For anyone interested in life in pre-Roman Britain there is an excellent podcast on the Druids – in iTunes, go to BBC and search for In Our Time – edition dated 20 Sept 2012. There was also an edition about Hadrian's Wall on 12 July and the most recent edition (4 Oct) is about Gerald of Wales, but I haven't listened to that one yet.
The Gerald of Wales podcast is very interesting and easy to listen to. Sounds like he was quite a guy – the kind that you would go down the pub for the evening and enjoy a good conversation (even though he was a priest). Although Jamie hasn't said much yet about the Norman occupation, this will be helpful background on one of the main sources for the Norman period.
