Where does the Sun go

Elba, Magazzini '97 

Where does the Sun go
when it goes over the mountain
Where does it go?

Where does the Sun go
when it falls over backwards
Where does it go?

When it falls over backwards
it crawls under the earth
to rise in the morning
on the other side of the valley.

Does the sun roll down the valley
like a penny
or a ginger biscuit?

D'you think if I walked over the mountain
into the valley I would find the sun asleep on its back?
