From Wikipedia: "Baile Chuind Chétchathaig ("The Vision of Conn of the Hundred Battles") is an Old Irish list of Kings of Tara or High Kings of Ireland which survives in two 16th-century manuscripts, 23 N 10 and Egerton 88. It is the earliest such king-list known, probably dating from around 700 AD. The later Baile In Scáil is closely related."
