It is known that History, as a sum of experiences, has always been a concern of the man, thinker, writer. That is why it is advisable to periodically return to various aspects of our past.  The 18th century chroniclers also had a dramatic outlook on the period they lived in, attempting to convey that to posterity. Images of cohabitation in the same great theater of the world; exercises of knowledge, understanding, acceptance/non-acceptance, those of distinct dimensions at different levels are found in all the chronicles. From this perspective we have to approach their writing: reflections, openness to foreign sources, interest shown to the other, who is of another ethnicity, or confession - all these drawn on their cultural horizon, different from one chronicler to another, from one epoch to another. Built on a culture of difference, that of alterity, from which not only the image of others but also the self-image are revealed. For the experience of knowing each other has as finality an introspective act.
