When I think of Irish literature the names that come to mind are the likes of John Banville, William Trevor, and Colm T?ib?n. But they all write in English. As did, going further back, James Joyce.
I guess my first question is are there writers out there publishing works in Irish? And anothers would be are there classic works of Irish literature written in Irish? If so, what are they?
I would like to add Joseph Campbell to your list of Irish writers... James Joyce has written works in Irish and so has Joseph Cambell. Ciaran Carson also has written in Irish. In fact if I remember correctly they all have, but have since been translated into English as well.
As for classic works, I know that T?in B? C?ailnge was published in Irish. I had to read it in the Irish when I took an Irish Literature class.
