Professor Ed Watts is a reliably brilliant guest on the show. In this episode he looks at Sulla's career and the blight the cast on the Roman Republic. Ed argues that it is impossible to understand any the great characters - Caesar, Cicero, Cato, Pompey and so on - without understanding the scarring effect of Sulla's rule. In Ed's view Caesar emerges from all this as a man with terrible ambition and many faults but ultimately redeemed by his refusal to follow Sulla's example. Refreshingly revisionist stuff.
You can read more about the issues we talk about in Ed's book Mortal Republic. It is extremely entertaining and fast paced without sacrificing scholarship. Highly recommended.
