Diving into the wreck

I first read this in, what, 1976 or so?

I am here, the mermaid whose dark hair
streams black, the merman in his armored body
We circle silently
about the wreck
we dive into the hold. ...
We are, I am, you are
by cowardice or courage
the one who find our way
back to the scene
carrying a knife, a camera
a book of myths
in which
our names do not appear.

Rest in peace, Adrienne Rich.
