Now fair and spangled in the sudden light,
And clinging with wide arms for fear of fall;
Now dark and shelter'd by a kindly pall
Of dusky shadow from his wakeful foe;
Slowly he winds adown—dimly and small,
Watch'd by the gentle Swan that sings below,
Her hope increasing, still, the larger he doth grow.

But nine times nine the serpent folds embrace
The marble walls about—which he must tread
