Yesterday I finished my first series of lectures obtained through iTunesU. I listened to 24 fascinating lectures from Dr Donal Kagan. The lectures began with a normal introduction “Why Ancient Greece matters today.” Then he lectured from quickly from the Homeric period and before up until the death of King Philip of Macedonia (Alexander the Great’s father). The focus of the course dealt with the classical period of 800-300 B.C. I’m now much more informed on Greek history than I was prior! I only wish that he had covered Alexander the Great too. After all, he was named after me ;-).
To those who haven’t checked out iTunesU yet, there is a wealth of good stuff there.

The Hellenistic period is quite interesting, although you will find a lot of the arts in the time have idealised the Classical period. Personally, I believe that NT scholars on the historical Jesus should study Alexander the Great as an ancient historian, then they’ll be a bit less wacky.
Kagan actually brought up skepticism in humorous ways. He called his position the “higher naivete,” which basically meant that he would believe anything an ancient source said unless there was a good reason not too. I like his position ;-).
