 He also mentions that the Goths had previously defeated the Burgundians.Ammianus Marcellinus, on the other hand, claimed that the Burgundians were descended from Romans.The Roman sources do not speak of any specific migration from Poland by the Burgundians (although other Vandalic peoples are more clearly mentioned as having moved west in this period), and so there have historically been some doubts about the link between the eastern and western Burgundians.
