The chronicle of John of Worcester is one of the most important sources for earlier English history. Completed at Worcester by 1140, it is of considerable interest to historians of both the Anglo-Saxon period and the late eleventh and twelfth centuries. Its annals complement and add significantly to those in the surviving versions of the Anglo-Saxon Chronicle. It has never been adequately translated and a modern edition has long been needed. In this volume, Dr McGurk uses all the available manuscript evidence, as well as the additions for 1122-41 made in a Gloucester continuation of a manuscript started in Johns own handwriting. Taken with these interpolations, the chronicle offers crucial evidence for the first five years of King Stephens reign. The Chronicle will be published in three volumes. Volume II covers the annals from 450 to 1066, and Volume III from 1067 to 1140. Volume I will be published last, and will contain a general introduction and supplementary material.
