and as they still carried on the war with equally balanced fortune, in the sixth year a battle took place in which it happened, when the fight had begun, that suddenly the day became night. And this change of the day Thales the Milesian had foretold to the Ionians laying down as a limit this very year in which the change took place. The Lydians however and the Medes, when they saw that it had become night instead of day, ceased from their fighting and were much more eager both of them that peace should be made between them. And they who brought about the peace between them were Syennesis the Kilikian and Labynetos the Babylonian: 95 these were they who urged also the taking of the oath by them, and they brought about an interchange of marriages; for they decided that Alyattes should give his daughter Aryenis to Astyages the son of Cyaxares, seeing that without the compulsion of a strong tie agreements are apt not to hold strongly together. Now these nations observe the same ceremonies in taking oaths as the Hellenes, and in addition to them they make incision into the skin of their arms, and then lick up the blood each of the other.
