In the day or in the night all people has seen this sight,
On the ocean or on the plain most people has seen the same,
On this world and no other has been shown to me by my brother,
Some leader once generalized it but many things have been called it.

What am i?

Hickory-Dickory-Dock!
The mouse ran up the clock.
The clock struck one
and down did come.
Hickory-Dickory-Dock!

What am i?
--------------------------------------------------------------------
I have rivers without water,
Forest without trees,
Mountains without rocks,
Towns without houses.

What am i?
--------------------------------------------------------------------
I turn my head and you may go where you want.
I turn it again, you will stay till you rot.
I have no face, but i live or die by mycrooked teeth

Who am i?
--------------------------------------------------------------------
Iron roof, glass walls,
Burns and burns
And never falls.

What am i?
--------------------------------------------------------------------
It comes only before,
it comes only after,
Rises only in darkness,
But rises only in light,
It always the same,
But is yet always diferent.

What am i?
--------------------------------------------------------------------
A golden treasure that never stays;
The coin whose face gives wealth to all.
Strands, nuggets, and dust of gold
are all about with its shining grace...
And all more precious than any gleaming metal.

What am i?
