Arimanius (Greek: Αρειμάνιος; Latin: Arīmanius) is a name for an obscure deity found in a few Greek literary texts and five Latin inscriptions supposed to be the counterpart of Oromazes (Greek: Ὡρομάζης), the god of light. In classic texts, in the context of Zoroastrianism, Areimanios (with variations) fairly clearly refers to the Greeks' and Romans' interpretation of the Persian Ahriman.The Latin inscriptions which were found in a Mithraic context suggest a re-defined or different deity with a near-identical name.
