Your ancestors came to Macedonia and the rest of Hellas [Greece] and did us great harm, though we had done them no prior injury. I have been appointed leader of the Greeks, and wanting to punish the Persians I have come to Asia, which I took from you.
Alexander the GreatI send you a kaffis of mustard seed, that you may taste and acknowledge the bitterness of my victory.

Alexander the Great
