The Tsar said in answer: "My friends, ye tell me the truth." Then he turned to Simeon the thief and asked: "Well, Simeon, canst thou go to the thrice-ninth land, to the thirtieth kingdom, and steal for me Yelena the Beautiful? I am strongly in love with her, and if thou canst steal her for me I 'll give thee a great reward".
"Stealing is my art, your Majesty," anwcrcd the seventh Simeon, "and I will steal her for you; only give the command".
"Not only do I give the command, but I beg; thee to do it; and delay no longer at my court, but take for thyself troops and money, whatever is needed".
"Neither troops nor treasure do I need," answered he. "Let all of us brothers go together, and I will get Tsarevna Yelena the Beautiful".
The Tsar did not like to part with all the Simeons; still, though he regretted it, he was obliged to let them all go together. Meanwhile the forge was built in the court, and the eldest Simeon forged an iron pillar to the very sky; the second Simeon climbed on that pillar to the top, and looked in the direction in which was the kingdom of the father of Yelena the Beautiful. After he had looked he cried from the top of the pillar: "Your Majesty, I see Yelena the Beautiful sitting beyond the thrice-ninth land in the thirtieth kingdom under a window; her marrow flows from bone to bone".
Now the Tsar was still more enticed by her beauty, and said to the Simeons in a loud voice: "My friends, start on your journey at once, for I cannot live without Yelena, the beautiful Tsarevna".
The eldest Simeon made an axe for the third, and for the fifth he made a gun; and after that they took bread for the journey, and Simeon the Thief took a cat, and they went their way. Simeon the Thief had made the cat so used to him that she ran after him everywhere like a dog; and if he stopped on the road, or in any other place, the cat stood on her hind legs, rubbed against him, and purred. So the brothers went their way for some time, and at last came to the sea, which they had to cross, and there was nothing to cross upon. They walked along the shore and looked for a tree of some kind to make a vessel, and they found a very large oak. The third Simeon took his axe and cut the oak at the very root, and then with one stroke and another he made straightway a ship, which was rigged, and in the ship were various costly goods. All the Simeons sat on that ship and sailed on their journey.
In a few months they arrived safely at the place where it was necessary for them to go. When they entered the harbor they cast anchor at once. On the following day Simeon the Thief took his cat and went into the town, and coming to the Tsar's palace he stood opposite the window of Yelena the Beautiful. At that moment the cat stood on her hind legs and began to rub against him and to purr. It is necessary to say that in that kingdom they knew nothing of cats, and had not heard what kind of beast the cat is.
Tsarevna Yelena the Beautiful was sitting at the window; and seeing the cat, sent straightway her nurses and maidens to ask Simeon what kind of beast that was, would he not sell it, and what price would he take. The maidens and nurses ran out in the street and asked Simeon what kind of beast that was, and would he not sell it?
Simeon answered: "My ladies, be pleased to relate to her Highness, Yelena the Beautiful, that this little beast is called a cat, that I will not sell it, but if she wishes to have it I will give it to her without price".
The maidens and nurses ran straight to the palace and told what they had heard from Simeon.
Tsarcvna Yelena the Beautiful was rejoiced beyond measure, ran out herself, and asked Simeon would he not sell the cat.
Simeon said: "Your Highness, I will not sell the cat; but if you like her, then I make you a present of her".
The Tsarevna took the cat in her arms and went to the palace, and Simeon she commanded to follow. When she came to the palace the Tsarevna went to her father, and showed him the cat, explaining that a certain foreigner had given it to her as a present.
The Tsar, seeing such a wonderful little beast, was greatly delighted, and gave orders to call Simeon the Thief; and when he came, the Tsar wished to reward him with money for the cat; but as Simeon would not take it, he said: "My friend, live for the time in my house, and meanwhile, in your presence, the cat will become better used to my daughter".
To this Simeon did not agree, and said to the Tsar: "Your Majesty, I could live with great delight in your house if I had not the ship on which I came to your kingdom, and which I cannot commit to any one; but if you command, me I will come every day and teach the cat to know your daughter".
The Tsar commanded Simeon to come every day. Simeon began to visit Tsarevna Yelena the Beautiful. One day he said to her: "Gracious lady, often have I come here; I see that you are not pleased to walk anywhere; you might come to my ship, and I would show you such costly brocades as you have never seen till this day".
The Tsarevna went straightway to her father and began to beg permission to go to the ship-wharf. The Tsar permitted her, and told her to take nurses and maidens, and go with Simeon.
As soon as they came to the wharf Simeon invited her to his ship, and when she entered the ship Simeon and his brothers began to show the Tsarevna various rich brocades. Then Simeon the Thief said to Yelena the Beautiful: "Now be pleased to tell your nurses and maidens to leave the ship, because I wish to show you things so costly that they should not see them".
The Tsarevna commanded her maidens and nurses to leave the ship. As soon as they had gone, Simeon the Thief ordered his brothers in silence to cut off the anchor and go to sea with all sail; meanwhile he showed the Tsarevna rich goods and made her presents of some. About two hours had passed while he was showing the stuffs. At last she said it was time for her to go home, the Tsar her father would expect her to dinner. Then she went out of the cabin and saw that the ship was under sail and land no longer in sight.
She struck herself on the breast, turned into a swan, and flew off. The fifth Simeon took his gun that minute and wounded the swan; the sixth Simeon did not let her fall to the water, but brought her back to the ship, where she became a maiden as before.
The nurses and maidens who were at the wharf, seeing the ship move away from the shore with the Tsarevna, ran straight to the Tsar and told him of Simeon's deceit. Then the Tsar sent a whole fleet in pursuit. When this fleet coming up was very near the ship of the Simeons, the fourth Simeon seized the prow and conducted the ship to the underground kingdom. When the ship had become entirely invisible, the commanders of the fleet thought it was lost, with the Tsarevna; therefore they returned, and reported to the Tsar that Simeon's ship had gone to the bottom with Yelena the Beautiful.
The Simeons arrived at their own kingdom successfully, delivered Yelena the Beautiful to Tsar Ador, who for such a mighty service of the Simeons gave liberty to them all, and plenty of gold, silver, and precious stones, married Yelena the Beautiful himself, and lived with her many years.
