Zahhak in the Shahnameh — The Complete Story of Tyranny, the Serpents & Kaveh’s Resistance
The story of Zahhak (ضحاک) is one of the most powerful and enduring narratives in Ferdowsi’s Shahnameh — a moral epic that Iranians have used for a thousand years to think about power, corruption, popular resistance, and the conditions under which tyranny becomes possible. It is not simply a myth about a monster. It is a precise analysis, told through allegory and poetry, of how evil gains entry into a good person, how it grows through small compromises, and how it is ultimately — only — defeated by the courage of ordinary people who refuse to stay silent.
This guide tells the full story with depth, includes original Farsi verses from Ferdowsi’s epic, and explains the symbolism that makes this 10th-century narrative feel contemporary in every era.
Quick Answer
Who is Zahhak in the Shahnameh?
Zahhak (ضحاک) is the great tyrant of Ferdowsi’s Shahnameh — a prince who made a pact with Ahriman (the dark force) and grew two serpents from his shoulders that demanded human brains as daily food. He ruled Iran for a thousand years through fear and cruelty until Kaveh the Blacksmith (کاوه آهنگر) sparked a popular uprising and Fereydun (فریدون) defeated and imprisoned him in Mount Damavand. His story is the Shahnameh’s defining meditation on tyranny.

The Origins of Zahhak — How a Prince Became a Tyrant
Zahhak’s story does not begin with a monster. It begins with an ordinary young man — the son of a virtuous Arabian king named Mardas. Ferdowsi’s genius is to show tyranny not as an alien force that descends from outside, but as something that grows from within through a series of choices, each one seemingly small but each one opening a door to the next.
Stage 1 — Ahriman’s first approach: the murder of the father
Ahriman (اهریمن) — the principle of darkness in Zoroastrian thought — approaches the young Zahhak as a wise counsellor. He tells him that his father Mardas is old and that the kingdom would be better under his youthful energy. Step by step, through flattery and manipulation, Ahriman leads Zahhak into setting a trap that kills his own father. This is the first moral fall — not dramatic but quiet, almost reasonable-sounding at the time. Ferdowsi presents this as the mechanism of corruption: it rarely announces itself as evil.
Stage 2 — The poisoned kiss: Ahriman’s mark on Zahhak’s shoulders
After Zahhak has committed the first crime, Ahriman appears again — this time as a skilled cook who prepares increasingly elaborate feasts. He asks one reward: to kiss Zahhak’s shoulders. From those two kisses, two serpents grow — one from each shoulder. They cannot be removed. Every treatment causes them to grow back. A physician (Ahriman in disguise again) tells Zahhak the only way to quieten the serpents is to feed them human brains every day. This is the physical mark of moral corruption: visible, permanent, and insatiable.
Stage 3 — The seizure of Iran: the fall of Jamshid
Ahriman manipulates Zahhak into marching on Iran, where the once-great king Jamshid has lost legitimacy through his own arrogance. Zahhak defeats Jamshid and seizes the Peacock Throne. What began as the corruption of one young man has now become the political reality of an entire civilisation. The transition from personal moral failure to structural tyranny is complete — and Ferdowsi shows it as a natural progression rather than a sudden catastrophe.
The Serpents — What They Mean
The image of two serpents growing from Zahhak’s shoulders — one of the most immediately recognisable symbols in all of Persian literature — repays close attention. Ferdowsi was not simply inventing a grotesque image for dramatic effect.
The serpents as insatiable appetite
Two human brains per day. Every day. For a thousand years. This mathematics of cruelty is precise: the demand of the serpents is not occasional or strategic — it is structural and unending. Power that has become tyranny is not satisfied; it has to keep consuming to sustain itself. The moment it stops, it starts to weaken. Zahhak is not killing people for a reason — he is killing them to feed something that can never be full.
The serpents as the visible mark of the hidden deal
Zahhak chose power over integrity at each step. The serpents are what that choice looks like when it becomes permanent — when the transaction with darkness can no longer be hidden. Every tyrant in the Shahnameh carries a mark of their inner condition expressed outwardly. Zahhak’s mark is the most dramatic, but it follows the same logic: character becomes fate, and fate becomes visible.
