THE KASÎDAH II, 1, 8

In these drear wastes of sea-born land,
 these wilds where none may dwell but He,
What visionary Pasts revive,
 what process of the Years we see:

Gazing beyond the thin blue line
 that rims the far horizon-ring,
Our sadden’d sight why haunt these ghosts,
 whence do these spectral shadows spring?
