The chronicle of John of Worcester is one of the most important sources of early English history. A complete edition and translation is being published for the first time. Volume II covered the annals from 450 to 1066: Volume III takes the story from 1067 to 1140. Patrick McGurk has used all available manuscript evidence, and also publishes the Gloucester interpolations made to one of the manuscripts. The latter are of the greatest interest for the first five years of King Stephen's reign.
