The origin of the tribe's name has not been precisely established. Probably, it comes from the Indo-European word weise (wise), just as the name of the Ostrogoths can take roots from the Indo-European word austr (brilliant) [2] . However, the Austrian historian Gerwig Wolfram in his book History of the Goths [3] writes that Vesi in the Goths language meant "respectable", "noble". While Ostrogoth meant "Goths of the rising sun," that is, Eastern Goths.
The first mention of the division of the Goths appears around 270 during the reign of Emperor Claudius II . Then, around 291 , Mamertinus, in his Panegyric in honor of Emperor Maximian, mentions the “Tervingi, part of the Gothorum tribe” [4] ( lat. Tervingi pars alia Gothorum ), who allied with the typhals to attack the Vandals and Gepids . Tervingi , that is, "people of the forests" - an early name for the Visigoths (compare with the early name of the Ostrogoths - Grevtungs , "inhabitants of the steppes and rough sands") [5] .
These tribal names persisted until about the beginning of the 5th century , then after the resettlement of a part of the Gothic tribes beyond the Danube to the territory of the Roman Empire and their mixing, the sources use the generalized ethnonym Goths . By the beginning of the 6th century, the two main branches of the Goths began to be mentioned in historical sources as Vesygotes and Ostrogoths . At the beginning of the 6th century, Cassiodorus , the author of a voluminous "History of the Goths", which later in his work " On the Origin and Deeds of the Getae " was transposed and shortened by Jordan, rethought these names and introduced new ones, conditioned by geography - "Eastern Goths" and "Western Goths". These new names reflected the actual state of affairs - during the time of Cassiodorus, the Visigoths controlled most of the Iberian Peninsula and Gaul , and the Ostrogoths ruled the Apennine Peninsula .
