Zurvanism - The "twin Brother" Doctrine

The "twin Brother" Doctrine

"Classical Zurvanism" is the term coined by Zaehner (1955, intro) to denote the movement to explain the inconsistency of Zoroaster's description of the 'twin spirits' as they appear in Yasna 30.3-5 of the Avesta. According to Zaehner, this "Zurvanism proper" was "genuinely Iranian and Zoroastrian in that it sought to clarify the enigma of the twin spirits that Zoroaster left unsolved." (Zaehner, 1961)

As the priesthood sought to explain it, if the Malevolent Spirit (lit: Angra Mainyu) and the Benevolent Spirit (Spenta Mainyu, identified with Ahura Mazda) were twins, then they must have had a "father", who must have existed before them. The priesthood settled on Zurvan - the hypostasis of (Infinite) Time - as being "the only possible 'Absolute' from whom the twins could proceed" and which was the source of good in the one and the source of evil in the other (Zaehner, 1961).

The Zurvanite "twin brother" doctrine is also evident in Zurvanism's cosmogonical creation myth, that in its "classic" form, does not contradict the Mazdean model of the origin and evolution of the universe, which begins where the Zurvanite model ends. It may well be (as proposed by Cumont and Schaeder) that the Zurvanite cosmogony was an adaptation of an antecedent Hellenic Chronos cosmogony that portrayed Infinite Time as the "Father of Time" (not to be confused with Cronus, a Titan and father of Zeus) whom the Greeks equated with Oromasdes, i.e. Ohrmuzd/Ahura Mazda.

The "classic" Zurvanite model of creation, preserved only by non-Zoroastrian sources, proceeds as follows: In the beginning, the great God Zurvan existed alone. Desiring offspring that would create 'heaven and hell and everything in between,' Zurvan sacrificed for a thousand years. Towards the end of this period, androgyne Zurvan began to doubt the efficacy of sacrifice and in the moment of this doubt Ohrmuzd and Ahriman were conceived: Ohrmuzd for the sacrifice and Ahriman for the doubt. Upon realizing that twins were to be born, Zurvan resolved to grant the first-born sovereignty over creation. Ohrmuzd perceived Zurvan's decision, which He then communicated to His brother. Ahriman then preempted Ohrmuzd by ripping open the womb to emerge first. Reminded of the resolution to grant Ahriman sovereignty, Zurvan conceded, but limited kingship to a period of 9000 years, after which Ohrmuzd would rule for all eternity (Zaehner, 1955:419-428).

Christian and Manichean missionaries considered this doctrine to be exemplary of the Zoroastrian faith and it was these and similar texts that first reached the west. Corroborated by Anquetil-Duperron's "erroneous rendering" of Vendidad 19.9, these led to the late 18th century conclusion that Infinite Time was the first Principle of Zoroastrianism and Ohrmuzd was therefore only "the derivative and secondary character." Ironically, the fact that no Zoroastrian texts contained any hint of the born-of-Zurvan doctrine was considered to be evidence of a latter-day corruption of the original principles. The opinion that Zoroastrianism was so severely dualistic that it was, in fact, ditheistic or even tritheistic would be widely held until the late 19th century (Dhalla, 1932:490-492; cf. Boyce, 2002:687).
