I just finished listening to the last podcast in Dan Carlin's series titled the Death Throes of the Republic on his Hardcore History show. Really well executed and fascinating to listen to. Dan's got a way of making over 12 hours of ancient Rome history fly by. I even managed to consume the last podcast (nearly 5:30 long) in a two to three day period. I highly recommend the series to anyone who is even remotely curious about ancient Roman history.
