"After having treated their prisoners well for a long time, giving them all the provisions that they could one, he who is the chief calls a great assembly of his acquaintances. He ties a rope to one of the arms of the prisoner and on the other end, several feet away, out of harm's way, and gives to his best friend the arm to hold; and the two of them, in the presence of the assembled group, slash him to death with their swords. That done, they roast him and eat him together, sending portions to their absent friends. They do this, not as is supposed, for nourishment as did the ancient Scythians; it represents instead an extreme form of vengeance. The proof of this is that when they saw that the Portuguese, who had allied themselves with their adversaries, executed their captives differently, burying them up to the waist and firing numerous arrows into the remainder of the body, hanging them afterward, [the Tupi] viewed these people from another world, who had spread the knowledge of many vices among their neighbors, and who were much more masterly than they in every sort of evil, must have chosen this sort of revenge for a reason. Thinking that it must be more bitter than their own, they abandoned their ancient way to imitate this one.
I am not so concerned that we should remark on the barbaric horror of such a deed, but that, while we quite rightly judge their faults, we are blind to our own."
