Swan and Shadow Swan

Thus did I by the water's brink
Another world beneath me think;
And while the lofty spacious skies
Reversèd there, abused mine eyes,
I fancied other feet
Came mine to touch or meet;
As by some puddle I did play
Another world within it lay.

By walking men's reversèd feet
I chanced another world to meet;
Though it did not to view exceed
A phantom, 'tis a world indeed;
Where skies beneath us shine,
And earth by art divine
Another face presents below,
Where people's feet against ours go.

Within the regions of the air,
Compassed about with heavens fair,
Great tracts of land there may be found
Enriched with fields and fertile ground;
Where many numerous hosts
In those far distant coasts,
For other great and glorious ends
Inhabit, my yet unknown friends.
