Moist, bright, and green, the landscape laughs around.
Full swell the woods; their every music wakes,
Mix’d in wild concert, with the warbling brooks
Increased, the distant bleatings of the hills,
And hollow lows responsive from the vales,
Whence, blending all, the sweeten’d zephyr springs.
Meantime, refracted from yon eastern cloud,
Bestriding earth, the grand ethereal bow
Shoots up immense; and every hue unfolds,
In fair proportion running from the red
To where the violet fades into the sky.
Here, awful Newton, the dissolving clouds
Form, fronting on the sun, thy showery prism;
And to the sage-instructed eye unfold
The various twine of light, by thee disclosed
From the white mingling maze. Not so the boy;
He wondering views the bright enchantment bend,
Delightful, o’er the radiant fields, and runs
To catch the falling glory; but amazed
Beholds th’ amusive arch before him fly,
Then vanish quite away.
James Thomson, The rainbow, 1735
