What Made Alexander So Great?

Bust of Alexander the Great, British Museum Marco Prins

... Aside from the fact that, if the dude depicted in the portraits is he, he's about as hot as they get! A mini history lesson (because, you know, all those people back then were pretty much us sans Internet and The Colbert Report, more's the pity). Did you know, for example, that Alexander was a great partier? Or that when he defeated Persia (47,000 to 200,000, btw), he married a Persian dancer named Roxanne? Or that he untied the original Gordian Knot (well, actually, he cut it in half with his sword)? Or that, when Thebes revolted, he had all its 30,000 inhabitants killed or sold into slavery and then razed the city (after which there were no more revolts in Greece)?: http://www.livescience.com/11315-top-10-reasons-alexander-great-great.html
