This general history of which I took charge by order of Don Francisco de Toledo, Viceroy of these kingdoms of Peru, will be divided into three Parts. The First will be the natural history of these lands, being a particular description of them. It will contain accounts of the marvellous works of nature, and other things of great profit and interest. I am now finishing it, that it may be sent to your Majesty after this, though it ought to have come before it. The Second and Third Parts treat of the people of these kingdoms and of their deeds in the following order. In the Second Part, which is the present one, the most ancient and first peoplers of this land will be discussed in general, and then, descending to particulars, I shall describe [the terrible and inveterate tyranny of] the Ccapac Incas of these kingdoms, down to the end and death of Huascar, the last of the Incas. The Third and Last Part will treat of the times of the Spaniards, and of their notable deeds in the discovery and settlement of this kingdom and others adjoining it, with the captains, governors, and viceroys who have ruled here, down to the present year 1572.
