A Green and Rainless Land

It never rains here, but the land is green.
But listen close, and you may hear the sound
of caverns echoing with waters, dark, unseen
and rivers running full, deep underground.

This land is green, although it never rains.
The grass is tall and tawny from the heat.
You'll see no animal upon these plains
but dust may show the prints of passing feet.

It's strangely green, this rainless, houseless land.
No human habitation meets the eye.
The stones lie piled as if by human hands
like roofless ruins open to the sky.

This green and rainless land's secrets are hidden,
like ancient truths, forgotten or forbidden.
