Adam of Bremen, History of the Archbishops of Hamburg-Bremen
Adam was master of schools at the German cathedral of Bremen.

Adhemar of Chabannes, Chronicle
A monk writing in the first third of the eleventh century, Adhemar produced a wide variety of texts ranging across different genres and is particularly famous for his liturgical texts, his use of musical notation, and his famous forgery promoting the idea that St Martial of Limoges was one of the original apostles of Christ. One of his major works was a Chronicle of Frankish history from the origins of the Merovingian dynasty down to 1028, which provides his own take on the history of the early Capetian dynasty.
French: Yves Chauvin and Georges Pon, Adhemar of Chabannes, Chronique (2003).

English: Gearóid Mac Niocaill,, available via CELT (Corpus of Electronic Texts).

The Annals of Ulster
Covering the period 431 to A.D. 1540, the entries in this collection of annals were collated in the fifteenth century, but are of significant value to historians of early medieval Ireland. The annals for our period are predominantly written in Old Irish, with some Latin entries.

Armes Prydein Vawr/The Great Prophecy of Britain
This tenth-century Welsh heroic poem describes an imagined future in which Brittonic peoples ally with Scots, Irish, and vikings together to expel the Anglo-Saxons from Britain. It is thought to have been written in response to the encroaching ambitions and predatory interests of the English kings of Wessex.
English: Rachel Bromwich, Armes Prydein: The Prophecy of Britain, ed. Ivor Williams, From the Book of Taliesin (1972); Michael Livingston, The Battle of Brunanburh: A Casebook (2011).

English: Eric Christiansen, Dudo of St Quentin: History of the Normans (Woodbridge, 1998).

Encomium Emmae Reginae/ The Encomium of Queen Emma
Written by an anonymous monk of Saint Bertin, this remarkable text is written to praise Queen Emma, a Norman first married to the Anglo-Saxon King Aethelred II and then to the Danish King Cnut, who conquered England. It is valuable not only for a highly-coloured view of the Danish conquest, but also for the chaotic politics of England following Cnut’s death, and as a rare example of the perspective of female rule.
English: Alistair Campbell, Encomium Emmae Reginae, with a supplementary introduction by Simon Keynes (1998).

Flodoard of Reims, Annals
Flodoard chronicles the years 919 to 966, focusing on his own church in Reims, thus providing us with one of our only contemporary sources for West Frankish history in this period. He also includes some events taking place in the neighbouring regions of Lotharingia, the German Empire and England.

French: P. Riché and J.-P. Callu, Gerbert d’Aurillac, Correspondance (1993).

Hartvic, Life of King Stephen of Hungary
This biography of the Hungarian saint-king Stephen, (b. 975, r. 997–1038) was the third written but became the ‘official’ version after its commission by King Coloman. Stephen brought missionaries to his kingdom and was in contact with Ottonian luminaries of the era, including Bruno of Querfurt and Odilo of Cluny. Bishop Hartvic’s twelfth-century work provides a window onto Hungarian national history and a perspective of the Ottonian and Salian empires from outside their boundaries.
English: Nora Berend in Thomas Head, Medieval Hagiography: An Anthology (2000). Sections are available online here.

Helgaud de Fleury, Life of Robert the Pious

Hrotsvitha of Gandersheim, The Establishment of the Convent of Gandersheim
An account of the origins of the Ottonian convent at Gandersheim, where Hrotsvitha herself was a canoness.

English: Thomas Head, Medieval Hagiography: an Anthology (2000).
German: Helena Homeyer, Hrotsvitha von Gandersheim (1973).

The passage concerning the Vikings in the Rus’ can be found online:  James E. Montgomery, ‘Ibn Faḍlān and the Rūsiyyah’, Journal of Arabic and Islamic Studies 3 (2000), pp. 1–25.

