the domestic service of the royal palace, being employed to bring fruits, game, and (we are seriously informed by the historian) even fish, from the tropical coast region, for the imperial table. [Illustration: SHOWING THE TWELVE-ANGLE STONE, RUINS AT CUZCO.] Tupac-Yupanqui is named by some authorities as the successor of Inca Yupanqui, to whom they give all the glory of the long and brilliant reign which others credit to Tupac-Yupanqui. On the other hand, many historians say that Inca Yupanqui’s reign was brief and uneventful, except for his campaigns, undertaken to subdue the Mojos of the region of the Beni and the Chiriguanas of the Bolivian Chaco. He failed in both enterprises and then turned his armies toward Quito, though with little better success. Tupac-Yupanqui had a young son, however, who was destined to bring the power and prestige of the Children of the Sun to the very zenith of glory. This prince, whose name was Huayna-Ccapac, took command of the imperial forces in the later years of his father’s life and marched against the king of Quito, whom he defeated, gaining possession of his kingdom. Alas, the conquest of Quito, the most brilliant victory yet won by the Children of the Sun, proved to be “the beginning of the end,” the source of the disunion of the great Inca empire, a calamity which contributed in an important degree to make it possible for a small group of invaders to accomplish the downfall of one of the most powerful monarchies that ever developed among a primitive people!
