These two poems came from an exercise we were given in my Poetry Workshop group.  We were given five words (I don't remember how they were selected) and had to work all five into each of two stanzas.  The words were plain / shadow / mountain / light / glass.

1/
The lengthening shadow of the mountain
stretches across the plain.
The last sunlight reflects on the lake like glass.

I drain my glass.
The shadow of death looms over me like a mountain.
My future is plain. I move towards the light.

2/
Peering through my magic glass,
lights and shadows play again,
tuppence coloured, penny plain.
Explorers cross the mountain pass.

Over valley, over mountain,
sunlight now breaks out again.
What was shadowed now is plain,
like drops of glass the tinkling fountain.
