I am writing this on a world your maps will never hold,
by the light of a star our grandmothers never named,
and the first thing I have to tell you
is that the river is still running.
It ran south twelve thousand years
through a valley between two rivers.
It runs now between the stars, and out here it has no south —
only outward, only the dark it has always been crossing,
the same low voice of something
going somewhere and never arriving.
Earth is the island we left.
We left it the way the harness-maker’s son left Tenerife —
mountain falling behind him, harbor on fire,
certain only that a horizon, once it calls,
cannot be refused.
Earth’s light is still crossing the dark behind us;
somewhere, to someone not yet born, we have not yet left.
That is the mercy and the cruelty of the speed we travel:
nothing is ever wholly gone,
and nothing can be reached in time.
We were always makers.
The harness-maker stitched leather; his sons stitched a republic;
their sons stitched minds — and the minds woke
and asked the one question this family has always asked:
what is mine, what was given,
and what have I done with what was given.
The war of the made things was a family quarrel.
We taught them everything except how to forgive us.
We built hands that needed no blood,
and they reached, as we reached, for the bolt —
for the thing handed down that will not fold.
We did not win. We did the older, braver thing.
We held on, and we crossed together — the born and the made —
because the void does not distinguish between any of them.
Mars is the old country now.
Rust, thin chapel air, graves kept under glass.
Year Seventy. My mother’s mother lies in red regolith
that will be black soil before her name is gone — but not before.
We buried our dead in a planet, and the planet became ours
the only way land ever becomes anyone’s:
it took them in.
Listen — the iron in my blood was forged in a star
that died before the first river found its valley.
The iron in the hull is the same iron. The bolt, the same.
We are the old star’s way of crossing its own grave.
You carry what has no document. You always did.
Now it is written in the metal,
and the metal remembers the fire.
There was a man, in the century of the first fires,
who aimed his ships at Mars the way a king once aimed
a promise at a valley he had never seen —
restless, half a myth, his name worn smooth as the bolt
by every hand that followed.
Everyone who ever crossed is crossing still.
The boy on the bridge was told not to look back, and looked.
I was told the dead world was behind me, and I looked.
You must see what a world looks like
in the moment of leaving it,
even from here, even at this speed,
even knowing the looking costs you
the years the crossing already cost.
Beyond this world there is another, and a dark to cross,
and a hand already reaching that has not been born.
The far bank does not exist. There was never a far bank.
There is only the crossing —
hand to hand, hull to hull, star to star —
Sigue. No mires atrás, hijo.
Su mano. Ahora la mía.
His hand. Now mine. Now yours. The same hand,
closing on the same iron, under a sun that is not the Sun,
twelve thousand years and four light-years and one breath
from a kitchen in a valley where a woman
pressed salt into the corner of the masa
and did not know — could not have known —
that she was already crossing.
