During this period, Greek culture and spread throughout the Mediterranean and Near Eastern world.The term Hellenistic literally means "Greek-like." So, during this period Greek art, philosophy, mathematics, and many other aspects of Greek culture spread through the areas Alexander had conquered. Alexander, even in death, was responsible for disseminating the culture of the Greeks into many other culture, letting it take root and influence other cultures for millennia.
