Searching the skiey depths all night in vain,
The starry seer hath known this mystery—
That the sky orb, which over half the sky
Hath baulked his chase, and mocked his utmost pain
If (haply while the daylight poured amain
Into the empty concave of the night)
Hath stepped into his glass, as clear to sight
As the one tree that stars a glassy plain,
So is it known that some secretive Truth,
Which Thought and Patience strove in vain to find,
