I’m a sucker for these models of a messy real world thing that attempt to explain it all; particularly if they include a drawing.

Anecdote of the Jar
Wallace Stevens

I placed a jar in Tennessee,
And round it was, upon a hill.
It made the slovenly wilderness
Surround that hill.

The wilderness rose up to it,
And sprawled around, no longer wild.
The jar was round upon the ground
And tall and of a port in air.

It took dominion every where.
The jar was gray and bare.
It did not give of bird or bush,
Like nothing else in Tennessee.
