De origine actibusque Getarum (The Origin and Deeds of the Getae [Goths]), commonly abbreviated Getica, written in Late Latin by Jordanes 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 an extended account of the origin and history of the Goths, although to what extent it should be considered history or origin mythology is a matter of dispute. Synopsis of the work The Getica begins with a discussion of a large island named Scandza, which faces the mouth of the Vistula river and had been described by the writers Claudius Ptolemy and Pomponius Mela. Jordanes reports this island to be the original home of many different peoples including the Goths, who have swarmed like bees from there (16-25). Jordanes commences the history of the Goths with the emigration of a Gothic king named Berig with three ships from Scandza to Gothiscandza (25, 94), in the distant past. In the account of Jordanes (or Cassiodorus), Herodotus' Getian demi-god Zalmoxis becomes a king of the Goths (39). Jordanes tells how the Goths sacked "Troy and Ilium" just after they had recovered somewhat from the war with Agamemnon (108). They are also said to have encountered the Egyptian pharaoh Vesosis (47). The less-fictional part of Jordanes' work begins when the Goths encounter Roman military forces in the 3rd century AD. The work concludes with the defeat of the Goths by the Byzantine general Belisarius, which was recent in the time of Jordanes. Jordanes states that he writes to honour those who were victorious over the Goths after a history of 2030 years. Importance and credibility Because the original work of Cassiodorus has not survived, the work of Jordanes is one of the most important sources for the period of the migration of the European tribes, and the Ostrogoths and Visigoths in particular, from the 3rd century AD. Cassiodorus had claimed to have the Gothic "folk songs" — carmina prisca (Latin) — as an important source; recent scholarship regards this as highly questionable. Jordanes stated that Getae are the same as the Goths, on the testimony of Orosius Paulus. In a passage that has become controversial, he identifies
