Explanation:
Chronology is one of the auxiliary sciences of history. Its purpose is to determine the temporal order of historical events. Events happen in a place and at a specific time. Space and time are two coordinates that allow us to understand reality. A chronological order is an order established based on a temporal sequence. The expression is often used to account for real historical events or fictional narratives where events are presented in a virtual temporal order.
It is important to distinguish the <em>chronological order</em> from a <em>temporal succession</em>. Both are closely linked but differ in fundamental circumstances. Indeed, temporal succession is the order that events have over time. In a different way, the chronological order usually refers to the way in which real events are enunciated. Indeed, the chronological order is a type of circumstance related to discourse, and therefore, to communication.
