Presently, Latin Stack Exchange is the place to go for questions regarding the Graeco-Roman world. According to this Meta answer, Latin SE also accepts questions on Ancient Greek. My suggestion thus is two-fold:
- Latin SE should be rebranded to Classics SE, Classics defined as the subjects studied by any Classics scholar, id est the Graeco-Roman world and their relations to the outside world.
- The new SE should also redefine itself to be not just a source for the two languages (Ancient Greek and Latin), but also for the cultures of this temporally and spatially vast area.
To better facilitate the structure of such a rebranded site, some new tags would be necessary;
mediaeval-latin immediately springs to mind, but perhaps also tags relating to other cultures with which the Graeco-Roman world interacted. Should one include Coptic? What about the languages of the conquered peoples? Etruscan is a natural subject, as well as Oscan, but also the languages of other conquered areas, such as those subjugated be the campaigns of Caesar. What about specialised fields within Classics, such as epigraphy?
Obviously, such a rebranding would immediately cause one major issue: Where would one draw the line for which questions are within the sphere of interest of such a site. A well-thought-out definition of what Classics is and which subject-matter falls within its sphere would be necessary. But first and foremost, one would need to discuss whether this is in fact needed.
Please do note that I have included the tag
