Thanks to rogueclassicism for the following links, both of which cover some of the history of Carthage and one to Richard Miles’ Carthage Must be Destroyed.
Richard Miles’ was on ABC Radio National’s program By Design discussing Carthage - and where is it now? (approximately 12 minutes). A wide ranging discussion, including how the myth started that Rome sowed the ground of Carthage with salt after the Third Punic War.
From Stuff Your Missed in History Class, there is a podcast for the Rise and Fall of Carthage (link goes to rogueclassicism). A conversational introduction covering some key points in Carthage’s history (approximately 24 minutes).
