It should not appear to learned persons that, in adopting this course, I deviate from the plan of my work; for my aim is to make the matter more clear and intelligible, as I have declared. I propose to write with brevity, and not to dwell on minute details, and in the same way I shall afterwards proceed to narrate the events of the reigns of the Incas, and their succession, down to the death of Huascar, and the entry of the Spaniards which brought them to an end. I desire that those who may read my work, should understand that among all the Incas, the number of which was eleven, three were most capable of governing their lordships, insomuch that the Orejones who relate their history do not cease to praise them. These were Huayna Capac, Tupac Inca Yupanqui his father, and Inca Yupanqui, father of one and grandfather of the other. It may also be assumed that, as these monarchs flourished in recent times, the kingdom must still be full of people who knew Tupac Inca Yupanqui, and accompanied him in his wars, and that they heard from their fathers what Inca Yupanqui did during his reign; so that it may be said that the events took place almost before their eyes. They, therefore, have more light to throw upon this period, and are well able to relate the events; although much has been forgotten touching the history of the earlier reigns. Yet it is certain that they do not lose the memory of events for many years, although they know not the use of letters, as I have already observed in the first part of this Chronicle.[86] The use of letters has not been found either in any part of this kingdom or throughout the whole of the Indies. With these remarks we will now proceed with the narrative. CHAPTER X. _How the lord, after he had assumed the fringe of sovereignty, was married to his sister the Coya, which is the name of the queen, and how it was permitted that he should have many women, although among them all the Coya alone was the legitimate and principal wife._
