Mike Duncan is one of the pioneers of historical podcasting. His “History of Rome” is iconic. And his current “Revolutions” is equally compelling. In this episode, we sit down to chat about Roman history, Rome in cinema, the inevitable comparisons between Ancient Rome and the United States, the factionalism and corruption that brought down the Republic, the connection between ‘The Walking Dead’ + ‘Game of Thrones’ and Roman history, his upcoming book “The Storm Before the Storm,” and the future of his “Revolutions” podcast.
