AssianismAssianism (Уацдин) is a folk religion derived from the traditional mythology of the Ossetians, modern descendants of the Scythians of the Alan tribes, believed to be a continuation of the ancient Scythian religion. The religion is known as "Assianism" among its Russian-speaking adherents ("Assianism" means the religion of the "As" or "Oss"—an ancient name of the Alans, from which the Greeks possibly drew the name of "Asia", which is preserved in the Russian and Georgian-derived name "Ossetians"), and as Uatsdin (Уацдин), Ætsæg Din (Æцæг Дин; both meaning "True Faith"), Æss Din (Æсс Дин, Ossetian-language rendering of "Assianism"), or simply Iron Din (Ирон Дин, "Ossetian Faith") by Ossetians in their own language.
Avestan periodThe Avestan period (1500-500 BCE) is the period in the history of the Iranian peoples when the Avesta was produced. It saw important contributions to both the religious sphere, as well as to Iranian mythology and its epic tradition. Scholars can reliably distinguish between two different linguistic strata in the Avesta; Old Avestan and Young Avestan, which are interpreted as belonging to two different stages in the development of the Avestan language and society.