Ibn Hayyān, al-Muqtabis
Ibn Hayyān’s history of Andalusia is a vital source for the history of Córdoba, written by an important member of the court of the ruler al-Mansūr. Ibn Hayyān wrote in the middle eleventh century and his work only partly survives, but is nevertheless a vitally important source.
Spanish: M. Jesús Viguera and Federico Corriente, Cronica del Califa ‘Abdarraḥmān III an-Nāṣir entre los años 912 y 942 (al-Muqtabis V) (1981).

John of St Arnulf in Metz, The Life of John of Gorze

English: Frank Barlow, The Life of King Edward who Rests at Westminster, 2nd ed. (1992).

The Lives of Queen Mathilda
Two hagiographical lives of Queen Mathilda, which offer valuable information on the Ottonian family and ideas of queenship in tenth-century Germany.
English: Sean Gilsdorf, Queenship and Sanctity (2004).
German: Ph. Jaffé, W. Wattenbach, Das Leben der Königin Mathilde (1891).

Liudprand of Cremona, Book of Retribution, Embassy to Constantinople, Concerning King Otto
A colourful figure, Liudprand’s texts reveal to us much about the Bishop of Cremona’s views of diplomacy, Byzantium, and contemporary politics. While his reliability is very much a topic of debate, his works are of vital importance to both the history of tenth-century Italy and to the Ottonian royal court.
English: Paolo Squatriti, The Complete Works of Liudprand of Cremona (2007).
German: Albert Bauer and Reinhold Rau, Liudprands Werke, in Rudolf Buchner et al., Quellen zur Geschichte der sächsischen Kaiserzeit (1992).

Odilo of Cluny, Epitaph of Adelheid
Structured as an epitaph, designed to console others after a death, this text by Abbot Odilo of Cluny provides us with a stylised account of one of the most powerful women in tenth-century Europe, Empress Adelheid.
English: Sean Gilsdorf, Queenship and Sanctity (2004).
German: H. Hüffer, W. Wattenbach, Das Leben der Kaiserin Adalheid von Odilo von Cluny (1939).

Odo of Cluny, Life of St Gerald of Aurillac
This mid-tenth-century biography takes as its subject a late-ninth-century layman who was secretly tonsured and later became a saint. It is of particular interest because of Gerald’s status as a count: laymen were seldom written about; far from being a cloistered ascetic, Gerald’s biography is full of interactions with political elites.
English: Gerard Sitwell, O.S.B, in Thomas F. X. Noble and Thomas Head, Soldiers of Christ: Saints and Saints Lives from Late Antiquity and the Early Middle Ages (1995).

Odorannus of Sens, Works
The author of texts ranging from monastic origin stories to historical chronicles; from sermons to collections of canon law; and from discussions of musical theory to epitaphs, Odorannus offers us an insight into his intellectual world and concerns as a mid-eleventh-century monk in France.
French: Robert-Henri Bautier and Monique Gilles, Odorannus of Sens, Opera Omnia (1972).

The Quedlinburg Annals

It acts as a particularly important source for the tenth century German Empire, being used by Thietmar of Merseburg as well as several later German annals.
German: E. Winkelmann, Die Jahrbücher von Quedlinburg (1941).

Rather of Verona, Works
Rather’s collection of letters, sermons and treatises illustrate his struggles to navigate the political stage of tenth-century Italy in the service of the German emperor.
English: P. Reid, The Complete Works of Rather of Verona, (1991).

Regino of Prüm, Chronicle
One of the most influential sources of the history of the later Carolingian empire, Regino’s Chronicle looks back at Carolingian politics after the collapse of the empire in 888. Regino not only gives us a detailed account of late ninth-century history, he also provides insights into the rise of the new post-888 kingdoms led by rulers who were no longer Carolingians but instead – as he memorably put it – chosen ‘from their own guts’.
English: Simon MacLean, History and Politics in Late Carolingian and Ottonian Europe: The Chronicle of Regino of Prüm and Adalbert of Magdeburg (2oo9).
German: R. Rau, Quellen zur karolingischen Reichsgeschichte III (1960).

