This account comprehends the Giants, Olmecs, Xicalancas, Toltecs, Chichimecas, Aculhuas, Tepanecas, Otomies, Tenochcas and Tlatelocas. It is a literal translation to modern English of the ancient manuscript ""Obras Historicas"" (ASIN B003ZSURG6), written in the 1600s by Fernando de Alva Ixtlilxochitl (1578 - 1650). Only the first ten chapters are translated because these concern with the origin and subsequent genealogies of these people. The first chapter has a fiction-like quality in that the account origin is the Sky and this beginning dictates the branching of the genealogies of the first kings, princes and princesses in these Mesoamerican regions. The genealogies of the Sky are mingled with the lives of the peoples in these regions. Their history does not have an origin or focus point without the account of their Sky gods.
