A collection of seven manuscripts written in Anglo‐Saxon (Old English) that together provide a history of England from the beginning of the conversion to Christianity up to 1154. The major text (known as the Parker Chronicle) appears to have been written by one clerk until 891. Most of the copies end in the 11th century; after 1079 only the Peterborough Chronicle continued, breaking off abruptly with an unfinished entry for 1154. The Chronicle probably originated as notes inserted in the tables used by the Christian Church when calculating the date of Easter.
