, unawaken'd, dream beneath the blaze
Of truth. At once their pleasing visions fled,
With the gay shadows of the morning mix'd,
When Newton rose, our philosophic sun !
Th' aërial flow of sound was known to him,
From whence it first in wavy circles breaks,
Till the touch'd organ takes the message in.
Nor could the darting beam of speed immense
Escape his swift pursuit and measuring eye.
Ev'n Light itself, which every thing displays,
Shone undiscover'd, till his brighter mind
Untwisted all the shining robe of day ;
And, from the whitening undistinguish'd blaze,
Collecting every ray into his kind,
To the charm'd eye educ'd the gorgeous train
Of parent colours. First the flaming red
Sprung vivid forth; the tawny orange next ;
And next delicious yellow; by whose side
Fell the kind beams of all-refreshing green.
Then the pure blue, that swells autumnal skies
Ethereal played; and then, of sadder hue,
Emerg'd the deepen'd indigo, as when
The heavy-skirted evening droops with frost ;
While the last gleamings of refracted light
Died in the fainting violet away.
These, when the clouds distil the rosy shower,
Shine out distinct adown the wat'ry bow ;
While o'er our heads the dewy vision bends
Delightful, melting on the fields beneath.
Myriads of mingling dyes from these result,
And myriads still remain -- infinite source
Of beauty, ever flushing, ever new.

James Thomson, A Poem Sacred to the Memory of Sir Isaac Newton (1727)
