Did shroud unutterable things:

One, a fair angel, in the skies

Of whose serene, unshadowed eyes

Were seen the lights of Paradise.

To these, in turn, he gave the whole

Vast empire of his brooding soul;

Now, filled with strains of heavenly swell,

Now thrilled with awful tones of hell:

Wide were his being’s strange extremes,

’Twixt nether glooms, and Eden gleams
