Cessair or
Cesair (spelt
Ceasair in modern Irish; anglicized
Kesair) is a character from the
Lebor Gabála Érenn, a medieval Christian pseudo-history of Ireland. According to the
Lebor Gabála, she was the leader of the first inhabitants of
Ireland, before the
Biblical Flood. The tale may be an attempt to
Christianize an earlier pagan myth, but may alternatively be the product of post-conversion
pseudohistory.
