Then it occurred to Zál that Rustem, after such an achievement, would be a proper person to take vengeance on the enemies of his grandfather Narímán, who was sent by Feridún with a large army against an enchanted fort situated upon the mountain Sipund, and who whilst endeavoring to effect his object, was killed by a piece of rock thrown down from above by the besieged. The fort[7], which was many miles high, inclosed beautiful lawns of the freshest verdure, and delightful gardens abounding with fruit and flowers; it was also full of treasure. Sám, on hearing of the fate of his father, was deeply afflicted, and in a short time proceeded against the fort himself; but he was surrounded by a trackless desert. He knew not what course to pursue; not a being was ever seen to enter or come out of the gates, and, after spending months and years in fruitless endeavors, he was compelled to retire from the appalling enterprise in despair. "Now," said Zál to Rustem, "the time is come, and the remedy is at hand; thou art yet unknown, and may easily accomplish our purpose." Rustem agreed to the proposed adventure, and according to his father's advice, assumed the dress and character of a salt-merchant, prepared a caravan of camels, and secreted arms for himself and companions among the loads of salt. Everything being ready they set off, and it was not long before they reached the fort on the mountain Sipund. Salt being a precious article, and much wanted, as soon as the garrison knew that it was for sale, the gates were opened; and then was Rustem seen, together with his warriors, surrounded by men, women, and children, anxiously making their purchases, some giving clothes in exchange, some gold, and some silver, without fear or suspicion. But when the night came on, and it was dark, Rustem impatient drew his warriors forth, And moved towards the mansion of the chief-- But not unheard. The unaccustomed noise, Announcing warlike menace and attack, Awoke the Kotwál, who sprung up to meet The peril threatened by the invading foe. Rustem meanwhile uplifts his ponderous mace, And cleaves his head, and scatters on the ground The reeking brains. And now the garrison Are on the alert, all hastening to the spot Where battle rages; midst the deepened gloom Flash sparkling swords, which show the crimson earth Bright as the ruby.
