“. . . Down thither, prone in flight
He speeds, and through the vast ethereal sky
Sails between worlds and worlds, with steady wing,
Now on the polar winds, then with quick fan
Winnows the buxom air; till within soar
Of towering eagles, to all the fowls he seems
A Phœnix, gazed by all; as that sole bird
When, to enshrine his relics in the sun’s
Bright temple, to Egyptian Thebes he flies.”
