Cú Roí

Cú Roí (Cú Ruí, Cú Raoi) mac Dáire is a king of Munster in the Ulster Cycle of Irish mythology. He is usually portrayed as a warrior with superhuman abilities and a master of disguise possessed of magical powers. His name probably means "hound of the plain/field", or more specifically, "hound of the battlefield". He is the son of Dáire mac Dedad (or Dáire Doimthech), and thus belongs to the Clanna Dedad. However, T. F. O'Rahilly believed this to be artificial, stating that "Cú Roí and Dáire are ultimately one and the same".
