The secret fount of fire, whose bubbles went
Over the ferrule's brim, and manward sent
Art's mighty means and perfect rudiment,
That sin I expiate in this agony,
Hung here in fetters, 'neath the blanching sky.
Ah, ah me! what a sound,
What a fragrance sweeps up from a pinion unseen
Of a god, or a mortal, or nature between,
Sweeping up to this rock where the earth has her bound,
To have sight of my pangs, or some guerdon obtain--
