Cycles of the Kings
The Cycles of the Kings or Kings' Cycles, sometimes called the Historical Cycle, are a body of Old and Middle Irish literature. They comprise legends about historical and semi-historical kings of Ireland (such as Buile Shuibhne, "The Madness of King Suibhne"), stories about the origins of dynasties and peoples (such as The Expulsion of the Déisi), accounts of significant battles (such as Battle of Mag Mucrama), as well as anecdotes that explain rites and customs.
