Today I learned that the Assyrian Emperor-at-the-time (the time being the 14th century B.C.), Ashuruballit, sent a fairly sarcastic message to Pharaoh Akhenaten when he learned that his envoys had been kept standing out in the sun for long enough that they feared for their lives (and came running to him to complain). As quoted in Barry Kemp's Ancient Egypt: Anatomy of a Civilization (page 287):

"Why are my envoys kept standing out in the open sun? They will die out in the open sun. If it does the king good to stand in the open sun, then let him stand out in the open sun himself, and let him die himself. Then there will be profit for the king!"

Hilarious, no? I have basically zero context for the letter, not specializing in the Amarna period, but I can just picture the Assyrian king--I mean, imagine having to deal with Akhenaten in international politics. This guy takes fifteen hundred plus years of religion and social order and tosses it out the window, makes a whole bunch of people in Egypt seriously upset, is probably some kind of crazy fanatic to boot, and now he's kept your envoys standing out in the sun until they're ready to pass out from heat stroke? I'd be pissed, too. And I guess if you're the Assyrian king, you can tell Pharaoh you're going to choke a bitch if he doesn't get your envoys inside, huh.
