I know he was buried in Gela, on the isle of Sicily, and that we have the transcript of his epitaph, but does his tombstone still exist or is his final resting spot known to any more specific degree than that? Even just a general side of town or ancient graveyard stemming from that era?
We don't have Aeschylus' grave marker, or know where it is other than the ancient testimonials that it was in Gela. Our knowledge of the epitaph comes from comments by later authors: Athenaeus, Pausanias, probably a couple of others I'm not remembering off the top of my head. The text itself is quoted in the Palatine Anthology, 7.39
