The keeper of a well of wisdom at Cahernarry (or Cahirnarry), Co. Limerick, according to Feis Tighe Chonáin [The Feast at Conán's House]. Bec's three daughters were guarding the well when Fionn and two companions approached, looking for water. One of the daughters accidentally dropped some water from a bowl which fell into Fionn's mouth, giving him wisdom. The Norse scholar E. O. Turville Petre once suggested that the episode reminded him of Odin's gaining of wisdom from the mead of Kvasir; Myth and Religion of the North (London and New York, 1964), 40–1.
