Tabari says that the king bore on his shoulders two frightful ulcers or cancers, resembling serpents’ heads, sent him by God as a punishment for his crimes. These cancers caused him such acute agony, that he shrieked night and day. No one was able to provide a remedy or to abate the torment. One night when he was asleep, some one appeared to him in a dream, and said, “If you desire your ulcers to give less pain, apply to them human brains.” Next day, Dhohak awoke and ordered two men to be brought before him; he slew them, cut open their skulls, extracted the brains and applied them to his cancers. The relief was instantaneous, and Dhohak felt, for the first time for many days, some hours of repose. After this, every day two men were killed to form poultices for his ulcers. During the two hundred latter years of the life of Dhohak, the prisons were emptied to satisfy his requirement for fresh brains; and when no more criminals could be procured, it was made a tribute for his kingdom to render to him two men, each day, to be immolated to soothe his pain. Now there was at Ispahan a blacksmith, named Kaveh, who had two beautiful sons, whom he loved more dearly than his own life. One day they were seized, carried before the king, and his shoulders were poulticed with their brains. Kaveh was at work at his anvil when the news of the slaying of his sons reached him. He deserted his anvil; and uttering a piercing cry, he rushed into the streets, with his leathern apron before him, bitterly lamenting his loss, and calling for vengeance on the monarch. The people crowded about him, they plucked off his leather apron, and converted it into a standard. The crowd gathered as it advanced. From every street men flowed to join the army, and shortly the blacksmith found himself at the head of a hundred thousand men. They marched to Demavend, where was the palace of the tyrant. And Kaveh, before attacking it, thus addressed his soldiers, “I am not one to lead you against a king; you need a king to make war against a king.” “Well,” said his followers, “we elect you to be our king.” “I am but a simple blacksmith, and am not fit to rule,” answered Kaveh, “but there is a royal prince named Afridoun, the son of Djemschid, who has fled from the cruelty of Dhohak: choose him.” They agreed. The prince was found and invested with the sovereignty; then a battle was fought, and Dhohak’s army was routed, and the tyrant was slain. When Afridoun mounted the throne, he named Kaveh governor of Ispahan. And when Kaveh was dead, the king asked his children to give him their father’s leathern apron. Then, having obtained it, he placed it among his treasures, and whenever he went to battle he attached the smith’s apron to a tall staff, and marched under that banner against his enemies.
