One day a messenger brought a tablet sent by a friend who was a prisoner in Persia.

But the closest scrutiny failed to reveal a single word or line on the white waxen surface, and the king and all his noblemen concluded that it was sent as a jest.

Acting on this warning, Leonidas and the other kings assembled their armies and checked the mighty host of Xerxes, which is said to have shaken the earth as it marched.
