When Lindisfarne monastery was attacked in 793AD the monk Alcuin described the church of St Cuthbert, "splattered with the blood of the priests." New Generation Thinker Eleanor Rosamund Barraclough, from Durham University, takes this moment as the starting point for an exploration of the power battles between Vikings and Anglo Saxons which led to the symbolic battles of 1066. Recorded on Saturday 26th October 2013 in front of a live audience at Sage Gateshead as part of Radio 3's Free Thinking festival.
