Astronomical chronology
Astronomical chronology, or astronomical dating, is a technical method of dating events or artifacts that are associated with astronomical phenomena. Written records of historical events that include descriptions of astronomical phenomena have done much to clarify the chronology of the Ancient Near East; works of art which depict the configuration of the stars and planets and buildings which are oriented to the rising and setting of celestial bodies at a particular time have all been dated through astronomical calculations.
Astronomical dating can be a powerful tool for establishing absolute chronologies, but...
it can easily produce precise and impressive looking results based on invalid assumptions –
results so precise and impressive they may not be questioned by scholars in other fields.
