Alexander the great

For the past couple weeks in school, I have been watching a historical documentary. In it, the narrator traces the footsteps of the great Greek general, Alexander the great. It is cool because the film crew ad Michel Wood, the narrator, have to hitch hike, walk on small mountain passes, and get rides with trading caravans on camels. That seems like a fun occupation to me. Also, you get to learn a lot about Alexanders tactics, such as his method of invading Tyre, a small island city. To cross the half mile gap between the two landmasses,  Alexander built a massive dirt walkway 200 miles wide for his army to cross.
Also The documentary helps you realize how big people thought the world was back then. The Greeks thought that you could sail straight from the Black Sea to Britain or India, though today we know it is a land locked sea, and is far from any routes close to northern Europe or India. When Alexander found out that the Black Sea was not the edge of the world that changed his tactics.
