Bird-headed shaman

I suppose I should not be surprised to find that Clayton Eshleman has been as taken with the bird-headed man as I have been - synchronicity. I did not realize until today that he has written about the Lascaux scene somewhere else. From Hybrid Hierophanies (2016):

Theseus, a tiny male spider, enters a tri-level construction:
look down through the poem, you can see the labyrinth.
Look down through the labyrinth, you can see the spider-centered web.

                                                             Coatlicue
              Sub-incision                Bud Powell
                              César Vallejo
                                          The bird-headed shaman

These nouns are also nodes in a constellation called
Clayton’s Tjurunga. The struts are threads
in a web. There is life blood flowing through
these threads. Coatlicue flows into Bud Powell,
César Vallejo into sub-incision.

                         The bird-headed shaman
is slanted under a disemboweled bison.
His erection tells me he is in flight. He drops
his bird-headed stick as he penetrates
     bison paradise.

The red sandstone hand lamp
abandoned below this scene
is engraved with vulvate chevrons—did it once flame
     from a primal sub-incision?

This is the oldest part of this tjurunga, its grip.
