_How Inca Yupanqui set out from Cuzco and marched to the Collao, and of what happened there._
These Indians have no letters, and can only preserve their history by the memory of events handed down from generation to generation, and by their songs and _quipus_. I say this, because their narratives vary in many particulars, some saying one thing, and others giving a different version. Human judgment would not suffice to decide what is truest, without taking, from these various stories, what the people themselves consider to be most accurate, for record. I write this for the benefit of the Spaniards who are in Peru, and who pretend to a knowledge of many native secrets. They are aware that I knew and understood what they think that they know and understand, and a good deal more; and that from all this, I have decided upon writing what they will see, having worked hard at collecting the materials, as they themselves well know.
The Orejones relate that, the affairs of Inca Yupanqui being in this state, he determined to set out from Cuzco with a large force, to march to the region they call Collao. Leaving a governor in the city, he set out and marched until he arrived at the great town of Ayaviri. The people did not wish to come to him in due form. The Inca, therefore, took them by surprise, and killed all the inhabitants, both men and women, doing the same to the people of Copacopa. The destruction of Ayaviri was such, that nearly all perished. There only remained a few who were horrified to see so great a calamity, and wandered, like mad creatures, in the fields, calling on their ancestors with great moanings and words of fear.[211] The Inca hit upon the useful idea of planting a colony in the beautiful meadows and fields of Ayaviri, near which the bright river flows; and he ordered that sufficient _mitimaes_ should come, with their women, to people the district. So it was done, and large buildings with a temple of the Sun were erected for them, with a storehouse and provisions. Thus Ayaviri, peopled by _mitimaes_, continued to be more prosperous than it was before; and the Indians who survived from the wars and the cruelty of the Spaniards, are all descended from _mitimaes_, and not from natives, as has been written.
