The very first mentions of the name of Caen are found in different acts of the dukes of Normandy: "Cadon" 1021/1025, "Cadumus" 1025, "Cathim" 1026/1027. Year 1070 of the Parker manuscript of the "Anglo-Saxon Chronicle" refers to Caen as "Kadum", and year 1086 of the Laud manuscript gives the name as "Caþum". Despite a lack of sources as to the origin of the settlements, the name Caen would seem to be of Gaulish origin, from the words "catu-", referring to military activities and "magos", field, hence meaning "manoeuvre field" or "battlefield". In Layamon's "Brut", the poet asserts that King Arthur named the city in memory of Sir Kay.
