THE MANIAC. (1840)
Words in part by Monk Lewis; music by Henry Russell, ©1840.

Hush! 'tis the night watch; he guards my lonely cell!
Hush! 'tis the night watch; hush, 'tis the night watch.
Hush! Hush! He come to guard, to guard my lonely cell!
He comes, he comes this way. Yes, 'tis the night watch!
Yes 'tis the night watch; his glimmering lamp I see.
Hush 'tis the night watch—softly he comes.
Hush! Hush!

No, by Heaven—no, by Heaven, I am not mad!
Oh, release me—oh, release me!
No, by Heaven—no, by Heaven, I am not mad!

I loved her sincerely; I loved her too dearly.
I loved her in sorrow, in joy, and in pain.
But my heart is forsaken, yet ever will awaken
The memory of bliss which ne'er will come again.
Oh, my poor heart is broken—oh, my poor heart is broken!
I see her dancing in the hall—I see her dancing in the hall.
I see her dancing—she heeds me not.

No, by Heaven, &c.

He quits the grate—he turns the key.
He quits the grate; I knelt in vain.
His glimmering lamp still, still I see,
And all, and all is gloom again!
Cold, bitter cold! No life—no light.
Life, all thy comforts once I had,
But here I am chained this freezing night.

No, by Heaven, &c.

For lo! You, while I speak,
Mark how yon demon's eyeballs glare.
He sees me now; with dreadful shriek
He whirls, he whirls me in the air.
Horror! The reptile strikes his tooth
Deep in my heart, so crushed and sad!
Aye, laugh, ye fiends! Laugh, laugh, ye fiends!

Yes, by Heaven—yes, by Heaven, they've driven me mad!
I see her dancing in the hall! I—ha, ha, ha, ha ha!
Oh, release me—oh, release me; she heeds me not!
Yes, by Heaven—yes, by Heaven, they've driven me mad!
