Symeon was author of two historical works which are particularly valuable for northern affairs, the
Libellus de Exordio atque Procursu istius, hoc est Dunelmensis, Ecclesie (
The Little Book on the Origins and Progress of this Church, that is of Durham) and a historical compilation
Historia regum Anglorum et Dacorum. The
Libellus de Exordio, a history of the community of Durham (originally settled at
Lindisfarne) from its inception to the year 1096, is by far his most important work. Composed between 1104 and 1107, Symeon's task (imposed on him by his monastic superiors) was to demonstrate the continuity of Durham's history despite the notable disruptions the community weathered during the
Viking invasions and even more recently in the
Norman Conquest. Symeon sought furthermore to justify William of Saint-Calais's expulsion of Durham's clerical community in 1083, in order to replace it with a group of
Benedictine monks drawn from Wearmouth and Jarrow. Like earlier Durham writers, Symeon finds historical continuity between the major phases of the community's development in the constant presence of their patron,
Saint Cuthbert. The
miracles worked in Cuthbert's name during the late Anglo-Saxon period were particularly flamboyant, and the
Libellus contains engaging accounts of some of these, including the miracle of the three waves (when Cuthbert turned a portion of the Irish Sea into blood in order to prevent his followers from taking his relics out of England, see
Libellus ii.11), the foundation of Durham (when Cuthbert's body, being moved across England on a cart, refused to be moved, signalling his desire to remain at Durham, see
Libellus iii.1), and several picturesque deaths visited upon the enemies of Cuthbert's devotees. Several versions of the
Libellus survive from the Middle Ages. Symeon's own revised copy can be found in Durham, University Library, Cosin V.II.6. It is this text which has been most often published. The Durham manuscript also contains two anonymous continuations of Symeon's work. The first carries the history from 1096 to the death of
Ranulf Flambard (1129); the second extends from 1133 to 1144. A Cambridge manuscript (
Cambridge University Library, Ff. i.27) contains a third continuation covering the years 1145-1154. Another
manuscript (London,
British Library,
Cotton Faustina A.V) seems to represent the text of the
Libellus before the revisions found in the Durham manuscript. A full list of manuscripts can be found on the
Libellus de Exordio page. About 1129 Symeon undertook to write a
Historia regum Anglorum et Dacorum. This begins at the point where the
Ecclesiastical History of
Bede ends. Up to 957 Simeon merely copies some old Durham annals, not otherwise preserved, which are of value for northern history; from that point to 1119 he copies
John of Worcester with certain interpolations. The section dealing with the years 1119-1129 is, however, an independent and practically contemporaneous narrative. Symeon writes, for his time, with ease and perspicuity; but his chief merit is that of a diligent collector and
copyist. Symeon also wrote brief biographies of the
archbishops of York and a letter on the errors of
Origen. Other writings have been attributed to his pen, but on no good authority. They are printed in the
Historiae Anglicanae Scriptores Decem of
Roger Twysden (1652). The most complete modern edition is that of
Thomas Arnold (
Rolls series, 2 vols., 1882–1885). For the
Libellus, now see Rollason's 2000 edition. The value of the
Old Northumbrian Annals, which Symeon used for the
Historia regum, has been discussed by John Hodgson-Hinde in the preface to his
Symeonis Dunelmensis opera, vol. i. pp. xiv. ff. (1868); by R. Pauli in
Forschungen zur deutschen Geschichte, xii. pp. 137 sqq. (Göttingen, 1872); and by
William Stubbs in the introduction to
Roger of Hoveden, vol. i. p. x. ("Rolls" series). ==Citations==
