Goddess BRIGHID Celtic Goddess Brighid Origins of Brighid: In Irish mythological cycles, Brighid (or Brighit), whose name is derived from the Celtic brig or "exalted one", is the daughter of the Dagda, and therefore one of the Tuatha de Dannan. Her two sisters were also called Brighid, and were associated with healing and crafts. The three Brighids were typically treated as three aspects of a single deity, making her a classic Celtic triple goddess.
