After Huayna Ccapac had given orders respecting the things mentioned in the last chapter, it was reported to him that there were certain tribes near the territory of the Chachapoyas which might be conquered, and that on the way he might subdue the Chachapoyas who had rebelled. He gave orders to his orejones and assembled a large army. He set out from Cuzco, having first offered sacrifices and observed the calpa[116]. On the route he took, he reformed many things. Arriving at the land of the Chachapoyas, they, with other neighbouring tribes, put themselves in a posture of defence. They were eventually vanquished and treated with great severity. The Inca then returned to Cuzco and triumphed at the victory gained over the Chachapoyas and other nations.

[Note 116: Calpa means force, power. Calpay work. Calparicu "one who gives strength," used for a wizard. The Calpa was a ceremony connected with divination.]

While he was absent on this campaign, he left as Governor of Cuzco one of his illegitimate brothers named Sinchi Rocca, an eminent architect. He built all the edifices at Yucay, and the houses of the Inca at Casana in the city of Cuzco. He afterwards built other edifices round Cuzco for Huayna Ccapac, on sites which appeared most convenient.
