Ehhh, I appreciate the depth of the lecture, although I disagree on his positioning of the two armies. he also comes off as a sort of pompous ass, but hey, so do most professors.
The cool thing about this is that these kids paid tens of thousands of dollars to be there and sit there in that room and hear that lecture (of course they get to see the archaeological digs in person, which is a bonus; a friend of mine got to stand IN the dig that revealed the foundations of the Painted Stoa in the Agora!), while we can watch the lecture essentially for free.
enjoy!
