Battle of Plataea
The motto is "As long as (the sun) follows his course" (, "est' an (o ilios) tin aftin odon ii"). Before the Battle of Plataea, Mardonius offered the Athenians peace terms, with the hope of dividing the Greek forces. The Athenians responded with "As long as the sun follows his course, as he does now, we shall not come to a compromise with Xerxes".
