There was once a king, who had lost his wife. They had a family of thirteen—twelve gallant sons, and one daughter, who was exquisitely beautiful.
For twelve years after his wife's death the king grieved very much; he used to go daily to her tomb, and there weep, and pray, and give away alms to the poor. He thought never to marry again; for he had promised his dying wife never to give her children a stepmother.
One day, when visiting his dead wife's grave as usual, he saw beside him a maiden so entrancingly fair, that he fell in love with her, and soon made her his second queen. But before long he found out that he had made a great mistake. Though she was so beautiful she turned out to be a wicked sorceress, and not only made the king himself unhappy, but proved most unkind to his children, whom she wished out of the way, so that her own little son might inherit the kingdom.
One day, when the king was far away, at war against his enemies, the queen went into her stepchildren's apartments, and pronounced some magical words—on which every one of the twelve princes flew away in the shape of an eagle, and the princess was changed into a dove.
The queen looked out of the window, to see in what direction they would fly, when she saw right under the window an old man, with a beard as white as snow.
"What are you here for, old man?" she asked.
"To be witness of your deed," he answered.
"Then you saw it?"
"I saw it."
"Then be what I command!"
She whispered some magical words. The old man disappeared in a blaze of sunshine; and the queen, as she stood there, dumb with terror, was changed into a basilisk.
The basilisk ran off in fright; trying to hide herself underground. But her glance was so deadly, that it killed every one she looked at; so that all the people in the palace were soon dead, including her own son, whom she slew by merely looking at him. And this once populous and happy royal residence quickly became an uninhabited ruin, which no one dared approach, for fear of the basilisk lurking in its underground vaults.
