The monarch immediately ascended his throne surrounded by all his warriors, and seven days were spent in mutual congratulations and rejoicing. On the eighth day they all resumed the saddle, and proceeded to complete the destruction of the enemy. They set fire to the city, and burnt it to the ground, and committed such horrid carnage among the remaining magicians that streams of loathsome blood crimsoned all the place.
Káús afterwards sent Ferhád as an ambassador to the king of Mázinderán, suggesting to him the expediency of submission, and representing to him the terrible fall of Arzang, and of the White Demon with all his host, as a warning against resistance to the valor of Rustem. But when the king of Mázinderán heard from Ferhád the purpose of his embassy, he expressed great astonishment, and replied that he himself was superior in all respects to Káús; that his empire was more extensive, and his warriors more numerous and brave. "Have I not," said he, "a hundred war-elephants, and Káús not one? Wherever I move, conquest marks my way; why then should I fear the sovereign of Persia? Why should I submit to him?"
This haughty tone made a deep impression upon Ferhád, who returning quickly, told Káús of the proud bearing and fancied power of the ruler of Mázinderán. Rustem was immediately sent for; and so indignant was he on hearing the tidings, that "every hair on his body started up like a spear," and he proposed to go himself with a second dispatch. The king was too much pleased to refuse, and another letter was written more urgent than the first, threatening the enemy to hang up his severed head on the walls of his own fort, if he persisted in his contumacy and scorn of the offer made.
As soon as Rustem had come within a short distance of the court of the king of Mázinderán, accounts reached his majesty of the approach of another ambassador, when a deputation of warriors was sent to receive him. Rustem observing them, and being in sight of the hostile army, with a view to show his strength, tore up a large tree on the road by the roots, and dexterously wielded it in his hand like a spear. Tilting onwards, he flung it down before the wondering enemy, and one of the chiefs then thought it incumbent upon him to display his own prowess. He advanced, and offered to grasp hands with Rustem: they met; but the gripe of the champion was so excruciating that the sinews of his adversary cracked, and in agony he fell from his horse. Intelligence of this discomfiture was instantly conveyed to the king, who then summoned his most valiant and renowned chieftain, Kálahúr, and directed him to go and punish, signally, the warrior who had thus presumed to triumph over one of his heroes. Accordingly Kálahúr appeared, and boastingly stretched out his hand, which Rustem wrung with such grinding force, that the very nails dropped off, and blood started from his body. This was enough, and Kálahúr hastily returned to the king, and anxiously recommended him to submit to terms, as it would be in vain to oppose such invincible strength. The king was both grieved and angry at this situation of affairs, and invited the ambassador to his presence. After inquiring respecting Káús and the Persian army, he said:
"And thou art Rustem, clothed with mighty power,
Who slaughtered the White Demon, and now comest
To crush the monarch of Mázinderán!"
"No!" said the champion, "I am but his servant,
And even unworthy of that noble station;
My master being a warrior, the most valiant
That ever graced the world since time began.
Nothing am I; but what doth he resemble!
What is a lion, elephant, or demon!
Engaged in fight, he is himself a host!"
The ambassador then tried to convince the king of the folly of resistance, and of his certain defeat if he continued to defy the power of Káús and the bravery of Rustem; but the effort was fruitless, and both states prepared for battle.