Regino of Prüm, Two Books of Ecclesiastical Discipline
In addition to his Chronicle, Regino also composed a book on ecclesiastical discipline, which would have been used to correct behaviours and practices within different churches. Parts of this work were later included in Burchard of Worms’ Decretum in the early eleventh century.
English: Sarah Hamilton has provided a new translation of Regino’s guide to episcopal visitations on this website.
See also R. Somerville, B. Brasington, Prefaces to Canon Law Books in Latin Christianity. Selected Translations, 500-1245 (1998), pp. 92-9 (partial translation).

Richer of Rheims, Histories
Though based on the writings of Flodoard of Rheims, Richer’s account provides much new material. While trust in Richer’s historical accuracy is relatively low, his anecdotes and narratives are valuable for their perspective and uses of the past in the 990s.
English: Justin Lake, Richer of Saint-Rémi (2011).
French: R. Latouche, Richer, Histoire de France (1937).
German: K. v. D. Osten-Sacken, W. Wattenbach, Richers vier Bücher Geschichte (1941).

Rudolf Glaber, Five Books of Histories
Sometimes dismissed by earlier historians as unreliable, Rudolf’s study of history from 900 to 1044 has more recently been recognised for its value as a source of contemporary history explicitly focusing on the period around the year 1000.
English: John France, Rodulfus Glaber, Opera (1989).
French: M. Arnoux, Radulfus: Histoires (1996).
Italian: A. Fontana, Rodolfo il Glabro. Storie del mille (2001).

Ruotger, Life of St Bruno, Archbishop of Cologne
This hagiography of Bruno, brother of Otto I and archbishop of Cologne, gives us a striking insight into the life of a man who was at once an archbishop and a duke. As such, it has been a fundamental source in discussions of the Ottonian Reichskirchensystem.
German: H. Kallfelz, Lebensbeschreibungen einiger Bischöfe des 10. -12. Jahrhunderts (1973), pp. 179-261.

Skaldic Poetry
Skaldic poetry almost all survives in later Icelandic sagas, but is thought to be reliable because its metre is so complex that scholars believe it could not be misremembered or garbled. During the reign of King Cnut over England, Denmark and Norway, his court became the focal point for the Danish king’s court skaldic composition and patronage in the North Atlantic.
Access to a number of translated skaldic verses is available here, via the Skaldic Poetry of the Scandinavian Middle Ages project. To read translations, click on the ‘edition’ tab on the right hand side of the page and if available is will appear alongside the original Norse.

Synoptic Histories
These texts were all written in the twelfth century in Scandinavia, and have a complex inter-relationship. They are however, some of the only written sources for early medieval Scandinavia, and as such are of great importance.

Thietmar of Merseburg, Chronicle
Thietmar’s chronicle, covering the period from 908–1018, provides readers with one of the most important sources for East Frankish history in the early eleventh century. He also offers views of the kingdoms to the east and Scandinavia. As a Saxon nobleman and Bishop of Merseburg from 1009, Thietmar was well-connected and his information is considered invaluable.
English: David Warner, Ottonian Germany (2001)
German: Werner Trillmich Thietmar von Merseburg. Chronik. (1957).

Widukind of Corvey, Deeds of the Saxons
Written in three books, this history of the Saxons by the learned Corvey monk Widukind takes its readers through Saxon history from the distant past to Widukind’s own time in the middle third of the tenth century, but focuses particularly on the reigns of Henry I and Otto I.

German: Ekkehart Rotter and Bernd Schneidmüller, Die Sachsengeschichte (1981).

Wipo, Deeds of Conrad II

German: Werner Trillmich and Rudolf Buchner, Quellen des 9. und 11. Jahrhunderts zur Geschichte der hamburgischen Kirche und des Reiches (2000).
