The Marathon 2500 project celebrates the 2500 year anniversary of the Battle of Marathon. I found this though AWOL this morning. The Project is providing a series of live online lectures (i.e. webinars), for which one can register for free, and ask questions via email.
Paul Cartledge, a wonderful Greek History scholar who specializes in the Spartan history among other things, gives the first lecture. You can download the first lecture here, and supposedly you can download the podcast, although I cannot figure out how (if someone figures it out, please comment and let me know). The only problem with the lecture is that the sound quality is very poor. However, the successive lectures have a significantly better sound quality. The slideshow that accompanied Cartledge's lecture can be found here.
The second lecture is by Peter Krentz and can be found here. I was only able to download it via the RealPlayer extension for Firefox, but there are probably other ways to do this. The website claims that you can download it directly off the site. I know he had a slideshow, but I am not sure how to access it. If anyone figures it out, please comment.
The third lecture will take place on November 10th. It will be given by Victor Hanson and it is entitled "A Soldier's Life." Registration is free and you can listen to the event live and send in questions.
The group has also put together a Herodotus reading group (in English) using the Landmark Herodotus. Robert Strassler, the editor and compiler of the Landmark Series, will also lecture on May 10, 2011.
