Wheel chandelier in the context of "Chandelier"

Hildesheim Cathedral (German: Hildesheimer Dom), officially the Cathedral of the Assumption of Mary (German: Hohe Domkirche St. Mariä Himmelfahrt) or simply St. Mary's Cathedral (German: Mariendom), is a medieval Roman Catholic cathedral in the city centre of Hildesheim in Lower Saxony, Germany, that serves as the seat of the Diocese of Hildesheim. The cathedral has been on the UNESCO World Cultural Heritage list since 1985, together with the nearby St. Michael's Church because of its unique art and outstanding Romanesque architecture.

The cathedral church was built between 1010 and 1020 in the Romanesque style. It follows a symmetrical plan with two apses, that is characteristic of Ottonian Romanesque architecture in Old Saxony. The cathedral's treasures include world-famous artworks, bronze works from the time of Bishop Bernward, Bernward Doors and Bernward Column, as well as two of the four notable Romanesque wheel chandeliers: the Hezilo chandelier and the Azelin chandelier.

The Hezilo chandelier (German: Heziloleuchter) 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 (also in Hildesheim), the Barbarossa chandelier in the Aachen Cathedral, and the Hartwig chandelier in the Abbey of Comburg.

During the restoration of the cathedral (from 2010 to 2014), the chandelier was installed in St. Godehard, a basilica since 1963 and the temporary bishop's seat. After the restoration of the cathedral, which reopened on 15 August 2014, it was returned to its original location in the cathedral's nave.

The Azelin chandelier 1018 A.D (German: Azelinleuchter) 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).

Azelin (before 1000 – 8 March 1054) was Bishop of Hildesheim from 1044 until 1054.

Azelin's origin is not known. He was appointed Bishop of Hildesheim by Emperor Henry III, succeeding Thietmar. During his tenure, the cathedral built by Altfrid was destroyed by a fire on 23 March 1046, along with works of art and documents. Azelin's plans to build a new cathedral were not successful. The wheel chandelier known by his name as the Azelin chandelier was possibly donated by Thietmar.
