Herodotus was a Greek historian who lived in Halicarnassus in the fifth century BC. He has been called “The Father of History”. He writes that a war was brewing between the Medes and the Lydians in what is today Turkey. The story goes that Cyaxares the Great, the King of the Medes had insulted Scythian warriors. The warriors killed one of his sons in revenge, and sold him to the Medes. They then retreated to Sardis, the land of Lydians.
Cyaxares asked for the Scythians to be return the body and Alyattes II, The King of Lydia refused. Cyaxares put a army of Medes together and invaded Lydia. The war went on for 5 years with little progress. It as a large and bloody stalemate. One day, during a battle,there happened was a lunar eclipse, and the omen obsessed religious leaders took it to heart that this was a sign to end the conflict. NASA has since retrocalculated that the eclipse happened on the 3rd of Sept 609 BC or on the 4th of July in 587 BC, when such dusk-time lunar eclipses did occur.
“Afterwards, on the refusal of Alyattes to give up his suppliants when Cyaxares sent to demand them of him, war broke out between the Lydians and the Medes, and continued for five years, with various success. In the course of it the Medes gained many victories over the Lydians, and the Lydians also gained many victories over the Medes. Among their other battles there was one night engagement. As, however, the balance had not inclined in favour of either nation, another combat took place in the sixth year, in the course of which, just as the battle was growing warm, day was on a sudden changed into night. This event had been foretold by Thales, the Milesian, who forewarned the Ionians of it, fixing for it the very year in which it actually took place. The Medes and Lydians, when they observed the change, ceased fighting, and were alike anxious to have terms of peace agreed on.
As part of the terms of the peace agreement, Alyattes’s daughter Aryenis was married to Cyaxares’s son Astyages, and the Halys River (now known as the Kızılırmak River) was declared to be the border of the two warring nations.”
