BBC Persia recently interviewed David Walsh at the Bloomberg  Space to discuss the differences between the Roman Cult and the worship of the Persian Mithra, who looks very similar (and has a similar name), but is also very distinct from Mithras in how he his worshipped.

A recording of the interview (David features at 11:30 approx) is available online.

David also recently appeared at the Mithraeum for the Emerge Festival (pictured below – image by Caroline Lawrence) giving talks on the cult.
