the accounts in the Gesta Danorum and the accounts in the Ynglinga saga''' tales of a Danish king named Halfdan who became king of Sweden are at all related. Traditions of twin brothers connected with horses appear are a commonplace in Indo-European cultures as are foundation legends about two twin brothers, one of whom kills the other. It is possible that Alrek and Eirik are reflexes of such traditions. Saxo's identification of the legendary Eirík the Eloquent with the legendary Swedish king Eirík probably originated as a flourish by a pro-Danish or pro-Norwegian story teller.
