animal man is a prince. As from alabaster
a lucency animates him from heel to forehead.
Then his shadows are deep and not gray.”

I sing. The ache
up from heel to knee
of the weights
gives to the song its
ground bass.”

that the stream is trampled,
the sand on the stream-bank
still holds the print of your foot:
the heel is cut deep.”
