Still longed for, never seen.

To Keats the vista unfolded of the past reached far beyond his own time:

The voice I hear this passing night was heard

In ancient days by emperor and clown;

Perhaps the self-same song that found a path

Through the sad heart of Ruth, when sick for home,

She stood in tears amid the alien corn;

The same that oft-times hath

Charmed magic easements, opening on the foam

Of perilous seas, in faery lands forlorn.
