Anonymus Valesianus

''Anonymus Valesianus'' (or ''Excerpta Valesiana'') is the conventional title of a compilation of two fragmentary vulgar Latin chronicles, named for its modern editor, Henricus Valesius, who published the texts for the first time in 1636, together with his first printed edition of the ''Res Gestae'' of Ammianus Marcellinus. The two fragments are not related, one being from the fourth century and the other from the sixth. The only connection between the two fragments is their presence in the same manuscript and their history of being edited together. When Henricus' brother re-edited the ''Anonymus'' in an edition of Ammianus Marcellinus in 1681, it was the first time that the two excerpts were clearly separated.

The work of the Anonymus Valesianus is a debated issue of historiography for more than one hundred years, all the more so as both the identity of the authors and the circumstances of the compilation of the work are obscure. Provided by Wikipedia
