Curiously, Croats are seemingly the only Slavic people who had a saga about the period of their migration, and the names are the earliest example of pan-Slavic totemic heroes. Also, compared to other early medieval stories none of them mentions female personalities, but do late medieval Kievan, Polish and Czech chronicles, which could indicate a specific tribal and social organization among the Croats. For example, Łowmiański considered the Mazovians, Dulebes, Croats and Veleti among the oldest Slavic tribes because Mazovians ethnonym was often related to Amazons ("-maz-") while the land of women in North Europe was mentioned by Paul the Deacon, Alfred the Great, as well women's city West of Russian lands by Abraham ben Jacob. Another vagueness is a reason and meaning that one of the brothers had a Croatian ethnonym as a name, perhaps indicating he was more important than the other brothers, it was the most prominent clan or tribe around which other gathered, or that the Croats were only one identity among others with which the Adriatic Croats tried to bring legitimacy to the Croatian Kingdom.
