The Green Castle

In a castle of translucent walls

Full of flash and brilliance,

When there is light,

And thick with shadow

When there is not

You will search in vain for water

Which might assuage your thirst

You will lay your body

Against wall or floor

Seeking illusive coolness there

But in these deep green depths

There is always fever:

The heat rising

From within the heart

Of a perfect emerald.
