Plural of chronology; systems or arrangements of events in the order they occurred, or the branch of study dealing with arranging events in time sequence.
From chronology (Greek chronos + -logia, 'study of') plus English plural -es. The word emerged from medieval scholarship's need to establish precise timelines of historical events.
Different chronologies of ancient events frequently conflict—scholars arguing about whether the Egyptian pyramids or Stonehenge came first is literally scientists competing to create the correct chronology of human civilization.
