Like many figures of the time period, few of the historical facts about Pepin have been fixed with certainty. Most of what is known about him comes from just a handful of early medieval annals and histories. Understanding the context of these sources, as well as their built-in biases and shortcomings, is essential to understanding Pepin. One of the earliest, most contemporary descriptions of Pepin is found in the
Gesta Episcoporum Mettensium, an ecclesiastical history of the
see of Metz written by Paul the Deacon around 785. Paul often digresses into broader themes of Carolingian history, and some historians (like Walter Goffart) read a great deal about the plight of Pepin into the supposedly allegorical histories that Paul provides of Charlemagne's ancestors. Paul also touches on Pepin directly, at least occasionally: Historical appraisal of the
Gesta has varied widely over time, however, and many historians see it as more of a "literary curiosity" with only an incidental or inadvertent historical value. Even Goffart admits that historians value much of Paul's work only as a mere "repository of legends." Another nearly contemporary source for the life of Pepin are the
Lorsch Annals, a series of historical entries compiled by Frankish monks during the life of Charlemagne. The annals provide one of the best early accounts of Pepin's revolt: The
Royal Frankish Annals provide another foundational annalistic source for the study of Pepin. Although they were probably compiled in Charlemagne's court, a later writer revised them after the emperor's death, which might impact the way in which the annals cover Pepin. Einhard, a scholar at Charlemagne's court and one of the king's most important early biographers, provides only a glancing mention of Pepin. Initially, he makes no mention of Pepin or Himilitrude in his list of Charlemagne's legitimate offspring and spouses in his
Vita Karoli Magni: But Einhard knew that Pepin was Charlemagne's son—although he does not mention that Pepin was the first born. Only a few pages later, Einhard acknowledges Pepin's birth, saying, "By one of his concubines he had a son, handsome in face, but hunchbacked, named Pepin, whom I omitted to mention in the list of his children." Apparently Pepin was already in a sort of historical exile by the time of Einhard's writing: he is not portrayed as part of the legitimate lineage and does not enjoy the place of honor enjoyed by Charlemagne's other offspring. This is explained by Einhard's subsequent account of Pepin's revolt. Pepin feigned illness as he plotted with "certain leading Franks" to overthrow his father. When the plot was discovered, Einhard writes that Pepin was tonsured and sent directly to the monastery of Prüm. In his paper "Pipinus Rex" historian Carl Hammer points out the disparate attention Einhard gives to Pepin's revolt, arguing, "he gives it priority over his account of the evidently more widespread and possibly more dangerous rebellion of 785/6." Hammer also points out that Einhard describes Pepin as a "hapless pawn of the real conspirators" and so hopes to maintain the cohesion of the family unit in his portrayal of Charlemagne and his offspring. Hammer points out that no historian we have record of prior to Einhard called Pepin "the Hunchback"—Presumably, this slander was another aspect of Einhard's attempt to spare the family." A third and differing account of Pepin's life comes from Notker the Stammerer, a
Benedictine monk writing during the reign of
Charles the Fat, the great-grandson of Charlemagne. Notker's account, referred to by modern scholars as the
Gesta Caroli Magni ("The Deeds of Charles the Great") or
De Carolo Magno ("Concerning Charles the Great") provides much more detail about Pepin's plot than earlier sources, although some of the story seems heavily inspired by classical sources. According to Notker, Pepin and his co-conspirators meet in the church of St. Peter in Regensburg to discuss their plot, where a cleric hiding under the altar overhears them. After the deacon reveals the conspiracy to Charlemagne, the plotters are captured, and Pepin is "cruelly scourged" and banished to a poor monastery—Notker claims that it was the monastery of St. Gall, although Pepin was almost certainly sent to the monastery of Prüm. Notker, however, adds another element to the story, possibly borrowed from the Roman historian
Livy's account of
Tarquin's poppies. Some time later, when faced with another revolt, Charlemagne sends messengers to Pepin to ask his advice. The king's men find Pepin weeding nestles in the garden, where he refuses to offer Charlemagne any advice, saying "I will send him no message except—what I am doing! I am digging up the useless weeds in order that the valuable vegetables may be able to develop more freely." When the messengers relate the story back to Charlemagne, he manages to "divine the real meaning of the words" and puts the rebellious nobles to death. As a reward for his good counsel, Charlemagne allows Pepin to choose "the manner of life that most pleased him" and Pepin asks to move to the monastery of Prüm. The
Poeta Saxo, an anonymous Saxon poet who composed the
Annales de gestis Caroli magni imperatoris libri quinque ("Annals of the Deeds of Emperor Charlemagne in Five Books") near the end of the 9th century, relies heavily on classical models and existing sources like Einhard and the Royal Frankish Annals. Generally, he offers an interesting literary restatement of the older vitae and annals, but little new history. ==In fiction and popular culture==
