The Azelin chandelier 1018 A.D is a Romanesque wheel chandelier, made in the 11th century for the Hildesheim Cathedral in Hildesheim, Germany, a UNESCO World Cultural Heritage site since 1985. It is the oldest of four extant wheel chandeliers from that period, along with the Hezilo chandelier, also in Hildesheim, the Barbarossa chandelier in the Aachen Cathedral, and the Hartwig chandelier in the Abbey of Comburg. It was believed to be donated by Bishop Azelin, however his predecessor Thietmar is more likely to be the patron. Therefore, the chandelier is also called the Thietmar chandelier (Thietmarleuchter).

The Hezilo chandelier is an 11th-century Romanesque wheel chandelier. It is part of the treasures of the Hildesheim Cathedral in Hildesheim, Germany, which has been a UNESCO World Cultural Heritage site since 1985. The chandelier was most likely commissioned by Bishop Hezilo of Hildesheim, who rebuilt the cathedral after a fire. He probably also influenced the program of imagery and inscriptions. It is the largest of four extant wheel chandeliers of the period; the others surviving examples are the Azelin chandelier, the Barbarossa chandelier in the Aachen Cathedral, and the Hartwig chandelier in the Abbey of Comburg.
