Among his pupils were many of the dominant intellectuals of the Carolingian era.

The Anglo-Saxon Chronicle is a collection of annals in Old English, chronicling the history of the Anglo-Saxons. The original manuscript of the Chronicle was created late in the 9th century, probably in Wessex, during the reign of Alfred the Great. Multiple copies were made of that one original and then distributed to monasteries across England, where they were independently updated. In one case, the Chronicle was still being actively updated in 1154.

It is still today a valuable repertory of much curious information in regard to Scandinavian customs and folklore.

De origine actibusque Getarum, commonly abbreviated Getica, written in Late Latin by Jordanes in or shortly after 551 AD, claims to be a summary of a voluminous account by Cassiodorus of the origin and history of the Gothic people, which is now lost. However, the extent to which Jordanes actually used the work of Cassiodorus is unknown. It is significant as the only remaining contemporaneous resource that gives a full story to the origin and history of the Goths, although how close it is to actual history or origin mythology is a matter of dispute.

The Ecclesiastical History of the English People, written by the Venerable Bede in about AD 731, is a history of the Christian Churches in England, and of England generally; its main focus is on the conflict between the pre-Schism Roman Rite and Celtic Christianity. It was originally composed in Latin, and is considered one of the most important original references on Anglo-Saxon history and has played a key role in the development of an English national identity. It is believed to have been completed in 731 when Bede was approximately 59 years old.

Gregory of Tours was a Gallo-Roman historian and Bishop of Tours, which made him a leading prelate of the area that had been previously referred to as Gaul by the Romans. He was born Georgius Florentius and later added the name Gregorius in honour of his maternal great-grandfather. He is the primary contemporary source for Merovingian history. His most notable work was his Decem Libri Historiarum, better known as the Historia Francorum, a title that later chroniclers gave to it, but he is also known for his accounts of the miracles of saints, especially four books of the miracles of Martin of Tours. St. Martin's tomb was a major pilgrimage destination in the 6th century, and St. Gregory's writings had the practical effect of promoting this highly organized devotion.

Paulus Orosius, less often Paul Orosius in English, was a Roman priest, historian and theologian, and a student of Augustine of Hippo. It is possible that he was born in Bracara Augusta, then capital of the Roman province of Gallaecia, which would have been the capital of the Kingdom of the Suebi by his death. Although there are some questions regarding his biography, such as his exact date of birth, it is known that he was a person of some prestige from a cultural point of view, as he had contact with the greatest figures of his time such as Augustine of Hippo and Jerome of Stridon. In order to meet with them Orosius travelled to cities on the southern coast of the Mediterranean Sea, such as Hippo Regius, Alexandria, and Jerusalem.

The History of the Lombards or the History of the Langobards is the chief work by Paul the Deacon, written in the late 8th century. This incomplete history in six books was written after 787 and at any rate no later than 796, maybe at Montecassino.

The Lorsch Bee Blessing is a bee-keeping prayer intended to bring home honey bees in good health to their hives. It is believed to have been written in the 9th century, and was discovered in a manuscript from the monastery in Lorsch, Germany, famous for the Lorsch Codex. Despite being a Christian prayer written in Old High German, it has remarkable similarities to the Anglo-Saxon and apparently pagan "For a Swarm of Bees" magic charm, and may reflect a common pre-Christian Germanic cultural heritage.

The Merseburg charms or Merseburg incantations are two medieval magic spells, charms or incantations, written in Old High German. They are the only known examples of Germanic pagan belief preserved in the language. They were discovered in 1841 by Georg Waitz, who found them in a theological manuscript from Fulda, written in the 9th century, although there remains some speculation about the date of the charms themselves. The manuscript is stored in the library of the cathedral chapter of Merseburg, hence the name.

The Origo Gentis Langobardorum is a short, 7th-century AD Latin account offering a founding myth of the Longobard people. The first part describes the origin and naming of the Lombards, the following text more resembles a king-list, up until the rule of Perctarit (672–688).

The Sermo Lupi ad Anglos is the title given to a homily composed in England between 1010-1016 by Wulfstan II, Archbishop of York, who commonly styled himself Lupus, or 'wolf' after the first element in his name [wulf-stan = 'wolf-stone']. Though the title is Latin, the work itself is written in Old English. The Sermo Lupi is Wulfstan's most well-known work. In it, he blames a lack of moral discipline amongst his fellow English as the source of God's anger against the English, which has taken the shape of thirty years of Viking raids against England. Wulfstan exhorts the English to behave in a manner more pleasing to God, and specifically to live according to the laws of the Church and of the king. The Sermo Lupi is noted for its rhetorical achievements, and is considered to represent the height of Wulfstan's skill as a homilist and rhetor. The text of the Sermo Lupi has been critically edited many times, most recently by Dorothy Bethurum. The work contains one of several mentions of Old English wælcyrian, a term cognate to the Old Norse valkyrjur—valkyries.
