We never see the same sky twice.
No fixed mark, this maddening gyre.
And though it seems to swirl entire,
note: wanderers will blunder through
on retrograde and showy loops
before rejoining a forward track.
The Earth itself has shifted tack
since pyramid or henge aligned.
While looking up now we may find
a little bear has its tail pinned
but it will anon escape.
Even stars jostle on the charts
and inch along on ancient courses
a priceless herd of luminous horses
in an infinite pasture.
We never see the same sky twice
even with members of the same crowd.
And that’s not to mention clouds.
