Through a rigorous analysis of Western thought from the 15th to the 16th centuries, this book succeeds in rethinking, from a 21st-century perspective, the nature of the testimonies left to us by the supposed witnesses of the conquest. As a result, the omnipresence of omens and prophecies becomes problematic, especially when one considers that such narratives are nothing more than necessary components of a Western rhetoric that retrospectively justifies the seizure of power in these regions.
