The circle has changed

The circle started small,

and came with a wall.

The unending line,

or so we thought.

Infiltrated at angles,

the circle changes.

The Unending Line,

or so we thought.

This line now, is crooked 

dented,

bifurcated,

divaricated.

It no longer forms that compact circle.

So this is,

The Unending Line,

I think.
