S HIS ELDER BROTHER NAMED INCA URCO.

Pachacuti Inca Yupanqui found himself so powerful with the companies he
had got together by liberal presents to all, that he proposed to
subjugate by their means all the territories he could reach. For this he
mustered all the troops that were in Cuzco, and provided them with arms,
and all that was necessary for war. Affairs being in this state
Pachacuti heard that his brother Urco was in a valley called Yucay, four
leagues from Cuzco, and that he had assembled some people. Fearing that
the movement was intended against him the Inca marched there with his
army. His brother Inca Rocca went with him, who had the reputation of
being a great necromancer. Arriving at a place called Paca in the said
valley, the Inca went out against his brother Urco, and there was a
battle between them. Inca Rocca hurled a stone which hit Urco on the
throat. The blow was so great that Urco fell into the river flowing down
the ravine where they were fighting. Urco exerted himself and fled,
swimming down the river, with his axe in his hand. In this way he
reached a rock called Chupellusca, a league below Tampu, where his
brothers overtook him and killed him.

From thence the Inca Pachacuti Yupanqui, with his brother Inca Rocca
marched with their troops to Caquia Xaquixahuana to see his father who
refused ever to speak with or see him, owing to the rage he felt at the
death of Inca Urco. But Inca Rocca went in, where Viracocha was and
said, "Father! it is not reasonable that you should grieve so much at
the death of Urco, for I killed him in self defence, he having come to
kill me. You are not to be so heavy at the death of one, when you have
so many sons. Think no more of it, for my brother Pachacuti Yupanqui is
to be Inca, and I hold that you should favour him and be as a father to
him." Seeing the resolution of his son Inca Rocca, Viracocha did not
dare to reply or to contradict him. He dismissed him by saying that that
was what he wished, and that he would be guided by him in everything.
With this the Inca Yupanqui and his brother Inca Rocca returned to
Cuzco, and entered the city triumphing over the past victories and over
this one.

The triumph was after this manner. The warriors marched in order, in
their companies, dressed in the best manner possible, with songs and
dances, and the captives, their eyes on the ground, dressed in long
robes with many tassels. They entered by the streets of the city
