I asked the wind,
Do you know the limits of the sky?
And the wind whispered,
It is up there ,and very high!
As high till you see its shades of blue!
And beyond that, I haven't a clue!
All I know it's black at a place I never can go!
Ask the Moon as she might know!

And the Moon was shy ,had a veil on her face,
Of shadows and reflections of obscured grace!
As I asked her if she know where the black sky did end!
She said ask the planets and their heavenly friends!

As I asked many planets and their satellite Moons
The asteroids, space rocks and those comets that flew...
