Histories

Xerxes was now intent on the expedition and then saw a third vision in his sleep, which the Magi interpreted to refer to the whole earth and to signify that all men should be his slaves. This was the vision: Xerxes thought that he was crowned with an olive bough, of which the shoots spread over the whole earth, and then the crown vanished from off his head where it was set.

The Magi interpreted it in this way, and immediately every single man of the Persians who had been assembled rode away to his own province and there used all zeal to fulfill the kings command, each desiring to receive the promised gifts. Thus it was that Xerxes mustered his army, searching out every part of the continent.
