Gesta Normannorum Ducum

Gesta Normannorum Ducum (Deeds of the Norman Dukes) is a chronicle originally created by the monk William of Jumièges just before 1060.

In later times, Orderic Vitalis (d. c. 1142) and Robert of Torigni (d. 1186), extended the volumes to include history up until Henry I.

[a][2] During the twelfth century there were interpolations and additions, first by Orderic Vitalis, then by Robert of Torigni, who added an entire book on Henry I of England.

[1] Jules Lair undertook a modern translation, but the final work was interrupted by his death.

[5] The original version had ended with the Harrying of the North by the Conqueror in 1070, but a passage mentioning Robert Curthose as duke appears to be a revision sometime after 1087.
