You say you want to know me?

The prism? The glass?

I am a parrallelogram.

I am unknowable.

I do not create light;

I reflect it and distort it

To my devices.

Sometimes brilliantly,

Seemingly accidentally,

But always ordered, by design.

I am not a mystery.

I am a complex structure of glass

With a triangular section

Specializing in decomposing light.

Sometimes dazzling

And utimately, fragile.
