Chronology (from Latin chronologia, from Ancient Greek χρόνος, chrónos, 'time'; and -λογία, -logia) is the science of arranging events in their order of occurrence in time, such as in a timeline or other sequence of events. It is also "the determination of the actual temporal sequence of past events".
Chronology is a part of periodization. It is also a part of the discipline of history including earth history, the earth sciences, and study of the geologic time scale.
In a literary work, film, or other narrative, the plot is the mapping of events in which each one (except the final) affects at least one other. Plot is similar in meaning to the term storyline. Simple plots, such as in a traditional ballad, can be linearly sequenced, but plots can form complex interwoven structures, with each part sometimes referred to as a subplot.
E. M. Forster described plot events as relating through the principle of cause-and-effect; the causal events of a plot can be thought of as a selective collection of events from a narrative, all linked by the connector "and so". According to American science fiction writer Ansen Dibell, the term plot highlights important points which have consequences within the story, in the narrative sense. The premise sets up the plot, the characters take part in events, while the setting is not only part of, but also influences, the final story.
