Yes. It's quite an old one, and along with Dan Carlin, Mike Duncan is one of the two building blocks of the history podcast world, such as it is. History of Rome was a little rough early on (not that I thought so when first listening to it, but going back it is very noticeable how much it improved over time), but Revolutions is great from start to finish. HoR is absolutely worth listening to, let's be clear, but I think Revolutions is where he hit his stride as a podcaster.
