According to Plutarch[3]: 46 Zoroaster named "Areimanios" as one of the two rivals who were the artificers of good and evil. In terms of sense perception, Oromazes was to be compared with light, and Areimanios to darkness and ignorance; between these was Mithras the Mediator. Areimanios received offerings that pertained to warding off evil and mourning.
