Flodoard of Reims was a Frankish chronicler and priest of the cathedral church of Reims in the West Frankish kingdom during the decades following the dissolution of the Carolingian Empire. His historical writings are major sources for the history of Western Europe, especially France, in the early and mid-tenth century.
Gottschalk of Orbais was a Saxon theologian, monk and poet. Gottschalk was an early advocate for the doctrine of two-fold predestination, an issue that ripped through both Italy and Francia from 848 into the 850s and 860s. Led by his own interpretation of Augustine's teachings on the matter, he claimed the sinfulness of human nature and the need to turn to God with a humility for salvation. He saw himself as a divine vessel calling all of Christianity to repent for decades of Civil War. His attempts of this new Christianisation of Francia ultimately failed, his doctrine was condemned as heresy at the 848 council of Mainz and 849 council of Quierzy. Following his conviction as a heretic Gottschalk remained stubborn to his ideology disobeying the ecclesiastical hierarchy, making him an "actual heretic in the flesh", for this disobedience Gottschalk was placed in monastic confinement; however the shockwaves his ideology sent around Western Christendom refused to stop reverberating, Gottschalk managed to win over more followers and the threat remained up until his death in 868.

The Decretum Gratiani, also known as the Concordia discordantium canonum or Concordantia discordantium canonum or simply as the Decretum, is a collection of canon law compiled and written in the 12th century as a legal textbook by the jurist known as Gratian. It forms the first part of the collection of six legal texts, which together became known as the Corpus Juris Canonici. It was used as the main source of law by canonists of the Roman Catholic Church until the Decretals, promulgated by Pope Gregory IX in 1234, obtained legal force, after which it was the cornerstone of the Corpus Juris Canonici, in force until 1917.
A capitulary was a series of legislative or administrative acts emanating from the Frankish court of the Merovingian and Carolingian dynasties, especially that of Charlemagne, the first emperor of the Romans in the west since the collapse of the Western Roman Empire in the late 5th century. They were so called because they were formally divided into sections called capitula.
The Chronicle of Fredegar is the conventional title used for a 7th-century Frankish chronicle that was probably written in Burgundy. The author is unknown and the attribution to Fredegar dates only from the 16th century.
Theodulf of Orléans was a writer, poet and the Bishop of Orléans during the reign of Charlemagne and Louis the Pious. He was a key member of the Carolingian Renaissance and an important figure during the many reforms of the church under Charlemagne, as well as almost certainly the author of the Libri Carolini, "much the fullest statement of the Western attitude to representational art that has been left to us by the Middle Ages". He is mainly remembered for this and the survival of the private oratory or chapel made for his villa at Germigny-des-Prés, with a mosaic probably from about 806. In Bible manuscripts produced under his influence, the Book of Baruch and the Letter of Jeremiah became part of the Western (Vulgate) Bible canon.

The Libellus responsionum is a papal letter written in 601 by Pope Gregory I to Augustine of Canterbury in response to several of Augustine's questions regarding the nascent church in Anglo-Saxon England. The Libellus was reproduced in its entirety by Bede in his Historia ecclesiastica gentis Anglorum, whence it was transmitted widely in the Middle Ages, and where it is still most often encountered by students and historians today. Before it was ever transmitted in Bede's Historia, however, the Libellus circulated as part of several different early medieval canon law collections, often in the company of texts of a penitential nature.
Jus antiquum is a period in the legal history of the Catholic Church, spanning from the beginning of the church to the Decretum of Gratian, i.e. from A.D. 33 to around 1150. In the first 10 centuries of the church, there was a great proliferation of canonical collections, mostly assembled by private individuals and not by church authority as such.
The Paenitentiale Theodori is an early medieval penitential handbook based on the judgements of Archbishop Theodore of Canterbury. It exists in multiple versions, the fullest and historically most important of which is the U or Discipulus Umbrensium version, composed (probably) in Northumbria within approximately a decade or two after Theodore's death. Other early though far less popular versions are those known today as the Capitula Dacheriana, the Canones Gregorii, the Canones Basilienses, and the Canones Cottoniani, all of which were compiled before the Paenitentiale Umbrense probably in either Ireland and/or England during or shortly after Theodore's lifetime.
The Collectio canonum Quesnelliana is a vast collection of canonical and doctrinal documents prepared (probably) in Rome sometime between 494 and (probably) 610.

The standard edition used today is that prepared by Girolamo and Pietro Ballerini in 1757.
