Further scholarship in the 20th century added more name and place attributions, with Otto von Friesen and Arwid Johannson returning to the western end of the Carpathians; Hermann Schnedier placing the Goths in the Black Sea area (Crimean Goths); and Niels Clausen Lukman reanalyzing the tale, not in the context of Jordanes' history but in that of Ammianus Marcellinus. Lukman shifted the date to 386 CE, when a mass migration of peoples under Odotheus (conflated with Hlothr) was destroyed by the Romans on the Danube; in his reconstruction Heithrekr is the visigothic Athanaric. In an analysis of parts of the tale, identifies the place where Angantyr revenges his father's (Heithrekr) killing by slaves as being at the foot of the Carpathians, using linguistic analysis based on consonant shifts (see Grimm's Law) in the term "Harvath Mountains". The place "Árheimar" in "Danparstathir" mentioned in association is unidentified, though "Danpar-" has been assumed to be some form of the river Dnieper. Similarities with the Battle of Nedao (454 CE) have also been noted.
