Manco-Capac, here set down as the first Inca, with a marvelous story of his mysterious origin and his miraculous powers as a civilizer, was undoubtedly borrowed from traditions of the origin of civilization in the more ancient times, which had been used by the Incas in support of their claim to direct descent from the sun. In reality, the first Inca was Rocca, or Sinchi-Rocca, and several of the early Spanish writers were sufficiently well informed to see this. The period of the Incas must have been less than five hundred years if their dynasty consisted of no more than twelve or thirteen sovereigns. In other respects, this table of the sovereigns may be substantially correct, for there is a general agreement in regard to the names and the order of succession, although Montesinos maintains that the fifth Inca on the list was borrowed by Garcilasso from traditions of a much more ancient sovereign who was greatly celebrated in the historical poems, or confounded with him. The period of the Incas was very distinct in Peruvian history, but it is now understood that they represent only the last period in the history of a civilization which began much farther back in the past. FERNANDO MONTESINOS. The only Spanish writer who really studied the ancient history of Peru in the traditional and other records of the country was Fernando Montesinos, who went there about a century after the Conquest. He was sent from Spain on service which took him to every part of Peru, and gave him the best possible opportunities for investigation. He was a scholar and a worker, with a strong inclination to such studies, and, during two periods of residence in the country, he devoted fifteen years to these inquiries with unremitting industry and great success. He soon learned to communicate freely with the Peruvians in their own language; then he applied himself to collect the historical poems, narratives, and traditions. He succeeded in getting assistance from many of the older men who had learned of the _amautas_, and especially of those who were trained to read the _quippus_. Nothing was omitted which could aid his purpose. In this way Montesinos made a great collection of what may be called the _old Peruvian documents_, and gained a vast amount of information which no other writer had used or even sought to acquire.
