Fer Corb ("chariot man"), son of Mug Corb, was, according to medieval Irish legend and historical tradition, a High King of Ireland. He came to power after killing his predecessor, and his father's killer, Irereo, in Ulster. He ruled for eleven years, until he was killed by Irereo's son Connla Cáem. The Lebor Gabála ÃÂrenn synchronises his reign with that of Ptolemy IV Philopator of Egypt (221âÂÂ205 BC). The chronology of Geoffrey Keating's Foras Feasa ar ÃÂirinn dates his reign to 330âÂÂ319 BC, the Annals of the Four Masters to 474âÂÂ463 BC.
