Bucolics [LIX]

when I see the shadow of the hawk
but not the hawk itself do you know
what it feels like Boss a stone a stone
set on my chest it weighs me down
it's stronger than the horse's strain
against the plowlines Boss it's like
the river after rain I can't
hold back the pull the pull that makes
me like its heft I even like
the shadow's tiny yoke O Boss
I feel its curve around my neck
I see a flap of wings so black
it binds me to the furrows Boss
a shadow smarter than the sting
of a switch though it is lighter than
a feather though it is thinner than
a leaf that shadow stone is one
of many wonders Boss for all
the world it makes me think of you
you heavy thing you never move
