He was born on 1025 and died on 1088. Chronicler whose Annales serve as a highly valuable source for the history of 11th-century Germany.
Educated in Bamber, he joined the Beneditine convent of Hersfeld in March 1058 and was ordained the following fall, travelling to the Holy Land the same year. He moved to the Abbey of Hasungen in 1077, helping to initiate its acceptance of the reforms of the Benedictines’ Cluniac order in 1081.
His Annales Hersveldenses was written around 1077-79, covering the period from creation to 1077. An erudite scholar, he was familiar with and used as historical and rhetorical models the works of the Roman historians Livy, Sallust, and Suetonius. His coverage of the period from Genesis to 1040 is brief, primarily a compilation of other sources; but the events from 1040 to 1077 are highly detailed and based on the annals of the Hersfeld Abbey as well as information from other sources and personal experience. Thus the Annales is extremely valuable as a documentation of both ecclesiastical and political developments in 11th-century Germany, particularly on the relations between the state and the papacy (though criticized for its propapal bias). The Annales (first published in 1525) also is valued for its literary elegance and sophistication and as a primary source on the relations between the holy Roman emperor Henry IV and Pope Gregory VII.
