The notion that Zoroastrian monotheism influenced the Old Testament authors is a very widespread idea. It is an attractive idea because it fits so well with the theory that the Torah was compiled during the Persian period. It is also evident that Jews held the most famous Achaemenid kings, Cyrus and Darius, in high regard and there is a lot of evidence of Persian influences in Judaism; so, the influence of Zoroastrianism was very plausible. However, the theory of the monotheistic influence of Zoroastrianism on Judaism during the period of the Achaemenid kings breaks down on closer examination. But, the story of how this became such a pervasive idea illuminates some of the biggest problems in how history was created over the last 100 or so years. As usual, it was a story shaped by political ambition and blind acceptance of religious traditions, rather than an honest look at the evidence.

The problem with understanding the development of Zoroastrianism began in the 19th century with the scholarly acceptance of Zoroaster as the prophet who began the religion. The most prominent western scholars thought it preposterous to question the existence of the prophet (Skjærvo̵ 1997). The only question they debated was when Zoroaster lived. This question continues to be debated and the dates range wildly between 1200 BCE to 600 BCE. However, there is simply no evidence that Zoroaster was a real person and the claims that he existed are from centuries after his supposed life. As with all other legendary prophets, it is plausible that there was some guy named Zoroaster; but, his existence is unnecessary for explaining the origin of the faith.

The early archaeological work in Iran seemed to point to very early evidence of Zoroastrianism. But, the interpretation of that evidence was extremely influenced by the political climate in Iran during the 20th century, under the rule of the shahs. Reza Kahn was not a very religious person; but, he promoted nationalism in Iran to glorify and legitimize his rule. (Abdi 2001) As the preferred ruler of Iran by western countries, western scholars had little interest in questioning his promotion of a national history of Iran that glorified Zoroaster and undermined Islam. The Iranian government and western governments, particularly the British, were happy with the overt nationalism promoted through archaeology in Iran. So, even school children in America learned that Zoroastrianism was the first monotheistic religion.

Recent reexamination of the archaeological evidence claimed as demonstrating proto-Zoroastrian religious practices shows the flaws in the earlier theory. Sites interpreted as Zoroastrian fire temples are now understood as simply being rather typical pagan temples of the time and not as evidence of monotheism (Shenkar 2007). The earlier notion that Zoroastrian monotheism was “corrupted” with polytheistic influences from the Elamites and Mesopotamians no longer makes sense. It is evident that Zoroastrianism evolved from polytheistic beliefs, in much the same way as monotheism evolved across West Asia and along the same time line. The Zoroastrian texts were first compiled under the Sasanians during the 3rd century CE, when the kings were instituting theocratic government (Daryaee 1995). Just as the Roman emperors found monotheism to be politically useful, the Sasanians promoted the trend in Zoroastrianism.

This short summary of how the history of Zoroastrianism developed demonstrates that no history can simply be read and accepted at face value, particularly when it is a history of a religion. Religious histories are always three dimensional, influenced by both ancient and modern political factors.

I was inspired to write this article by a question that came up during my radio interview with Brian Magee on the Appreciate Your Mind program on KNDS, 96.3 FM in Fargo, ND. I give some other reasons for why the Zoroastrian monotheism was an unlikely inspiration for the Old Testament authors during the interview, as well as discuss a number of other issues.

Ah! I did make this too brief. What I discussed during the interview was that the Achaemenids were not monotheistic and there really isn't any evidence of monotheistic Zoroastrianism from the Persian period. Zoroastrianism hardly could have influenced Jewish monotheism during the Persian period, if monotheistic Zoroastrianism did not exist at that time. Since the temples have been reinterpreted, there is not any evidence of early monotheism in Persia. The legend of Zoroaster is based purely on interpretation of the text. The oldest existing text is from the 13th century CE. During the third century CE, the Sasanians sponsored a written corpus of texts, based on oral traditions. The dating of Zoroaster by modern scholars, based on their dating of oral traditions, based on a 13th century CE written text, is an extraordinarily speculative endeavor.

Doone - The God Checker site is really fun. Thank you.

Your post about Zurvanism highlights the complexity of defining religions. Theology is so time and location sensitive. I get really suspicious when a religious tradition claims that the history of their cult was radically different from their closest neighbors. It looks to me that cults of any region follow the same trends in theological changes over time. I think it is more rational to see monotheism as a trend, beginning primarily during the Hellenistic period and spreading through out the cults of the region, rather than to define it as an invention of any particular prophet or ethnic group.
