Some of you may remember a couple of passing references to the excellent "The History Of Rome" podcast (iTunes link) in this blog: if not, and you have any interest at all in the history of Rome (duh!), I can't recommend this strongly enough.
Mike Duncan (the author of the above) wrapped it up about a year ago so he could cope with the arrival of his new son, but he's BACK, with "Revolutions" (iTunes link), a weekly podcast series examining great political revolutions. Currently he's on the English Civil War.
Haven't had chance to listen yet, but if the previous podcast is anything to go by, it promises to be awesome. Go check it out.
