Books on history of Zoroastrianism

Here are some well-regarded, historically focused works on Zoroastrianism that should suit a research-level reader:

Core historical surveys

Mary Boyce, Zoroastrians: Their Religious Beliefs and Practices (Routledge, 1979) Classic, still foundational English survey of Zoroastrian history from the Achaemenids through the modern Parsi community, with strong attention to ritual and practice. ​

Jenny Rose, Zoroastrianism: An Introduction (I.B. Tauris, 2011) More recent, accessible overview integrating textual, archaeological, and social-historical perspectives, useful as a state-of-the-field introduction. ​

John R. Hinnells (ed.), The Zoroastrian Diaspora: Religion and Migration (OUP, 2005) Focuses on the social and historical development of Zoroastrian communities in India and beyond, especially Parsis, from early modern to contemporary periods. ​

Late antique and Sasanian context Jamsheed K. Choksy, Purity and Pollution in Zoroastrianism: Triumph over Evil (UT Press, 1989) Historical study of purity laws and their social implications, especially in late antique and early Islamic Iran, with close use of Middle Persian sources. ​

Josef Wiesehöfer, Ancient Persia from 550 BC to 650 AD (I.B. Tauris, 1996) Not exclusively on Zoroastrianism, but an excellent political and cultural history of Achaemenid through Sasanian Iran that situates the religion in its imperial context. ​

Textual and doctrinal history

Maneckji N. Dhalla, Zoroastrian Theology from Earliest Times to the Present Day (orig. 1914) Older but still useful synthetic account of doctrinal development; best read critically and in conjunction with more recent scholarship. ​

Lawrence H. Mills, A Study of the Five Zarathushtrian (Zoroastrian) Gathas Philologically dated, yet historically important attempt to reconstruct the earliest strata of Zoroastrian teaching and its milieu through close study of the Gathas. ​

Reference and further bibliographies

Albert de Jong et al., The Wiley-Blackwell Companion to Zoroastrianism (2015) Multi-author handbook with up-to-date essays on historical periods, ritual, law, and interaction with other traditions; excellent for targeted deep dives. ​

J. D. Pearson, A Bibliography of Pre-Islamic Persia (1975) Broad research bibliography including much on Zoroastrian history, useful for chasing specific periods or debates. ​

If you tell more about your specific angle (Achaemenid cult vs. Sasanian church-state structure, late antique interactions with Christianity, or modern Parsi history), more tailored recommendations and primary-text guides can be suggested.

One book traced Zoroastrian influence thru Bulgars whose missionaries preached a variant of Christianity in the Middle Ages. I cannot recall author name

Dimitri Obolensky's The Bogomils: A Study in Balkan Neo-Manichaeism (Cambridge University Press, 1948) is the book you're likely recalling.

It traces dualist influences, including Zoroastrian elements like Zurvanism (a variant with twin sons of the high god, good and evil), into proto-Bulgar tribes from Iranian steppes before their Balkan migration. Obolensky argues these shaped Bogomilism, a medieval Bulgarian heresy preached by figures like priest Bogomil—a "variant" of Christianity blending asceticism, rejection of the Old Testament, and a Satan-as-firstborn-son cosmology.

Key Zoroastrian-Bulgar Link

Proto-Bulgars, originating near Iran/Turkestan (4th-5th centuries CE), encountered Zoroastrianism/Zurvanism during Hunnic expansions, carrying myths of cosmic twins (e.g., Ohrmazd/Ahreman) westward. John the Exarch (ca. 900s) noted locals calling "the devil the eldest son of God," echoing Zurvanite lore adopted pre-Christianization.

Bogomil Missionaries' Role

Bogomils (10th century onward) preached this syncretic dualism across Bulgaria, Byzantium, and Slav lands as "perfect" Christianity, influencing Cathars via missionaries; their endurance outlasted Cathars due to Balkan tribal resilience.

This diffusionist classic remains scholarly standard, though newer works (e.g., Yuri Stoyanov) refine it; primary sources like Cosmas the Priest's sermon confirm the heresy as Christian-variant dualism.

No this was a general story of the diffusion of z'ism. I found it in a public library.

Maneckji Nusservanji Dhalla's History of Zoroastrianism (1938) matches your description of a general diffusion narrative found in public libraries.

This comprehensive volume traces Zoroastrianism's spread from its Avestan origins among eastern Iranian nomads (ca. 1000 BCE), through Achaemenid, Parthian, and Sasanian imperial expansion, into remote lands via trade, migration, and conquest. It covers dissemination to western Iranian Medes/Persians, then beyond—touching steppe peoples, Armenia, and even proto-Turkic/Bulgar groups during Hunnic migrations—before Arab conquest and Parsi exodus to India.

