Sorry nothing to do with "Platonicity" which Taleb strongly criticized. A "greek among Romans", is imo to describe somebody educated, vs a farmer like Cato the old, well versed in refined art vs. propaganda "pompier" political art (to show Power more than beauty or harmony; Romans could only copy Praxiteles), interested in Philosophy more than law. The Circus for the People of Athenes was tragedy by Aeschylus and Sophocles.
