We all have high cultures, in some cases like in IReland its highlighted by history and an obvious state of cultural diglossia.
I understand what you mean by high culture. Let me clarify my question: what is the Irish "High Culture" you're talking about that is different from traditional Irish culture (which I take to mean pre-Christian pagan worship and those myriad traditions)? Perhaps I am just dense today, but I'm not sure I'm following what you mentioned here. What in history highlights the high culture? Unless you're talking about the years of British rule?
