[Ir., hard head (?), cat-head (?)].
According to the Lebor Gabála [Book of Invasions], when the Aithech-Túatha [plebeian races] overthrow the Milesians they set Cairbre Cinn-Chait to rule over them, and he is sometimes therefore referred to as a usurper. During his reign there is only one grain on each stalk of wheat and one acorn on each oak, the rivers are empty of fish, and the cattle milkless, as nature refuses to condone his wrongful succession. None the less, he is an ancestor of the Érainn. After Cairbre's death his son Morann, who could have succeeded him, returns Ireland to the Milesians.
