In this box is a mystery
What’s inside is history
The only one who may ever know
Live a long time ago
As you wonder where it may be
But first you really need the key

With golden lines all around
And just the perfect hint of brown
The box is as blue as night sky
And can not be seen by the human eye
For it is in the darkest of caves
Possibly getting hit by waves

For all I know about this box
It shows up during one (winter) equinox
It will shine so very bright
But only for that one short night
For when the moon is high
Up in the night sky

Only then you’ll know
That the box will show
The path to the cave
If you are very brave
Then you may know what’s in the box
Just behind the rocks…
