It's a beautiful--but very strange--song As with many of Dylan's songs, I'm not sure I understand it, and I'm not sure I need to.
Farewell Angelina
The bells of the crown
Are being stolen by bandits
I must follow the sound
The triangle tingles
And the trumpets play slow
Farewell Angelina
The sky is on fire
And I must go
It's not exactly clear what the relationship between Angelina and the singer is, or why he has to follow or why the sky is on fire. But apparently he's trying to persuade her not to be angry about it:
There’s no need for anger
There’s no need for blame
There’s nothing to prove
Ev’rything’s still the same
Just a table standing empty
By the edge of the sea
Farewell Angelina
The sky is trembling
And I must leave
Then things get even stranger (although I always thought this verse is a reference to Alice in Wonderland):
The jacks and the queens
Have forsaked the courtyard
Fifty-two gypsies
Now file past the guards
In the space where the deuce
And the ace once ran wild
Farewell Angelina
The sky is folding
I’ll see you in a while
The next two verses don't make things any clearer, either:
See the cross-eyed pirates sitting
Perched in the sun
Shooting tin cans
With a sawed-off shotgun
And the neighbors they clap
And they cheer with each blast
Farewell Angelina
The sky’s changing color
And I must leave fast
King Kong, little elves
On the rooftops they dance
Valentino-type tangos
While the makeup man’s hands
Shut the eyes of the dead
Not to embarrass anyone
Farewell Angelina
The sky is embarrassed
And I must be gone
And then we come to the end...
The machine guns are roaring
The puppets heave rocks
The fiends nail time bombs
To the hands of the clocks
Call me any name you like
I will never deny it
Farewell Angelina
The sky is erupting
I must go where it’s quiet
So the sky is the recurring image here. It's successively "on fire," "trembling," "folding," "changing color," "embarrassed," and "erupting." It's never calm or peaceful. I think the sky must be the singer's metaphor for the state of his relationship with Angelina...which is clearly not a soothing one. And eventually, he tells her not just that he's leaving, but where he must go, and, implicitly, why. I think.
