Other immigrations are mentioned by tradition, but no definite account of their origin is given. It seems probable, however, that certain tribes, called Mam[34] or Mem, came from the North and destroyed both Tula and Nachan. Another inroad, led by the four chiefs Balam Agab, Balam Quitze, Mahucutah, and Iq Balam, advanced as far as Mount Hacavitz in Verapaz, north of Rabinal; and here these chiefs remained as freebooters and founded that tribe known as the Quichés. They constantly attacked their neighbors, and offered the captives taken in these encounters to their god Tohil, who, with Avilitz and Hacavitz, formed the trinity in the Quiché cult. Force and stratagem proving of no avail against them, the surrounding tribes gradually submitted; and when peace was established, the four captains conveniently disappeared, leaving the government in the hands of three sons, Iq Balam having no offspring. And now we have the curious account given by the unknown author of the “Popul Vuh,” or sacred book of the Quichés, of which two translations exist, one in Spanish by Ximenes, the other in French by the Abbé Brasseur de Bourbourg. The annalist tells us that before the departure of the four chiefs they charged their sons to undertake a journey to the East; and the new rulers, in obedience to this command, passed the sea easily (Lago de Izabal?) and came to the city of a great lord called Nacxit,[35] who instructed them in the art of government and invested them with the feather umbrellas,[36] throne, and other symbols whose Indian names both translators fail to interpret. On their return all their subjects received them with joy; but so numerous had the people become that Mount Hacavitz could no longer contain them, and now began the dispersion of the tribes. One branch went westward and founded Izmachi, a city some distance westward of Santa Cruz del Quiché. No rude Indios these who built Izmachi of stone and mortar.
