Polaris

Slumber, watcher, till the spheres,
Six and twenty thousand years
Have revolv'd, and I return
To the spot where now I burn.
Other stars anon shall rise
To the axis of the skies;
Stars that soothe and stars that bless
With a sweet forgetfulness:
Only when my round is o'er
Shall the past disturb thy door.

 -- H.P. Lovecraft (1890–1937), from Polaris (1920)

...still the Pole Star leers down from the same place in the black vault, winking hideously like an insane watching eye which strives to convey some strange message, yet recalls nothing save that it once had a message to convey.
Sometimes, when it is cloudy, I can sleep.
