It gave its name to an age
and though humanity
has turned the page
to other materials
it still has a place.
Members of the human race
use it to fortify
foods and forts
strong wills and artificial lungs.
But more than simply on our tongues,
though most of it is in the core
enough remains in the crust
for banded rocks in days of yore
though most now simply turns to rust.
Isn't that ironic?
