Why is it called Cervantes?

This is a short impromptu video I recorded when I was walking through the sculpture garden at the Albuquerque Museum.  As I approached it from the south side, it appeared to me to be the head of a pig.  As I move around to the north side view, I realized it was a human head, and that of a male, which appeared to me to be a conquistador!  This made perfect sense to me, given where I am, both in time and place;  a decapitation (symbolic, of course) of one of those notorious Spaniards who had travelled to this 'new world' and had their way with the resources offered by the people and the land.   I went on to conjecture that the head could be that of Herman Cortes.  But when I read that the title of the piece was Cervantes, I thought, Why is it called Cervantes?  Actually, I protested, Why Cervantes?  Was this done in the spirit of Cervantes, as some grand gesture of irony, and was, therefore, a postmodern work as opposed to the decolonial inspired piece I imagined it to be?  But it couldn't be ironic, or where was the irony?  The lines are too subtle and the whole head too anatomically correct. So where the irony?  Shouldn't it be ironic?  I want it to be ironic if it's called Cervantes!  Otherwise, I declare the alternative title to be "Cabeza de Vaca."

Alvar Nunez Cabeza de Vaca (1488-1558) was a conquistador (Spanish ‘explorer’).  During the eight years of traveling across the US Southwest, he became a slave trader but also, paradoxically, a shaman to various Native American tribe before reconnecting with Spanish colonial forces in Mexico in 1536.  After returning to Spain in 1537, he wrote an account, first published in 1542 as La Relacion (‘The Account’).  [borrowed from Wikipedia)
