His writings survive in around twenty manuscripts or fragments, dating from the eighth to the eleventh century. The three principal manuscripts (Paris, Bibliothèque nationale Latinus 13026; Amiens, Bibliothèque municipale, 426; and Naples, Biblioteca Nazionale IV.A.34) on which modern editions have been based were all written in early ninth-century France. In most manuscripts of Virgil also contain other grammatical and schoolroom texts. As a rule, the "Epitomae" travelled separately from the "Epistolae", which are much more poorly represented in the surviving manuscripts: just one manuscript contains the entire text (Naples, Biblioteca Nazionale IV.A.34), and comparison with other fragments suggests its testimony may not always be trustworthy.
