His sister was surprised to see him, and frightened, and she said: "We must be very careful and cunning, lest the dragon should find us out, for it is impossible to escape from this place, nor can we save ourselves from the dragon. His rooms are all full of princesses whom he has taken captive, and who cannot climb down the mountain."
And she asked her brother how he had been able to climb it. He told her about the snake, and then he said—
"This evening, when the dragon comes back to his house, ask him where his strength lies, and I will come to-morrow and you shall tell me."
In the evening the dragon came home, and the Princess asked him where his strength lay, and the dragon told her that he had three golden hairs on the top of his head, and with these hairs one could open a room in which there were three doves; and were any one to kill the first dove, he would grow sick; and were any one to kill the second dove, he would grow worse; and if any one were to kill the third dove, he would die.
The next day, when the dragon had gone out on his daily business, which was to look for disobedient children in the country round and to catch them, the Princess went to her brother and told him what the dragon had said.
Orestes told her that when the dragon came back in the evening and fell asleep, she was to take a pair of scissors and cut off the three golden hairs, and open the secret room and kill the doves which were in it.
In the evening when the dragon came back and fell asleep, which he did at once, for he was tired, the Princess took a pair of scissors, cut off his three golden hairs, opened the secret room and killed the doves; and immediately the dragon gave a great groan and died.
As soon as he was dead, all the doors of all the rooms in the house, which had been carefully locked, flew open, and hundreds and hundreds of prisoners were set free. Among these there were three princesses. Orestes and his sister walked with these three princesses to the edge of the mountain top, and when they reached it Orestes saw his brothers, who were waiting at the foot of the hill.
Orestes took a rope, and first he let down his sister; then he let down the eldest of the princesses and said: "She shall be the wife of my eldest brother." Afterwards he let down the second of the princesses, and said: "She shall be the wife of my second brother." And, lastly, he let down the youngest princess, and he said: "This shall be my wife."
But when his brothers saw that the youngest princess was the most beautiful of the three, they were angry, and they jerked the rope out of Orestes' hands and left him on the top of the mountain.
