“Good. Then we'll have our battle in the shade.”
It is said that on the eve of battle, he was told by a native of Trachis that the Persian archers were so numerous that, when they fired their volleys the mass of arrows blocked out the sun. Dienekes, however, quite undaunted by this prospect, remarked with a laugh, "Good. Then we'll have our battle in the shade."
Herodotus, in Histories; the remarks of Dienekes have sometimes become attributed to Leonidas.
