Description
Táin Bó Cúailnge — “The Cattle Raid of Cooley” — is the central epic of Ireland’s Ulster Cycle and the great heroic saga of Cú Chulainn. Rooted in pre‑Christian oral tradition, the story was first written down in Old Irish and survives most fully in the 12th‑century Book of Leinster, with earlier fragments in Lebor na hUidre.
The epic recounts Queen Medb’s invasion of Ulster to seize the prized Brown Bull of Cooley, opposed single‑handedly by the young warrior Cú Chulainn. The tale blends myth, battle poetry, supernatural encounters, geasa (taboos), and tragic prophecy, forming one of the oldest heroic narratives in Western Europe.
Its medieval manuscript tradition makes The Táin both a literary treasure and a cultural cornerstone of Irish identity.
