To Manco Ccapac succeeded his son, Sinchi Roca. His proper name was Roca (with the pronunciation of the R soft). This word has no meaning in the general language of Peru, but it may have some signification in the special idiom of the Yncas, although I am not aware of it. Father Bias Valera says that roca means a prudent and wise prince, but he does not tell us in what language. He notices the pronunciation of the R soft, as we have done. He recounts the excellence of the Ynca Roca, as we shall see presently. Sinchi is an adjective signifying “valiant,” because they say that he was of a brave disposition, and very strong, although he did not display these qualities in battle, as he did not wage war upon anyone. He had the advantage of all persons of his time in wrestling, running, leaping, throwing a stone or lance, and in every other feat of strength.

This prince, having completed the solemn obsequies of his father, and taken the crown, which was a red fringe, proposed to extend his territory. For this purpose he summoned the principal curacas of his father's court, and addressed them in a long and solemn discourse. Among other things, he said that, in compliance with his father's policy when he returned to heaven, he desired the conversion of the Indians to a knowledge of the worship of the Sun.
