ACT II, SCENE I.—
A dark subterranean Dungeon. To the left a cistern or reservoir, covered with
stones and rubbish. In the background, several openings in the wall, guarded
with gratings, through which can be seen the steps of a staircase, leading
from above. To the right, the door into the Prison. A lamp hanging.
[Florestan,alone. He sits on a stone: round his body is a long chain,
the end of which is fastened to the wall.
Recitative.
Alas! what darkness dense!
What horrid stillness!
Here in this dark tomb, is nothing known
But my deep anguish! Oh, most cruel torture!
Oh, Heavenly Providence, how much longer
Will this my misery last!
Air.
In the bright morning of life
My liberty, alas! was lost:
These chains are the reward
Of true and open speaking.
But what avails my lamentations?
Hopeless is my condition:
The only solace for my torments
Rests on my conscious innocence.
[Enthusiastically, but calmly.
[What feeling comes o'er me that warms my cold heart?
Wreteched, lone, imprisoned, at my own shade I start.
Oh, vision of brightness! why com'st thou to me? Behold! 'tis an angel
from Heaven I see.
T'is thou, my Leonora - Oh, thou comest to shatter my chain: Thou, only
canst cheer me to life.... back again.]
[He sinks, exhausted, upon the stony seat, concealing his jace with his
hands.
