 The Thervingi lived between the Danube and the Carpathians west of the Dniester River; the Greuthungi, and possibly other groups, lived east of the Dniester River.Jordanes, a mid 6th-century historian, describes a large Greuthung kingdom in the late 4th century, but Ammianus Marcellinus, a late 4th-century historian, does not record this.Many modern historians, including Peter Heather and Michael Kulikowski, doubt that it was ever particularly extensive (and suggest one or more smaller kingdoms).
