Once upon a time, back in about the 5th Century, there were fierce tribes of Mongol horsemen who rode across what is now Europe, raping and sacking and pillaging and generally having a very good time at the expense of the local residents. Several of their leaders became famous in the sense that they were feared by Western Europeans who did not wish to be raped, sacked and pillaged. One of these was Atelo, a descendant of Atilla, and the fear of him was so widespread and intense that 5th Century psychiatrists defined it in their diagnostic manual as atelophobia.
