Cathreim Thoirdhealbhaigh, or Triumphs of Torlough in English, is a historical account written in the 14th century in Irish by Seán mac Ruaidhrí Mac Craith, the chief historian to the Uí Bhriain dynasty.[1] It depicts the wars between the Irish Uí Bhriain and the English de Clares for control of the Thomond region of Ireland, drawing from contemporary sources for details. Though it has been praised for its accuracy and historical value, it is not a strictly scholarly work: it incorporates verse as well as prose, and includes fantastical elements such as the banshee in the historical events it describes.

The work is of interest to members of the O'Dea Clan because is contains historical references that link the O'Dea with the O'Briens of County Clare.
