Back in 2002, we marked the millennium of the massacre with a small conference here at Nottingham. Although the papers were not published then, three of them were given again, in revised form, at a conference in Copenhagen, and then published in the proceedings of the Seksogtyvende tværfaglige vikingesymposium (2007). For those who are interested, I'd particularly recommend Julia Barrow's paper on 'Bishop Brictius - Saint Brice', which links the massacre to the autumn slaughter of livestock, and concludes:
Therefore, if we picture ourselves in Oxford in November 1002 we can imagine the Cornmarket and the High full of animals brought in from the surrounding countryside waiting to be sold to butchers and killed. ... The animal slaughter would probably still have been continuing two days later on St Brice's day, and Æthelred would probably have viewed this day as more appropriate for a massacre of Danes than St Martin's day, Brice being a much less popular, and much less significant, saint than St Martin.
