Analysis of A Thrush Before Dawn

A voice peals in this end of night
A phrase of notes resembling stars,
Single and spiritual notes of light.
What call they at my window-bars?
The South, the past, the day to be,
An ancient infelicity.

Darkling, deliberate, what sings
This wonderful one, alone, at peace?
What wilder things than song, what things
Sweeter than youth, clearer than Greece,
Dearer than Italy, untold
Delight, and freshness centuries old?

And first first-loves, a multitude,
The exaltation of their pain;
Ancestral childhood long renewed;
And midnights of invisible rain;
And gardens, gardens, night and day,
Gardens and childhood all the way.

What Middle Ages passionate,
O passionless voice!    What distant bells
Lodged in the hills, what palace state
Illyrian!    For it speaks, it tells,
Without desire, without dismay,
Some morrow and some yesterday.

All-natural things!    But more-Whence came
This yet remoter mystery?
How do these starry notes proclaim
A graver still divinity?
This hope, this sanctity of fear?
O innocent throat!    O human ear!
