585 BCE
Battle Of Halys Eclipse Truce
About this moment
The eclipse of Thales was a solar eclipse, which was, according to the ancient Greek historian Herodotus (writing about 150 years later), accurately predicted by the Greek philosopher Thales of Miletus. If Herodotus' account is accurate, this eclipse is the earliest recorded as being known in advance of its occurrence. According to Herodotus, the change of day into night was interpreted as an omen, and interrupted a battle in a long-standing war between the Medes and the Lydians in Anatolia (present-day Turkey).
