Angra Mainyu
Also known as: Ahriman, Ahreman, the Hostile Spirit
Mythological Narrative
Angra Mainyu, Avestan for "destructive spirit," called Ahriman in Middle Persian, is the evil pole of Zoroastrian dualism. Yasna 30 describes the two primal spirits as twins who chose opposite paths in thought, word, and deed, one choosing truth and the other the lie. He cannot create life, only counter-create: the first chapter of the Vendidad lists sixteen good lands made by Ahura Mazda, and for each Angra Mainyu casts a matching plague — killing winter, serpents, pestilence, doubt, and lamentation. Snakes, scorpions, and other noxious creatures, the khrafstras, are counted among his works.
The Bundahishn narrates his great assault: leaping from the northern darkness, he pierced the sky, burst into the earth, turned sweet water salt, withered the plants, slew the primordial bull and Gayomard the first man, and brought death to every living thing — only to find himself trapped inside the world like a beast in a snare, so that cosmic history becomes the long process of exhausting him. Doctrine promises that at the Frashokereti, the final renovation, the dead will rise, molten metal will wash the earth clean, and Angra Mainyu will be rendered powerless forever. The Zoroastrian duties of killing vermin and keeping fire and water pure are concrete acts of enlistment on the side of light. In later Persian literature Ahriman became a byword for every tempter; the devil Eblis who seduces Zahhak in the Shahnameh carries on his role.
Scholarly Commentary & Evolution
## The counter-creator
The opening chapter of the Vendidad lists sixteen good lands created by Ahura Mazda and, against each, a plague created by Angra Mainyu, 'who is all death': the serpent and winter, the locust, plunder, doubt, witchcraft, and more. The pattern of creation and counter-creation is the core of his character: he makes nothing good, only corruption of what is good.
## In the Gathas and after
The Gathas speak of two primal spirits, one more beneficent and one hostile, and of the choice every being makes between them; they do not describe the Hostile Spirit in narrative detail. The Middle Persian books of the ninth century develop Ahriman into a cosmic adversary: dwelling in endless darkness, he attacks Ohrmazd's creation, breaks through the sky, kills the first man Gayomard and the primordial bull, and fills the world with noxious creatures, beginning the mixed age of good and evil in which humanity now lives. At the end, he will be defeated and rendered powerless.
## Not worshipped
Angra Mainyu is not a god who received worship; Zoroastrian practice aims to repel him, through truthfulness, purity laws, and the destruction of creatures regarded as his. The Sasanian-era Zurvanite current made him Ohrmazd's twin brother, born of Zurvan's doubt, a view rejected by later orthodoxy.
