About two leagues beyond the fortress of Gruarco is a rather large river called Lunahuana, and the valley which it forms is like all the rest. Six miles further on is the large and beautiful valley of Chincha, so far famed throughout Peru, as well as feared in former days by the other natives. When the Marquis Don Francisco Pizarro, with his thirteen companions, discovered the coast of this kingdom, it was said on all sides that Chincha was the fairest and best part of it. Thus it was that, by reason of the fame borne by the place, and without knowing the secrets of the soil, he sought from his Majesty the government of a territory extending from the river of Santiago or Tempulla to this valley of Chincha.

As to the origin of the Indians of Chincha, they say that, in time past, a quantity of them set out under the banner of a valiant captain of their own tribe and arrived at this valley of Chincha, where they found many inhabitants, but all of such small stature that the tallest was barely two cubits high. The new comers being valiant, and the natives cowardly and timid, the former gained possession. They also affirm that all the natives perished, and that the fathers of the grandfathers of men now alive saw their bones in certain tombs which were as small as has been described.
