19. 
She spake in language whose strange melody
Might not belong to earth.  I heard alone, 290
What made its music more melodious be,
The pity and the love of every tone;
But to the Snake those accents sweet were known
His native tongue and hers; nor did he beat
The hoar spray idly then, but winding on 295
Through the green shadows of the waves that meet
Near to the shore, did pause beside her snowy feet.

20. 
Then on the sands the Woman sate again,
And wept and clasped her hands, and all between,
Renewed the unintelligible strain 300
Of her melodious voice and eloquent mien;
And she unveiled her bosom, and the green
And glancing shadows of the sea did play
O’er its marmoreal depth:—­one moment seen,
For ere the next, the Serpent did obey 305
Her voice, and, coiled in rest in her embrace it lay.

21. 
Then she arose, and smiled on me with eyes
Serene yet sorrowing, like that planet fair,
While yet the daylight lingereth in the skies
Which cleaves with arrowy beams the dark-red air, 310
And said:  ’To grieve is wise, but the despair
Was weak and vain which led thee here from sleep: 
This shalt thou know, and more, if thou dost dare
With me and with this Serpent, o’er the deep,
A voyage divine and strange, companionship to keep.’ 315

22. 
Her voice was like the wildest, saddest tone,
Yet sweet, of some loved voice heard long ago. 
I wept.  ’Shall this fair woman all alone,
Over the sea with that fierce Serpent go? 
His head is on her heart, and who can know 320
How soon he may devour his feeble prey?’—­
Such were my thoughts, when the tide gan to flow;
And that strange boat like the moon’s shade did sway
Amid reflected stars that in the waters lay:—­

23. 
A boat of rare device, which had no sail 325
But its own curved prow of thin moonstone,
Wrought like a web of texture fine and frail,
To catch those gentlest winds which are not known
To breathe, but by the steady speed alone
With which it cleaves the sparkling sea; and now 330
We are embarked—­the mountains hang and frown
Over the starry deep that gleams below,
A vast and dim expanse, as o’er the waves we go.

24. 
And as we sailed, a strange and awful tale
That Woman told, like such mysterious dream 335
As makes the slumberer’s cheek with wonder pale! 
’Twas midnight, and around, a shoreless stream,
Wide ocean rolled, when that majestic theme
Shrined in her heart found utterance, and she bent
Her looks on mine; those eyes a kindling beam 340
Of love divine into my spirit sent,
And ere her lips could move, made the air eloquent.
