English: Táin Bó Cúailnge "the driving-off of cows of Cooley", more usually rendered The Cattle Raid of Cooley or The Táin) is a legendary tale from early Irish literature, often considered an epic, although it is written primarily in prose rather than verse. It tells of a war against Ulster by the Connacht queen Medb and her husband Ailill, who intend to steal the stud bull Donn Cuailnge, opposed only by the teenage Ulster hero Cúchulainn. Traditionally set in the 1st century AD in an essentially pre-Christian heroic age, the Táin is the central text of a group of tales known as the Ulster Cycle. It survives in two main written versions or "recensions" in 12th century manuscripts, the first a compilation largely written in Old Irish, the second a more consistent work in Middle Irish.
