Follow-up to Damian's talk

I'd like to pursue a bit further the question I asked of Damian after his talk today. Laurie echoes this question, to some degree, on her blog when she asks about Damian's inclusion or exclusion of Greco-Roman theories of rhetoric.

My question today was really about the parallels as well as divergences that Damian sees between his work and that of scholars who are doing revisionist histories of ancient rhetorics such as Carol Lipson and others in her edited collection _Rhetoric Before and Beyond the Greeks_ or Kermit Campbell (his recent article) or Lu on Ancient Chinese Rhetorics. Although Damian is not dealing with a BCE time period, I do wonder about fruitful links that could be made between MesoAmerican cultures and that of African cultures, Middle Eastern cultures, and Asian cultures.
