Hezilo of Hildesheim (c. 1012 – 5 October 1079) was a medieval German prelate who served as the bishop of the Diocese of Hildesheim from 1054 until his death in 1079. His episcopate is noted for substantial building projects, the promotion of ecclesiastical reform, and involvement in the political conflicts of the Investiture Controversy.
Early life and background
Hezilo was born into a noble family in the Saxon region of the Holy Roman Empire, most likely around 1012. Contemporary records identify him as the son of Otto of Hildesheim, a member of the local aristocracy. Before his election as bishop, Hezilo held the office of provost (propst) at the cathedral chapter of Hildesheim, a position that gave him experience in the administration of the diocese.
Election and consecration
Following the death of Bishop Gotthard of Hildesheim in 1054, Hezilo was elected by the cathedral chapter and confirmed by King Henry IV of Germany. He received episcopal consecration later that year, assuming spiritual and temporal authority over the diocese.
Episcopal activities
-
Architectural patronage – Hezilo initiated a major reconstruction of Hildesheim Cathedral (St. Mary’s) and the associated St. Michael’s Church. His most famous contribution is the bronze chandelier known as the “Hezilo chandelier,” created between 1060 and 1065 and still displayed in the cathedral. The chandelier exemplifies the high artistic standards of the Ottonian and early Romanesque periods.
-
Monastic reform – Hezilo supported the reform of monastic life within his diocese, encouraging adherence to the Benedictine Rule and fostering ties with the Cluniac movement. He granted privileges to several monasteries, including St. Magdalen’s Abbey in Hildesheim.
-
Political involvement – As a bishop within the Holy Roman Empire, Hezilo participated in imperial councils and was a supporter of King Henry IV during the early phases of the Investiture Controversy. He is recorded as having attended the Imperial Diet of Augsburg in 1077, where he sided with the imperial position against papal claims to investiture authority.
-
Legal and fiscal administration – Hezilo issued a series of charters that clarified the diocese’s rights over lands, tithes, and judicial matters. These documents contribute to modern understanding of 11th‑century ecclesiastical governance in Saxony.
Death and burial
Hezilo died on 5 October 1079. His remains were interred in Hildesheim Cathedral, where a modest tomb slab marks his burial site. Later medieval sources commemorate his contributions to the cathedral’s architecture and to the diocese’s spiritual life.
Legacy
Hezilo is remembered primarily for his architectural patronage, especially the Hezilo chandelier, which remains a key example of medieval metalwork. His episcopate reflects the broader trends of church reform and imperial‑ecclesiastical relations during the mid‑11th century. Modern historiography cites him as a representative figure of Saxon bishops who balanced local pastoral duties with the demands of imperial politics.
