Táin Bó Cúailnge, frequently referred to as the Táin, is one of the most important works of medieval Irish literature and has been called the national epic of Ireland. This new, judiciously abridged translation of the Táin renders the text in an approachable, colloquial style that nevertheless maintains enough accuracy to support close reading. This edition also contextualizes the Táin itself with numerous selections from the rest of the so-called Ulster Cycle—the related body of legends about the characters of the Táin, including accounts of their origins and their deaths. Also included are a full introduction; extensive footnotes, drawing on the most recent scholarship on the Táin, that provide clarifications, explanations, and background information; four maps showing the sites of major events in the epic; and a series of character trees to help readers keep track of the Táin’s large cast of characters and their often complex interrelationships, among other valuable resources.
