"I firmly believe that thou, O Christian king and lord, hast been very cruel and ungrateful to me and my companions for such good service, and that all those who write to thee from this land deceive thee much, because thou seest things from too far off. I and my companions, no longer able to suffer the cruelties which thy judges and governors exercise in thy name, are resolved to obey thee no longer.... Hear me! O hear me! thou king of Spain. Be not cruel to thy vassals.... Remember, King Philip, that thou hast no right to draw revenues from these provinces, since their conquest has been without danger to thee. I take it for certain that few kings go to hell, only because they are few in number; if they were many, none of them would go to heaven. For I believe that you are all worse than Lucifer, and that you hunger and thirst after human blood; and further, I think little of you and despise you all; nor do I look upon your government as more than an air bubble....
"In the year 1559 the Marquis of Canete entrusted the expedition of the river of Amazons to Pedro de Ursua, a Navarrese, or, rather, a Frenchman, who delayed the building of his vessels till 1560. These vessels were built in the province of the Motilones, which is a wet country, and, as they were built in the rainy season, they came to pieces, and we therefore made canoes and descended the river. We navigated the most powerful river in Peru, and it seemed to us that we were in a sea of fresh water. We descended the river for three hundred leagues. This bad governor was capricious, vain, and inefficient, so that we could not suffer it, and we gave him a quick and certain death. We then raised Don Fernando de Guzman to be our king.... Because I did not consent to their evil deeds they desired to murder me. I therefore killed the new king, the captain of his guard, his lieutenant-general, four captains, his major-domo, his chaplain who said mass, a woman, a knight of the Order of Rhodes, an admiral, two ensigns, and five or six of his servants. I named captains and sergeants, but these men also wanted to kill me, and I hanged them. We continued our course while this evil fortune was befalling us, and it was eleven months and a half before we reached the mouths of the river, having travelled for more than a hundred days over more than fifteen hundred leagues. This river has a course of two thousand leagues of fresh water, the greater part of the shores being uninhabited, and God only knows how we ever escaped out of that fearful lake. I advise thee not to send any Spanish fleet up this ill-omened river, for, on the faith of a Christian, I swear to thee, O king and lord, that if a hundred thousand men should go up, not one would escape....
