Cessair

Cessair or Cesair (spelled Ceasair in modern Irish, meaning 'sorrow, affliction') is a character from a medieval Irish origin myth, best known from the 11th-century chronicle text Lebor Gabála Érenn. According to the Lebor Gabála, she was the leader of the first inhabitants of Ireland, arriving before the Biblical flood. The tale may have been an attempt to Christianize an earlier pagan myth.
