In former chapters I have briefly explained how those who were to become nobles were armed as knights, as well as the nature of the ceremonies that took place when the Incas were crowned as kings, by taking the crown, which is the fringe falling as far down as their eyes. And it was ordained by them that he who became king should take his sister, being the legitimate daughter of his father and mother, as his wife; in order that the succession of the kingdom might by that means be confirmed in the royal house. It appeared to them that by this means, even if such a woman, being sister of the king, should not be chaste, and should have intercourse with another man, the son thus born would still be hers, and not the son of a strange woman. They also considered that if the Inca married a strange woman, she might do the same and conceive in adultery, in such a way that, it not being known, the child would be received as a natural born son of the lord. For these reasons, and because it seemed desirable to those who ordained the laws, it was a rule among the Incas that he amongst them all who became emperor should take his sister to wife. She had the name of Coya, which means the Queen, as when the King of Spain marries any princess, who before had her own name, she is called Queen so soon as she enters the kingdom, so they called those of Cuzco Coya.