The court’s complicity: the two cooks and their substitution
Two cooks in Zahhak’s kitchen — Armayil and Garmayil — discover that if they substitute sheep brains for one of the two daily human brains, the serpents cannot tell the difference. They secretly save one victim each day and send the saved people to the mountains, where they eventually become ancestors of the Kurdish people. This detail is remarkable: even within a totalitarian structure, small acts of private resistance are possible. The cooks cannot overthrow Zahhak but they can reduce harm. Ferdowsi honours this — it is not nothing.
Kaveh the Blacksmith — The Uprising That Changed Everything
Kaveh the Blacksmith (کاوه آهنگر — Kāveh-ye āhangar) is one of the great figures of world literature — not because he is powerful, wealthy, or strategically positioned, but because he is an ordinary person who reaches a breaking point and refuses to comply. His moment of refusal sets the entire resistance in motion.
The moment of Kaveh’s rebellion — in Ferdowsi’s words
بپا خاست کاوه ز پیش ضحاک
که ای شاه با تو سخن دارم پاک
Be-pā khāst Kāveh ze pish-e Zahhāk / Ke ey shāh bā to sokhan dāram pāk
“Kaveh rose before Zahhak / and said: O king, I have pure words for you.”
Kaveh’s sons and the demand
Kaveh had seventeen sons. Sixteen had already been taken to feed Zahhak’s serpents. When soldiers come to take the seventeenth — the last — Kaveh goes to Zahhak’s court to beg for his son’s life. He is given his son back, and in exchange he is asked to sign a document saying that Zahhak is a just and worthy ruler. Kaveh signs — and then, in front of the entire court, he tears the paper up. He walks out. This is the act. Not the sword. Not the uprising (that comes later). The act is the public refusal to say something he knows to be false.
The Derafsh Kaviani — the banner of freedom
Outside the palace, Kaveh takes off his leather apron — the working apron of a blacksmith — and raises it on a pole. The people follow him. This humble object becomes the first flag of resistance: the Derafsh Kaviani (درفش کاویانی) — Kaveh’s banner. It later becomes studded with jewels as Fereydun’s royal standard. But in its origin it is a blacksmith’s apron. Ferdowsi is making a deliberate point: the material of freedom is not royal — it is ordinary, it is the tool of daily work, raised in dignity.
Why Kaveh matters beyond the Shahnameh
The Derafsh Kaviani remained the royal standard of Persia for centuries after the Shahnameh. When the Sasanian dynasty fell to the Arab invasion in 651 CE, the banner was captured — its loss was considered by Iranians as significant as the fall of the empire itself. A blacksmith’s leather apron that became a national symbol: Ferdowsi understood that legitimacy in Iranian culture flows from work, justice, and courage — not from divine right or birth alone.
Fereydun — The Victor Who Did Not Kill
Fereydun (فریدون) is the hero who ultimately defeats Zahhak — but his victory is remarkable for what he chooses not to do.
Fereydun’s origin and the hidden destiny
Fereydun was hidden from Zahhak as a child — his father had been killed and his mother fled to the mountains, where he was nursed by a miraculous cow. The people’s hope was preserved secretly, fed on milk, growing in obscurity until the moment arrived. The imagery is deliberate: the legitimate ruler of Iran is not in a palace. He is in hiding, dependent on the land and on those willing to protect him.
The defeat — and the decision not to kill
When Fereydun finally defeats Zahhak in battle, he has the opportunity to kill him. An angel stops him — telling him the time for Zahhak’s death has not yet come. Instead, Fereydun chains Zahhak deep within a cave inside Mount Damavand (کوه دماوند) — the great volcanic mountain north of Tehran. The imprisonment rather than execution is theologically important: evil is not destroyed, it is contained. It can break free again if vigilance fails. The story does not end with the permanent defeat of darkness — it ends with darkness being held, requiring continued guardianship.
