Zoroastrianism in the Sassanid Empire

The Sasanians ruled from 224 to 651 CE across Iran and much of western Asia. Zoroastrian worship linked royal patronage to priestly offices, sacred fires and legal foundations. Inscriptions record particular kings and priests; religious and legal books preserve teachings that were recited, interpreted and later written down.

Cosmic order and theological interpretations

Zoroastrian teaching named Ahura Mazda as the wise lord; in Middle Persian he was called Ohrmazd. Angra Mainyu, known in Middle Persian as Ahriman, represented destructive evil. Zoroastrian ethics made human choice practical: good thoughts, truthful words and good actions aligned a person with the good creation, while harmful conduct supported its destruction. Middle Persian cosmology treated fire, water and earth as good creations to be kept pure; ritual cleansing helped remove defilement caused by Angra Mainyu.

One account of creation gave Zurvan, or Time, a role as father of Ohrmazd and Ahriman. The story appears in Armenian, Syriac, Greek and Arabic reports; a fifth-century Armenian account places it in religious discussion around the Sasanian court.

Kings, sacred fires and temple service

Shapur I, who ruled from 240 to 270 CE, described himself as a Mazda worshipper in an inscription at the Ka’ba-ye Zartosht monument at Naqsh-e Rustam in Fars, southwestern Iran. He named a sacred fire for his own soul and fires for his daughter and each of his three sons. The inscription says that the endowments and obligations were written in a guarantee. It records daily offerings of a lamb, one and a half measures of bread and four measures of wine for the royal fires and named relatives and forebears. Maria Macuch interprets the thousand lambs assigned to the fires as yearly surplus from their endowed property. The arrangement linked land and produce to recurring worship, including fires and continuing provisions for services.

Coins made the royal fire visible beyond a particular temple. The fire of each king was kindled at accession, and later coins placed the regnal year beside the image of the fire. The phrase “year of the sacred fire” therefore dated the king’s reign as well as presenting him as a worshipper.

A typical small fire temple had a domed chamber, or gombad, where the sacred fire was established. Four corner pillars supported the dome on squinches, small arches spanning the square corners to form a base for the dome. A passageway around the chamber allowed priests and worshippers access, while nearby rooms held firewood, incense and ritual utensils. Priests tended the fire; ceremonies were performed in a separate yazišn-gāh, or ritual room, rather than inside the fire chamber.

The Sasanian shrine of Adur Gushnasp, traditionally associated with the warrior estate, stood at Takht-e Soleyman in Azerbaijan, in northwestern Iran. The other two celebrated fires, Adur Farnbag and Adur Burzen-Mihr, are associated in later tradition with Fars and Parthia, but their exact sites are not securely identified.

Priests and the career of Kartir

A hērbed was a priestly teacher. In the Avestan section of the Hērbedestān, a student of sacred-text recitation was expected to study for three years, ideally with three teachers, and the teacher shared responsibility for errors in recitation. By Sasanian times, hērbed had broadened into a title for learned priests. They probably taught advanced subjects such as the Middle Persian translation and interpretation of the Avesta; families may have taught recitation at home. A mōbed was a senior priestly title.

Kartir, a prominent priest of the second half of the third century, shows how a priest could exercise authority beyond ritual. In his own inscriptions, he says Shapur I appointed him over the priestly order at court and across the empire and entrusted him with religious documents and endowment deeds. He later calls himself judge of the whole empire and custodian of the Fire Temple of Anahid at Istakhr, an ancient city in Fars, southwestern Iran. These are claims in Kartir’s inscriptions, connecting one priest’s learning with court administration, religious property and judicial office.

Reciting, translating and writing the Avesta

The Avesta is a collection of sacred texts in Avestan, an Old Iranian language. Its earliest transmission was oral: priests memorized passages and taught the words through careful recitation. Zand means the translation and commentary in Middle Persian, often called Pahlavi in its written form, which helped explain Avestan wording to later readers. Some Middle Persian manuscripts place the translation between the Avestan sentences and add short glosses, so a student could follow the sacred text and its explanation together. Sasanian translation schools preserved differing interpretations, and the commentaries refer to earlier authorities as they explain disputed passages.

The Avestan alphabet was designed to record details of recitation precisely. A canon is an authorized collection of sacred writings. Jean Kellens presents a proposal that the Sasanian canon was written in the fourth century under Shapur II. Alberto Cantera instead links the recording of Avestan with translation and canonization, and argues that this process may have continued into the sixth century. These are differing scholarly chronologies. The Denkard and Bundahishn, major Middle Persian (Pahlavi) religious compilations, were assembled in the ninth and tenth centuries and preserve older material alongside the concerns of later Zoroastrian communities.

Law, property and continuing services

A late Sasanian legal compilation, the Hazār dādestān (“A Thousand Judgements”), was assembled in the first half of the seventh century. It is a collection of actual and hypothetical case histories drawn from court records, testaments, legal works and jurists’ commentaries, rather than a code arranged as a complete list of rules. Its cases cover contracts, guardianship, inheritance and disputes over religious foundations.

A ruwānagān was a pious endowment established to benefit the soul of a deceased person. Founders could dedicate land, vineyards, orchards or cattle, then name a trustee to administer it. The principal property was to remain intact; its income paid taxes, upkeep and the trustee’s work before covering the specified purpose, such as offerings, rites for the dead or alms for the poor. Founders could keep control of the foundation in their family or appoint a different guardian. Shapur’s written guarantee and the legal cases about who could manage a foundation show how ritual obligations depended on property that had to be preserved and administered.
