Analysis of Jerusalem

If God so raise the Dead, shall He pass by
The Captive and the immemorable chain?
Fud(ce)a capta!-taken but not slain-
And cursèd not to die-ah, not to die?
Then come out of thine ages, thou art free!
Live but one Greek in old Thermopylæ,
And Greece is saved! Dark stands the Northern Fate
At Europe's open door; upon her nod
To pass that breach a hundred nations wait.
What! shall we meet her with the bayonet?
As the West sets the Sun 'twixt sea and sky
In that Great Gate, Immortal! let us set
Thy doom; quit Destiny with Destiny,
Meet Fate by Fate, and fill the gap with God.
