Oh yes, so I’ve heard — and it makes complete sense, given that he and his armies decimated Classical Persian culture, and essentially brought 4,000 years of Mesopotamian cultural legacy to a crashing halt.
Legacies of conquerors are strange that way. Mention Genghiz Khan’s name in eastern Europe, for example, and you’ll get looks of horror, if not worse — but there’s an airport named after him in Ulaanbaatar, where he’s regarded as a national hero. Same for Timur in Samarkand, Lenin in Moscow, Fatih Sultan Mehmet in Istanbul… all of them killers (or killers-by-proxy) of millions of people.
Maybe we are still waiting for the greatest — but based on the track record of the previous Greats, I’m not sure I’ll want to be around when he arrives on the scene. Still, like you say, whoever he is, he’s likely to be fascinating for future historians.