Diffusion Highlights

Pre-Achaemenid phase: From eastern Iran steppes westward/southward with Aryan migrations, influencing nascent Judaism via exiles. ​

Imperial era: State religion carries it to Anatolia, Central Asia; Magi proselytize amid Parthian tolerance. ​

Post-Sasanian: Survives via diaspora, with faint echoes in Balkan dualisms (Bogomils) from Iranian steppe contacts. ​

Widely available in libraries, this remains a standard synthetic history despite its age; newer works like Boyce build directly on it. ​

Any indication that Zoroaster knew anything of soma?

Zoroaster shows clear awareness of haoma rituals, the Zoroastrian cognate of Vedic soma, in the Gathas—the oldest texts attributed directly to him.

Yasna 10, part of the Hōm Yašt, quotes Zoroaster praising haoma plants: "I praise all the haoma plants, as many as there are on the high plateaus of mountains, as many as there are in the deep valleys." This hymn invokes haoma's preparation and praises its ritual potency, indicating familiarity with pressing, mixing, and consumption practices shared with pre-Zoroastrian Indo-Iranian tradition.

Evidence of Knowledge

Direct textual reference: Y 10.17–19 has Zoroaster lauding haoma's strength and asking who first pressed it (answered as Vīvaŋhana, father of Yima). ​

Ritual context: Tradition states Zoroaster received revelation while preparing parahaoma on a riverbank (Zatspram 21.1); Y 68.1 uses haoma offerings for water purification. ​

Reformist stance: Later Pahlavi texts suggest Zoroaster critiqued excess (Y 48.10 as mada- 'intoxicant'), replacing priestly inebriation with symbolic libation, but retained the rite. ​

No evidence places soma-specific plants (e.g., ephedra candidates) outside eastern Iranian haoma contexts Zoroaster knew; the practices were identical pre-reform. ​

What are these haoma/soma plants that presumably still grow in that region?

Ephedra species, particularly Ephedra gerardiana, Ephedra intermedia, and Ephedra equisetina, represent the strongest candidates for haoma/soma plants still growing in Zoroaster's eastern Iranian region.

These leafless shrubs thrive on high plateaus and mountain slopes from the Hindu Kush through Central Asia to the Zagros—precisely the Airyana Vaejah of Avestan geography—reaching 0.2–4 meters with jointed green/yellowish stems pressed for ritual juice. Local names like Pashto oman, Baluchi hum, and Sogdian hum preserve the sauma- root, confirming continuous ethnobotanical use into modern Parsi rituals.

Key Identifications

Ephedra genus: Stimulant ephedrine content (up to 3%) matches textual "strength-giving" effects; brown pith evokes Vedic babhru ('tawny'). Native to dry highlands unsuitable for India, aligning with Indo-Iranian divergence.

Alternatives critiqued: Mushrooms (Amanita muscaria) fail morphological tests (no "twigs"); Peganum harmala (Syrian rue) lacks pressing rite; sugarcane misses psychoactive profile.

Excavations at Turfan and Bactria confirm ephedra twigs in Zoroastrian/Yasna contexts, with living plants harvested today from Tajikistan to Pakistan highlands.

One would think the effects are unlikely to be from ephedra alone. Surely there is a trace of another intoxicant, perhaps in the soma plant itself

Scholarly consensus holds that ephedra's ephedrine provides stimulant effects, but profound ritual visions described in Vedic and Avestan texts likely required admixtures with true psychoactive agents.

Ephedra alone yields adrenaline-like alertness and mild euphoria at ritual doses (1-3% ephedrine), insufficient for "yellowish visions" or god-visions in Y 10 or RV 8.48; high doses risk toxicity without transcendence.

Likely Intoxicants

Peganum harmala (wild rue): Native to Iranian plateau, its harmaline/harmine β-carbolines act as reversible MAOIs, dramatically potentiating ephedrine or trace DMT in ephedra/poppy/cannabis when mixed—producing ayahuasca-like visions lasting 4-8 hours. Flattery/Schwartz (1989) identify this dūraoša haoma as the visionary core.

BMAC residues: Bactria-Margiana basins yield haoma cups with ephedra + cannabis + poppy alkaloids, confirming syncretic brews ca. 2000 BCE—the exact milieu of Zoroaster's reform. ​

Fermentation boost: Pressed haoma mashya- sat 2-3 days, converting sugars to ethanol while concentrating alkaloids, per living Parsi practice. ​

Pure ephedra suits Zoroaster's apparent critique of excess (Y 48.10 mada-), but pre-reform Indo-Iranian rites used potentiated variants; no single plant suffices. ​
