Zoroaster — the Iranian prophet and founder of Mazdaism, known in his own tradition as Zarathustra — enters the depth-psychology corpus along two principal axes. The first is mythological-comparative: Joseph Campbell treats Zoroaster as a pivotal figure in the history of dualistic cosmology, charting how the prophet's vision of a universe bifurcated between Ahura Mazda and Angra Mainyu generated the cosmic-historical framework — twelve millennia of conflict culminating in the Saoshyant — that would profoundly shape Gnostic, Jewish apocalyptic, and early Christian thought. Campbell reads Zoroaster's birth as the decisive eschatological turning point built into the myth's own structure. The second axis is depth-psychological: Jung, in his Zarathustra seminars, treats the historical Zoroaster as the archetypal substrate that Nietzsche unconsciously appropriated, arguing that Nietzsche's Zarathustra recapitulates — and dangerously inflates — the profile of the ancient prophet: monotheistic reformer, opponent of magic, inaugurator of moral dualism, ultimately absorbed into the archetype of the Wise Old Man. Hans Jonas situates Iranian dualism as one of the three foundational forces shaping the Hellenistic religious world, making Zoroastrianism structurally central to any genealogy of Gnosticism. Henry Corbin, meanwhile, places Zoroaster within Suhrawardi's theosophy of light, where the prophet anchors an Ishraqiyya lineage of illuminationist wisdom. Taken together, these treatments reveal Zoroaster as an irreducible node at the intersection of eschatology, moral dualism, prophetic psychology, and the history of Light-metaphysics.
It is supposed that with the birth of Zoroaster, twelve thousand years following the creation of the world, a decisive turn was given the conflict in favor of the good
Campbell establishes Zoroaster's birth as the cosmologically decisive event within the Mazdaean dualistic scheme, making the prophet the pivotal figure in a twelve-thousand-year eschatological drama.

in the last three thousand years, following the birth of Zoroaster, the will of the other would be broken
Campbell presents the Bundahish's scheme in which Zoroaster's birth inaugurates the final eschatological epoch, situating the prophet structurally within a cosmic temporal architecture shared by Zoroastrian and later Abrahamic traditions.

The Zoroastrians had that concept of Asura, the highest god, that very ancient idea of the Rigveda, and they chose the name in the Persian form, Ahura, as an attribute for Mazda, so their god was called Ahura Mazda.
Jung traces the linguistic and conceptual genealogy of Ahura Mazda back through Vedic Asura to demonstrate the deep Indo-Iranian root of Zoroastrian theology, contextualizing Nietzsche's appropriation of Zarathustra against the historical prophet.

the beautiful monotheism of Ahura Mazda was split up into a multitude of gods, like the splitting up of God into the Trinity and then into the many saints
Jung reads the degradation of Zoroastrian monotheism into a polytheistic pantheon as a structural parallel to Christian theological development, positioning Zoroastrianism as a comparative archetype for institutional religious psychology.

this savior, like Zoroaster, descends from the sphere of Light; but, unlike Zoroaster, partakes only apparently of the nature of the world
Campbell uses Zoroaster as the comparative standard against which to measure the Gnostic-Docetic Christ, arguing that the Gnostic savior transposes the Zoroastrian Light-descent motif into a fully docetic register.

Jung's seminar index formally distinguishes the historical Zoroaster and Zoroastrianism from Nietzsche's Zarathustra, while cross-referencing their relationship to Christianity as a central analytical thread.

Jewish monotheism, Babylonian astrology, and Iranian dualism were probably the three main spiritual forces that the East contributed to the configuration of Hellenism
Jonas positions Iranian dualism — the broader tradition in which Zoroaster is the founding figure — as one of the three constitutive forces shaping the Hellenistic religious synthesis that produced Gnosticism.

In Zoroastrianism, too, a great deal of stress is placed on such concerns: next-of-kin marriage, disposal of clipped hair and fingernails, dry wood for the fire, menstrual impurity
Campbell situates Zoroastrianism alongside biblical religion as a tradition elevating tribal custom into cosmic law, while distinguishing Zoroastrianism's deeper cosmic view from the biblical Fall narrative.

Jung's index in Symbols of Transformation separately references both Zarathustra and Zoroaster, indicating that the historical prophet and Nietzsche's figure are distinguished but related in Jung's symbolic analysis.

They took over certain Persian ideas from the Zend-Avesta, particularly the hygienic rules which they applied in a more or less mechanical way, accompanied by metaphysical teaching also taken from the Zend-Avesta
Jung notes the Mazdaznan sect's appropriation of Zend-Avestan ideas in Leipzig as biographical context for Nietzsche's encounter with Zoroastrian material prior to composing Thus Spake Zarathustra.
