Thanks for commenting, Dick. Yesterday I was reading some of the work that Orr quotes, Genette’s Paratexts, and was interested to learn that this practice of applying epigraphs from other authors to the front of books, then chapters, then later still poems, is really only something that’s taken off since the Romantic period. But to me it’s just the latest manifestation of the basic call-and-reponse or epistolary approach to poetry community-building that goes back to ancient times in the West, and flourished in other poetry-centric civilizations as well.
