Jordanes

Jordanes (; Greek: Ιορδάνης), also written as Jordanis or Jornandes, was a 6th-century Eastern Roman bureaucrat,}} widely believed to be of Gothic descent, who became a historian later in life.

He wrote two works, one on Roman history (''Romana'') and the other on the Goths (''Getica''). The latter, along with Isidore of Seville's ''Historia Gothorum'', is one of only two extant ancient works dealing with the early history of the Goths. Other writers, such as Procopius, wrote works on the later history of the Goths. ''Getica'' has been the object of much critical review. Jordanes wrote in Late Latin rather than the classical Ciceronian Latin. According to his own introduction, he had only three days to review what Cassiodorus had written and so he must also have relied on his own knowledge. Provided by Wikipedia
