Greek culture would not have been spread from one end of the world to the other. For instance when his generals set up Hellenistic kingdoms all over the Eastern frontier after his death, they basically set the course of Greek being the dominated culture of its time, i.e. the Toran was first translated into Greek not Latin.
Thanks for the post. That reminds me of the, Roman Baths, in England. Guess they wouldn't be there if Alexander hadn't conquered the known world...
