Hello! I´m currently preparing for a celtic studies minor (next to archaeology) in university and would like to explore some primary sources beforehand, because that´s what I enjoy doing and I´ve got an okay amount of time right now. I already know about the Book of Invasions, the Ulster cycle and the Fenian cycle. Does anyone have other recommendations about literature that you think is important and that I should maybe take a look at as well?
