Pablo Garcia, a prof at Carnegie Mellon, beat me to the punch. Here an essay on Pliny the Elder’s telling the story of Butades of Corinth and the fabled origin of painting. I remembered the Schinkel painting from an art history course, googled it and ran smack into all the work I now don’t have to do courtesy of the the good professor. Thanks! Was going to write a load on it but he’s much more of a scholar than I. Good read.
More generally, Garcia says projection is a “technique and conceptual framework” and we do well to heed this! I’ll be cherry picking his site for your reading pleasure so as to get to the relevant parts for us.
