Matthew Barney: C/D?

Not sure I see the connection to the Field Emblem, though you may be on to something with the materials. Cremaster used Vaseline/plastic/beeswax (very explicitly in Cremaster 2), and Fundament moves over to gold leaf and metals, roughly following Benglis's trajectory. And I should maybe also add that Fundament features many gold-leaf phalluses and turds.

The general "lozenge" shape with a horizontal division at the center- it's not as apparent on all of Benglis's beeswax paintings but there's a line where she started brushing outward vertically.

I'll have to check out River of Fundament if I can.
