Reports of lunar and solar eclipses are of interest to students of both history and the history of science. Used with care, they can anchor significant historical events in time. Greek literature, like that of other civilizations, has its fair share of such reports. Often they motivate the actions of characters or expose aspects of belief. Sometimes they shed light on the assumptions of the writer. There are three places in the Histories of Herodotus where the author mentions darkenings of the sky (generally taken to be solar eclipses), which have narrative significance and which assist in dating the wars between the Lydians and the Medes (1.74) and between the Greeks and the Persians (7.37 and 9.10).
