Analysis of Clouds

Clouds in the skies above, heavenly wanderers,
Long strings of snowy pearls stretched over azure plains!
Exiles like I, you rush farther and farther on,
Leaving my dear North, go distances measureless.
What drives you southward? Is't envy that covertly
Prods you or malice whose arrows strike openly?
Destiny is it? A crime hanging over you?
Or friendship's honeyed but poisonous calumny?
No! O'er those barren wastes heedlessly journeying,
Passion you know not or anguish or punishment;
Feeling you lack, you are free - free eternally,
You have no homeland, for you there's no banishment.