Fereydun’s reign: justice as the alternative
Fereydun’s rule is presented not as utopia but as the restoration of balance — a state in which justice, reason, and compassion operate instead of fear. He rules for five hundred years. His reign eventually ends in tragedy (his sons’ fratricide), showing Ferdowsi’s consistent refusal to allow permanently happy endings: good governance requires the same vigilance as the fight against tyranny.

On Zahhak’s name and shadow — Ferdowsi’s introduction
ز شاهان او بد اندر جهان نامدار
ضحاک نامش سیهروز و بدکار
Ze shāhān o bod andar jahān nāmdār / Zahhāk nāmash siyah-ruz va bad-kār
“Among kings he was famous throughout the world / His name was Zahhak — black-fated and evil-doing.”
On the serpents — the mark of corruption made visible
دو مار بُد بر دوشش ز بوس اهریمن
خورش مغز مردم بدان انجمن
Do mār bod bar dushas ze bus-e Ahriman / Khoresh maghz-e mardom bedān anjoman
“Two serpents were on his shoulders from Ahriman’s kiss / Their food was the brains of human beings.”
Kaveh’s cry — the moment of public refusal
که ای شاه داد از تو ای شهریار
ستم کم کن این بیگناهان مدار
Ke ey shāh dād az to ey shahriyār / Setam kam kon in bi-gonāhān madār
“O king, I demand justice from you, O sovereign / Reduce your oppression — do not hold the innocent.”
The Derafsh Kaviani — Kaveh’s banner raised
همان چرم کاوه که آهنگران
بپوشند پشت پا تا بر میان
بیاویخت بر نیزه کاوه بلند
درفشی برآمد جهان ارجمند
Hamān charm-e Kāveh ke āhangaran / Bepushend posht-e pā tā bar miyān / Beyāvikht bar neze Kāveh boland / Derafshi barāmad jahān arjomand
“That same leather of Kaveh that blacksmiths / wear from the back of the knee to the waist / Kaveh hung high upon a spear / And a banner rose — honoured throughout the world.”
The Symbolism of Zahhak — What Ferdowsi Was Really Saying
The mechanism of evil — small steps, not sudden catastrophe
Zahhak’s descent is gradual: first a suggestion about his father, then a poisoned kiss, then the serpents, then the seizure of power. No single step seems impossible to refuse. The lesson Ferdowsi draws is that the time to resist tyranny is early — at the first small compromise — not when the serpents are already on the shoulders and a thousand years of cruelty are underway. By then, only enormous collective courage can undo what individual small surrenders enabled.
Kaveh as the dignity of the ordinary person
Kaveh is not a general, a prince, or a wise elder. He is a blacksmith — a craftsman, a working man whose hands make things. Ferdowsi makes him the hero of the resistance because the Shahnameh consistently insists that legitimacy in Iranian culture derives from productive work and moral courage, not from bloodline or military rank. The leather apron becoming a royal banner is Ferdowsi’s clearest symbol of this value.
Mount Damavand — the contained evil
Mount Damavand (کوه دماوند) — still Iran’s highest mountain, visible from Tehran — has been associated with Zahhak’s imprisonment for a thousand years. Iranians looking at Damavand are looking at the mountain that contains their great mythological evil. The choice of imprisonment rather than execution is philosophically important: Ferdowsi does not promise the end of evil. He promises only that with courage, it can be chained. The vigilance must continue.
Ahriman and the psychology of manipulation
Ahriman never forces Zahhak. He advises, flatters, cooks fine meals, and asks only small things — until each small thing has opened a door that cannot be closed. Ferdowsi’s Ahriman is not a destroyer; he is a corruptor. He works through the target’s own desires — ambition, comfort, the wish to be told that what one wants to do is also right. This psychological precision makes the Zahhak narrative feel contemporary in every era in which it has been read.
Zahhak’s Legacy in Persian Culture
Nowruz and the defeat of darkness
The defeat of Zahhak and the beginning of Fereydun’s reign is traditionally associated with Nowruz — the Persian New Year. The overthrow of winter darkness by the light of spring carries the same symbolic register as Fereydun’s defeat of Zahhak. Both involve the end of a long dark period and the renewal of life.
