Arcadia (or a frame of reference for enframing references)

From the very title of the play, Arcadia, Stoppard's is clearly a work rich in references that span time in order to question notions of place based simply on geography. As material in Wikipedia on ancient Arcadia points out, "regions of ancient Greece were areas identified by the ancient Greeks as geographical sub-divisions of the Hellenic world. These regions are described in the works of ancient historians and geographers, and in the legends and myths of the ancient Greeks... Due to its remote, mountainous character, Arcadia seems to have been a cultural refuge" ("Ancient Arcadia", Wikipedia). Ancient Arcadia and modern Arcadia occupy similar geographic positions to this day - though, with their longstanding integration into the cultural life of greater Greece, they're less apt to call their neighbors barbarians for not being great with a lyre.
