This is a translation of the eleventh-century Latin Annals of Lampert, monk of Hersfeld, with detailed commentary and introduction. No translation has hitherto been published in English, despite the fact that it is one of the best known of all the narrative sources of the Middle Ages, constantly mentioned in the English secondary literature. Lampert produced the most detailed account of the events of 1056–77 (the minority of Henry IV of Germany and the first decade of his personal rule), a period of crisis and rebellion culminating in the conflict between the king and Pope Gregory VII. He is widely regarded as 'the unrivalled master among medieval historians' and 'a superb story-teller', noted for his vivid characterisation and narrative. An English translation of this work is of the greatest value to teachers and students of medieval history and also of interest to the general reader of European literature.
