The Adder demon has been universal. Herodotus relates that from a monster, half-woman, half-serpent, sprang the Scythians, and the fable has often been remembered in the history of the Turks. The 'Zohák' of Firdusi is the Iranian form of Ahi. The name is the Arabicised form of the 'Azhi Daháka' of the Avesta, the 'baneful serpent' vanquished by Thraêtaono (Traitana of the Vedas), and this Iranian name again (Dásaka) is Ahi. The name reappears in the Median Astyages. [235] Zohák is represented as having two serpents growing out of his shoulders, which the late Professor Wilson supposed might have been suggested by a phrase in the Kankato na (ye ansyá ye angyáh) which he translates, 'Those who move with their shoulders, those who move with their bodies,' which, however, may mean 'those produced on the shoulders, biting with them,' and 'might furnish those who seek for analogies between Iranian and Indian legends with a parallel in the story of Zohák.' The legend alluded to is a favourite one in Persia, where it is used to point a moral, as in the instruction of the learned Saib to the Prince, his pupil. Saib related to the boy the story of King Zohák, to whom a magician came, and, breathing on him, caused two serpents to come forth from the region of his breast, and told him they would bring him great glory and pleasure, provided he would feed these serpents with the poorest of his subjects. This Zohák did; and he had great pleasure and wealth until his subjects revolted and shut the King up in a cavern where he became himself a prey to the two serpents. The young Prince to whom this legend was related was filled with horror, and begged Saib to tell him a pleasanter one. The teacher then related that a young Sultan placed his confidence in an artful courtier who filled his mind with false notions of greatness and happiness, and introduced into his heart Pride and Voluptuousness. To those two passions the young Sultan sacrificed the interests of his kingdom, until his subjects banished him; but his Pride and Voluptuousness remained in him, and, unable to gratify them in his exile, he died of rage and despair. The prince-pupil said, 'I like this story better than the other.' 'And yet,' said Saib, 'it is the same.'