In Iranian art and visual culture
Zahhak with two serpents on his shoulders is one of the most depicted images in Persian miniature painting. The Shahnameh manuscripts preserved in museums worldwide contain hundreds of illustrated Zahhak scenes — each one exploring the visual grammar of tyranny and its relationship to the human body.
In modern Iranian political discourse
The Zahhak narrative has been invoked in every major Iranian political upheaval — the Constitutional Revolution (1905–1911), the 1979 Revolution, and in contemporary protest movements. Kaveh’s leather apron and Fereydun’s victory are living cultural references, not historical footnotes.
The Zahhak myth in other traditions
The Zahhak figure — known as Aži Dahāka in the Avesta (Zoroastrian scripture) — predates Ferdowsi by millennia. Ferdowsi’s achievement was to take this ancient mythological material and retell it in a form that combined spiritual depth with political immediacy and artistic beauty.

Frequently Asked Questions About Zahhak
Who is Zahhak in the Shahnameh?
Zahhak (ضحاک) is the great tyrant of Ferdowsi’s Shahnameh — an Arabian prince who was corrupted by Ahriman (the force of darkness) and grew two serpents from his shoulders after a poisoned kiss. He seized the throne of Iran from king Jamshid and ruled for a thousand years through fear and cruelty, requiring the brains of two young men each day to feed his serpents. He is ultimately defeated by Fereydun, supported by the uprising sparked by Kaveh the Blacksmith.
What do the serpents on Zahhak’s shoulders symbolize?
The two serpents represent the insatiable hunger of power corrupted by darkness — a need that can never be satisfied and that requires constant consumption to sustain itself. They also represent the visible, physical manifestation of Zahhak’s inner corruption: the deal he made with evil cannot be hidden and cannot be removed. In psychological terms, the serpents are what happens when ambition overrides conscience — the appetite that grows from each moral compromise until it becomes uncontrollable.
Who is Kaveh the Blacksmith and what did he do?
Kaveh the Blacksmith (کاوه آهنگر) is a craftsman in Zahhak’s Iran whose sixteen sons have already been killed to feed the serpents. When soldiers come for his seventeenth son, Kaveh goes to Zahhak’s court, is given his son back, and is asked to sign a document declaring Zahhak a just ruler. He signs — then tears the paper up publicly. He walks out, raises his leather apron on a pole as a banner of resistance, and sparks the popular uprising that brings Fereydun to power. His apron becomes the Derafsh Kaviani — the royal standard of Persia.
What is the Derafsh Kaviani?
The Derafsh Kaviani (درفش کاویانی — Kaveh’s banner) is the leather apron of Kaveh the Blacksmith, raised on a spear as a symbol of resistance against Zahhak’s tyranny. It became the royal standard of successive Persian dynasties — studded with jewels and carried into battle. When the Sasanian empire fell to the Arab invasion in 651 CE, the capture of the Derafsh Kaviani was considered as significant as the fall of the throne itself. A blacksmith’s working apron became one of Iran’s most powerful national symbols.
Why does Fereydun imprison Zahhak instead of killing him?
When Fereydun defeats Zahhak, an angel stops him from delivering the killing blow — telling him the time for Zahhak’s death has not yet come. Instead Fereydun chains Zahhak deep within a cave in Mount Damavand. The theological meaning: evil is not permanently defeated — it is contained. It requires continued guardianship. The story does not end with darkness destroyed; it ends with darkness chained, and with the implication that if vigilance fails, the chains can break. Persian tradition holds that when the end of the world comes, Zahhak will break free from Damavand.
Is Zahhak originally from Arabic or Iranian mythology?
The Zahhak figure exists in both traditions. In the Avesta — the ancient Zoroastrian scriptures predating Ferdowsi by millennia — he appears as Aži Dahāka (the serpent Dahāka). Ferdowsi placed him as an Arabian king to make a cultural point: the greatest threat to Iran can come from outside. Whether this represents an Arab/Islamic conquest allegory (Ferdowsi wrote during the early Islamic period) is debated by scholars. Ferdowsi’s genius was to synthesise these pre-Islamic mythological materials into a coherent, politically resonant epic in New Persian.
