Analysis of Another Love

OF her I thought who now is gone so far:
And, the thought passing over, to fall thence
Was like a fall from spirit into sense
Or from the heaven of heavens to sun and star.
None other than Love's self ordained the bar
'Twixt her and me; so that if, going hence,
I met her, it could only seem a dense
Film of the brain,—just nought, as phantoms are.
Now when I passed your threshold and came in,
And glanced where you were sitting, and did see
Your tresses in these braids and your hands thus,—
I knew that other figure, grieved and thin,
That seemed there, yea that was there, could not be,
Though like God's wrath it stood dividing us.
