A vision on his sleep
There came, a dream of hopes that never yet
Had flushed his cheek. He dreamed a veiled maid
Sate near him, talking in low solemn tones.
Her voice was like the voice of his own soul
Heard in the calm of thought; its music long,
Like woven sounds of streams and breezes, held
His inmost sense suspended in its web
Of many-colored woof and shifting hues.
Knowledge and truth and virtue were her theme,
And lofty hopes of divine liberty,
Thoughts the most dear to him, and poesy,
Herself a poet. Soon the solemn mood
Of her pure mind kindled through all her frame
A permeating fire; wild numbers then
She raised, with voice stifled in tremulous sobs
Subdued by its own pathos; her fair hands
Were bare alone, sweeping from some strange harp
Strange symphony, and in their branching veins
The eloquent blood told an ineffable tale.
The beating of her heart was heard to fill
The pauses of her music, and her breath
Tumultuously accorded with those fits
Of intermitted song. Sudden she rose,
As if her heart impatiently endured
Its bursting burden; at the sound he turned,
And saw by the warm light of their own life
Her glowing limbs beneath the sinuous veil
Of woven wind, her outspread arms now bare,
Her dark locks floating in the breath of night,
Her beamy bending eyes, her parted lips
Outstretched, and pale, and quivering eagerly.
His strong heart sunk and sickened with excess
Of love. He reared his shuddering limbs, and quelled
His gasping breath, and spread his arms to meet
Her panting bosom:–she drew back awhile,
Then, yielding to the irresistible joy,
With frantic gesture and short breathless cry
Folded his frame in her dissolving arms.
Now blackness veiled his dizzy eyes, and night
Involved and swallowed up the vision; sleep,
Like a dark flood suspended in its course,
Rolled back its impulse on his vacant brain.
