I've noticed a few cases of locations that are referenced with regard to a real location but in a mythical context, for example: Aeolia, the floating island occupied by Aelous, keeper of the winds, is likely a mythical addition to the Aeolian islands. A similar example would be the relationship between Hades and Tartarus, in which the former has sources supporting a geographic location for the entrance. It would therefore be tempting to associate it with Tartarus, but Tartarus exists purely in the mythical context. Greg is looking at a way to associate cases like this where it is a mythical overlay transposed on a real geographic location.
