Adelog of Hildesheim

Adelog von Dorstadt (died 20 September 1190) was Bishop of Hildesheim from 1171 until his death.

[1] Born into a Saxon noble family, he was a relative of the Lords of Dorstadt.

In the fierce Hohenstaufen–Welf dispute between Frederick Barbarossa and the Saxon duke Henry the Lion, Bishop Adelog acted cautiously and eventually sided with the emperor.

Despite the tensions with the House of Welf, he also worked as diocesan bishop in the residence of Brunswick.

He also sponsored construction of the Our Lady Altar in Brunswick Cathedral, which he consecrated on 8 September 1188 in the presence of Henry the Lion, and in 1189 he confirmed and privileged the foundation of an Augustinian nunnery in Dorstadt.
