The story is told that, in the 6th century, the poet Senchán Torpéist gathered the poets of Ireland together to see if any of them knew the story of the Táin Bó Cúailnge, but they all only knew parts of it.
His most important work was Imtheacht na Tromdhaimhe, or, The proceedings of the great Bardic Institution, which relates how Senchán Torpéist recovered the Táin Bó Cúailnge, one of the most famous tales of the Irish bards.
