Erchempert (Latin: Erchempertus; fl. 888–889) was a Benedictine monk of the Abbey of Monte Cassino in Italy in the final quarter of the ninth century. He chronicled a history of the Lombard Principality of Benevento, in the Langobardia Minor, giving an especially vivid account of the violence in southern Langobardia. Beginning with Duke Arechis II (758–787) and the Carolingian conquest of Benevento, his history, titled the Historia Langobardorum Beneventanorum degentium (The History of the Lombards living in Benevento), stops abruptly in the winter of 888–889. Just one medieval manuscript of this text survives, from the early fourteenth century. Source: Wikipedia (en)
