In many of the stories of mysioners, travellers and explorers, the Amazon indigenous societies are described as if they had become isolated since the introduction of European colonisation, away from the events and processes that shaped the national societies of the countries in which they now live. Such stories are full of phrases such as "uncontacted tributes; the first white man they have ever seen; where no white man had previously flagged ", etc. and they reveal much more about their authors’ roman’s provisions than about the true state of the indigenous people they are trying to describe. Although less exaggerated, much of the modern ETNOGRAFICA literature in this area shows a similar lack of awareness of the historical background and current situation of the societies described; after advocating teeth to avoid this problem in a short introductory chapter, society is then treated in isolation as not affected by the presence of the missionaries, traders and government officials who threaten to extinguish it.
