De origine actibusque Getarum (
"The Origin and Deeds of the Getae/Goths"), or the
Getica, written in
Late Latin by
Jordanes (or
Iordanes/Jornandes) 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 the full story of the origin and history of the
Goths. Another aspect of this work is its information about the early history and the customs of
Slavs.
