The Historia Regum ("History of the Kings") is a historical compilation attributed to Symeon of Durham, which presents material going from the death of Bede until 1129.
It survives only in one manuscript compiled in Yorkshire in the mid-to-late 12th century, though the material is earlier.
[7] The full text survives in one manuscript, Cambridge, Corpus Christi College, MS 139, at folios 51v–129v, written down in the late 12th century.
[8] An abbreviated copy is also found in Paris, Bibliothèque nationale de France, MS nouv.
[8] Besides not being an original historical work, reasons of internal evidence make it highly unlikely that the Historia Regum was written by the same author as the Libellus de exordio,[10] which is generally accepted to have been authored by Symeon.
