I once saw two snakes,
northern racers,
hurrying through the woods,
their bodies
like two black whips
lifting and dashing forward;
in perfect concert
they held their heads high
and swam forward
on their sleek bellies;
under the trees,
through vines, branches,
over stones,
through fields of flowers,
they traveled
like a matched team
like a dance
like a love affair.
– Mary Oliver