The engagement which ensued was obstinate and sanguinary, and after seven days of hard fighting, neither army was victorious, neither defeated. Afflicted at this want of success, Káús grovelled in the dust, and prayed fervently to the Almighty to give him the triumph. He addressed all his warriors, one by one, and urged them to increased exertions; and on the eighth day, when the battle was renewed, prodigies of valor were performed. Rustem singled out, and encountered the king of Mázinderán, and fiercely they fought together with sword and javelin; but suddenly, just as he was rushing on with overwhelming force, his adversary, by his magic art, transformed himself into a stony rock. Rustem and the Persian warriors were all amazement. The fight had been suspended for some time, when Káús came forward to inquire the cause; and hearing with astonishment of the transformation, ordered his soldiers to drag the enchanted mass towards his own tent; but all the strength that could be applied was unequal to move so great a weight, till Rustem set himself to the task, and amidst the wondering army, lifted up the rock and conveyed it to the appointed place. He then addressed the work of sorcery, and said: "If thou dost not resume thy original shape, I will instantly break thee, flinty-rock as thou now art, into atoms, and scatter thee in the dust." The magician-king was alarmed by this threat, and reappeared in his own form, and then Rustem, seizing his hand, brought him to Káús, who, as a punishment for his wickedness and atrocity, ordered him to be slain, and his body to be cut into a thousand pieces! The wealth of the country was immediately afterwards secured; and at the recommendation of Rustem, Aúlád was appointed governor of Mázinderán. After the usual thanksgivings and rejoicings on account of the victory, Káús and his warriors returned to Persia, where splendid honors and rewards were bestowed on every soldier for his heroic services. Rustem having received the highest acknowledgments of his merit, took leave, and returned to his father Zál at Zábulistán.
Suddenly an ardent desire arose in the heart of Káús to survey all the provinces and states of his empire. He wished to visit Túrán, and Chín, and Mikrán, and Berber, and Zirra. Having commenced his royal tour of inspection, he found the King of Berberistán in a state of rebellion, with his army prepared to dispute his authority. A severe battle was the consequence; but the refractory sovereign was soon compelled to retire, and the elders of the city came forward to sue for mercy and protection. After this triumph, Káús turned towards the mountain Káf, and visited various other countries, and in his progress became the guest of the son of Zál in Zábulistán where he stayed a month, enjoying the pleasures of the festive board and the sports of the field.
The disaffection of the King of Hámáverán, in league with the King of Misser and Shám, and the still hostile King of Berberistán, soon, however, drew him from Ním-rúz, and quitting the principality of Rustem, his arms were promptly directed against his new enemy, who in the contest which ensued, made an obstinate resistance, but was at length overpowered, and obliged to ask for quarter. After the battle, Káús was informed that the Sháh had a daughter of great beauty, named Súdáveh, possessing a form as graceful as the tall cypress, musky ringlets, and all the charms of Heaven. From the description of this damsel he became enamoured, and through the medium of a messenger, immediately offered himself to be her husband. The father did not seem to be glad at this proposal, observing to the messenger, that he had but two things in life valuable to him, and those were his daughter and his property; one was his solace and delight, and the other his support; to be deprived of both would be death to him; still he could not gainsay the wishes of a king of such power, and his conqueror. He then sorrowfully communicated the overture to his child, who, however, readily consented; and in the course of a week, the bride was sent escorted by soldiers, and accompanied by a magnificent cavalcade, consisting of a thousand horses and mules, a thousand camels, and numerous female attendants. When Súdáveh descended from her litter, glowing with beauty, with her rich dark tresses flowing to her feet, and cheeks like the rose, Káús regarded her with admiration and rapture; and so impatient was he to possess that lovely treasure, that the marriage rites were performed according to the laws of the country without delay.
The Sháh of Hámáverán, however, was not satisfied, and he continually plotted within himself how he might contrive to regain possession of Súdáveh, as well as be revenged upon the king. With this view he invited Káús to be his guest for a while; but Súdáveh cautioned the king not to trust to the treachery which dictated the invitation, as she apprehended from it nothing but mischief and disaster. The warning, however, was of no avail, for Káús accepted the proffered hospitality of his new father-in-law. He accordingly proceeded with his bride and his most famous warriors to the city, where he was received and entertained in the most sumptuous manner, seated on a gorgeous throne, and felt infinitely exhilarated with the magnificence and the hilarity by which he was surrounded. Seven days were passed in this glorious banqueting and delight; but on the succeeding night, the sound of trumpets and the war-cry was heard. The intrusion of soldiers changed the face of the scene; and the king, who had just been waited on, and pampered with such respect and devotion, was suddenly seized, together with his principal warriors, and carried off to a remote fortress, situated on a high mountain, where they were imprisoned, and guarded by a thousand valiant men. His tents were plundered, and all his treasure taken away. At this event his wife was inconsolable and deaf to all entreaties from her father, declaring that she preferred death to separation from her husband; upon which she was conveyed to the same dungeon, to mingle groans with the captive king.
