Before battle was joined they say that someone from Trachis warned him how many Persians there were by saying that when they fired their bows, they hid the sun with the mass of arrows. Dianeces, so the story goes, was so dismissive of the Persian numbers that he calmly replied, "All to the good, my friend from Trachis. If the Persians hide the sun, the battle will be in shade rather than sunlight."
