The King Ynca Rocca, whose name, as has already been quoted from the missionary Bias Valera, means a prudent prince of mature judgment, took the red fringe on the death of his father; and, having celebrated the funeral ceremonies, passed three years in visiting all parts of his dominions. Soon afterwards he ordered his warriors to be assembled, to continue the conquests in the direction of Chincha-suyu, which is to the northward of Cuzco. He caused a bridge to be made across the river Apurimac, which is on the high road from Cuzco to the City of the Kings; for it appeared to him to be beneath his dignity that, being now king, he should cross that river with his army in balsas, as he had done when he was only prince. At that time the late Ynca had not ordered a bridge to be made, because the provinces in that direction were not then subjugated.

As soon as the bridge was made, the Ynca started from Cuzco with 20,000 men, and four masters of the camp. He ordered that the army should cross the bridge in squadrons three abreast, to commemorate its opening. He arrived at the valley of Amancay, which word signifies a lily, and the name was given because of the great number of those flowers that grow there. This flower is different from the lily of Spain both in form and smell, for the Amancay lily is in the shape of a bell, with a green bud, without any smell; and the Spaniards only called it a lily because it resembles one in its green and white colour.
