This then is how the Lacedaemonians and Thespians conducted themselves, but the Spartan Dieneces is said to have exhibited the greatest courage of all. They say that he made the following speech before they joined battle with the Medes: he had learned from a Trachinian that there were so many of the barbarians that when they shot their missiles, the sun was hidden by the multitude of their arrows.
He was not at all disturbed by this and made light of the multitude of the Medes, saying that their Trachinian foreigner brought them good news. If the Medes hid the sun, they could fight them in the shade instead of in the sun. This saying and others like it, they claim, Dieneces the Lacedaemonian left behind as a memorial.
