Gutentag,
I'm not sure if this has been discussed yet...but I've been pondering the etymology and significance of Patera Quetzal's name for a while. Could it have something to do with Quetzalcoatl? Perhaps some ties with the Aztecs, since they were involved in bloody rituals (the inhumi connection?)? I know Wolfe is familiar with American mythologies("Native American" would seem too inclusive, I think), besides every other classical mythology out there.
An asimi to whomever can piece this together.
