One of the main established policies by the Jesuit Order to the provincials was to write annually the chronicles of the events of their respective jurisdictions. The reports are known as Annuas Letters and were directed to the Jesuit General in Rome. The 17th Century letters from the New Reign and Quito, specifically those related to the Cartagena School tell facts about the Africans brought to the New World as slaves. Therefore, the letters elaborated representations about the Ethiopians, especially in relationship with their religiosity. They evidenced an imaginary from which the Jesuits created their own method of catechizing. Besides, they developed a vision about Cartagena city and port from the geographical and anthropological perspective.
