アフラ・マズダー
During the early Parthian Empire, Ahura Mazda was visually represented for worship. This practice ended during the beginning of the Sassanid empire. Zoroastrian iconoclasm, which can be traced to the end of the Parthian period and the beginning of the Sassanid, eventually put an end to the use of all images of Ahura Mazda in worship. However, Ahura Mazda continued to be symbolized by a dignified male figure, standing or on horseback which is found in Sassanian investiture.
