Manzat (Manzât), also spelled Mazzi'at, Manzi'at and Mazzêt, sometimes known by the Sumerian name Tiranna (dTIR.AN.NA) was a Mesopotamian and Elamite goddess representing the rainbow. She was also believed to be responsible for the prosperity of cities. In Elam she was worshiped in the lowlands in the proximity of Susa, especially in the area known as Hubshen, associated with the archaeological sites Deh-e Now and Tappeh Horreeye, while in Mesopotamia she was associated with Der, though there is also evidence that she was venerated in Nippur, Larsa and other cities.
