For lo, what think you? suddenly
The rain and the wind ceased, and the sky
Received at once the full fruition
Of the moon's consummate apparition.
The black cloud-barricade was riven,
Ruined beneath her feet, and driven
Deep in the West; while, bare and breathless,
North and South and East lay ready
For a glorious thing that, dauntless, deathless,
Sprang across them and stood steady.
'Twas a moon-rainbow, vast and perfect,
From heaven to heaven extending, perfect
As the mother-moon's self, full in face.
It rose, distinctly at the base
With its seven proper colours chorded,
Which still, in the rising, were compressed,
Until at last they coalesced,
And supreme the spectral creature lorded
In a triumph of whitest white,—
Above which intervened the night.
But above night too, like only the next,
The second of a wondrous sequence,
Reaching in rare and rarer frequence,
Till the heaven of heavens were circumflexed,
Another rainbow rose, a mightier,
Fainter, flushier and flightier,—
Rapture dying along its verge.
Oh, whose foot shall I see emerge,
Whose, from the straining topmost dark,
On to the keystone of that arc?
