classes are essentially different species. A second interpretation, however, is that ″the names of the three couples - great-grandfather and great-grandmother, grandfather and grandmother, and finally father and mother - might seem to imply that the various classes of mankind share a common heritage.″ The poem has been viewed as suggestive of social progress over time, so that one class may aspire to move up. According to Hill, however, most agree that this second view is too benevolent and that in fact the poem reveals that for the Vikings: The different orders of mankind are indeed fixed and unchangeable, but in the very beginning there was a certain kinship between the different orders of mankind, a kinship suggested by the fixed and yet linked sequence of the genealogical chain. Theories A marriage by Konr the young into the family of Dan and Danþír seems to be where the tale was headed, as seen in the two other sources that mention this Rígr. According to Arngrímur Jónsson's Latin epitome of the lost Skjöldungasaga: Ríg (Rigus) was a man not the least among the great ones of his time. He married the daughter of a certain Danþír, lord of Danpsted, whose name was Dana; and later, having won the royal title for his province, left as his heir his son by Dana, called Dan or Danum, all of whose subjects were called Danes. The other tradition appears in chapter 20 of the Ynglinga Saga section of Snorri Sturluson's Heimskringla. The story speaks of King Dygvi of Sweden: Dygvi's mother was Drótt, a daughter of King Danþír, the son of Ríg, who was first called konungr in the Danish tongue. His descendants always afterwards considered the title of konungr the title of highest dignity. Dygvi was the first of his family to be called konungr, for his predecessors had been called dróttinn [chieftain], and their wives dróttning, and their court drótt (war band). Each of their race was called Yngvi, or Ynguni, and the whole race together Ynglingar. Queen Drótt was a sister of King Dan Mikillati, from whom Denmark took its name. Despite genealogical discrepancies (to be evaded only by imagining more than one Danþír and more than one Dan) the accounts relate a common tradition about the origin of the title konungr (king). Konr the young, whose magical abilities are so emphasized, is as much a magician as a warrior: a
