As the King Tupac Inca had determined to go to the coast valleys, to bring the inhabitants under his sway, he descended to that of Tumbez, and was respectfully received by the people; to whom he showed much kindness, and put on the dress which they usually wore, to give them more contentment. He commended the principal men for wishing to receive him as their lord without going to war, and promised to look upon them as his own children. They, being well satisfied to hear his good words and to see the way in which he treated them, gave their obedience in good faith, allowing governors to remain with them, and buildings to be erected. But some Indians affirm that Tupac Inca passed on without making any settlement in this district, and that there was none until the reign of Huayna Ccapac. If we attend to everything they say, we shall never come to any conclusion.

Leaving this valley, the Inca visited the others on the sea coast, making a royal road as he travelled, very large and grand, as may be seen from what now remains of it. In most parts he was served, and the people. came to him with presents, but occasionally there was resistance to his advance. However, there was no part where the people did not eventually submit and become his vassals. In these valleys he rested for some days, drinking and enjoying his pleasures, while he rejoiced to look upon the beauty of the country. Great edifices and temples were built by his order.
