"Xerxes was dissuaded from this decision by sound advice, but was spurred onto it again and again by his dreams"

   An account from Book VII of Herodotus’ Histories, in which Xerxes is persuaded to invade Greece by a visitation in his dreams.  His adviser Artabanus dismisses the vision’s importance, arguing that dreams merely reflect the day’s concerns rather than divine will – he repents after himself receiving a nocturnal visit from the same figure.
