CANTO XIII

Let him, who would conceive what now I saw,
Imagine (and retain the image firm,
As mountain rock, the whilst he hears me speak),
Of stars fifteen, from midst the ethereal host
Selected, that, with lively ray serene,
O'ercome the massiest air: thereto imagine
The wain, that, in the bosom of our sky,
Spins ever on its axle night and day,
With the bright summit of that horn which swells
Due from the pole, round which the first wheel rolls,
T' have rang'd themselves in fashion of two signs
In heav'n, such as Ariadne made,
When death's chill seized her; and that one of them
Did compass in the other's beam; and both
In such sort whirl around, that each should tend
With opposite motion and, conceiving thus,
Of that true constellation, and the dance
Twofold, that circled me, he shall attain
As 't were the shadow; for things there as much
Surpass our usage, as the swiftest heav'n
Is swifter than the Chiana. There was sung
No Bacchus, and no Io Paean, but
Three Persons in the Godhead, and in one
Substance that nature and the human join'd.
