Gold, a BBC World Service programme about Gold, and man's obsession with it through the ages. It's available via the Documentary podcasts archive, should you choose to subscribe (it's a three-parter, apparently), and seriously, it's well worth a listen, if you've got c20 minutes to spare: from Jo'burg in SA to panning for the stuff in a Scottish burn, and from Alexander the Great to the obsession of contemporary 'collectors'. Interlaced, too, with a reading of Ovid's tale of King Midas.

Documentary blows a little hot and warm (never quite cold), so not every instalment of the podcast might be to your taste, but hey, that's what the 'skip' button's for on the 'pod, right?
