Shah Nameh/Tahúmers

This sovereign was also called Díw-bund, or the Binder of Demons. He assembled together all the wise men in his dominions, to consider and deliberate upon whatever might be of utility and advantage to the people of God. In his days wool was spun and woven, and garments and carpets manufactured, and various animals, such as panthers, falcons, hawks, and syagoshes, were tamed, and taught to assist in the sports of the field. Tahmúres had also a vizir, renowned for his wisdom and understanding. Having one day charmed a Demon into his power by philters and magic, he conveyed him to Tahmúres; upon which, the brethren and allies of the prisoner, feeling ashamed and degraded by the insult, collected an army, and went to war against the king. Tahmúres was equally in wrath when he heard of these hostile proceedings, and having also gathered together an army on his part, presented himself before the enemy. The name of the leader of the Demons was Ghú. On one side the force consisted of fire, and smoke, and Demons; on the other, brave and magnanimous warriors. Tahmúres lifted his mace, as soon as he was opposed to the enemy, and giving Ghú a blow on the head, killed him on the spot. The other Demons being taken prisoners, he ordered them to be destroyed; but they petitioned for mercy, promising, if their lives were spared, that they would teach him a wonderful art. Tahúmers assented, and they immediately brought their books, and pens and ink, and instructed him how to read and write.

  They taught him letters, and his eager mind
  With learning was illumined. The world was blest
  With quiet and repose, Peris and Demons
  Submitting to his will.

The reign of Tahmúres lasted thirty years, and after him the monarchy descended to Jemshíd, his son.
