I study something as equally esoteric, and I'd like to comment that if you do manage to find a location to study your interests, you might consider career paths outside of the traditional, academic. Indeed, it might be the wisest course of action.
I'm planning to work in libraries. No department would ever want someone who specializes in what I do. Well, it's highly unlikely, at least. Job prospects are generally based on departmental needs which are in turn based on archetypal historians.
