Longinus' On the Sublime presents itself as a response to the work of the Augustan critic Caecilius of Caleacte. Recent attempts to reconstruct Longinus' intellectual context have largely ignored the works of Dionysius of Halicarnassus, Caecilius' contemporary colleague . This article investigates the concept of hupsos and its religious aspects in Longinus and Dionysius, and reveals a remarkable continuity between the discourse of both authors. Dionysius' works inform us about an Augustan debate on Plato and the sublime, and thereby provide (...) us with an important context for Longinus' treatise. (shrink)
