Found on Rocks

There are bigger words for this,
Latinate reconstructions
Suffixed to sound rather twee,

But stick with Stuff Found On Rocks.
Even calling it Rock Art
Is both anachronistic

And suggests that it could be
Commodified. The impulse
To mess around and leave marks

Preceded writing systems
By forty thousand years,
Pretty conservatively.

You don’t know where that came from,
Do you? But it’s still in you.
