Once upon a time, In ancient times, the story of a princess in West Java named Dayang Sumbi. He has a son named Sangkuriang. The boy is very fond of hunting.

He hunts accompanied by Tumang, the pet's favorite dog. Sangkuriang did not know that the dog was a god and her father.

On one day Tumang refused to follow his orders to pursue game. So the dog was thrown into the forest.

When returning to the palace, Sangkuriang told the incident to his mother. Dayang Sumbi is not furious when he heard the story. He accidentally hit Sangkuriang's head with a spoon of rice he held. Sangkuriang was injured. He was very disappointed and went wandering.

After that incident, Dayang Sumbi deeply regretted her. He always prayed and was very diligent ascetic. Once upon a time, the gods gave him a gift. He will be forever young and has eternal beauty.

After years of wandering, Sangkuriang finally intends to return to his homeland. Once there, the kingdom has changed completely. There he encountered a beautiful girl, who is none other than Dayang Sumbi. Fascinated by the beauty of the woman then, Sangkuriang proposed to her. Because the young man was very handsome, Dayang Sumbi was very fascinated by him.

One day Sangkuriang asked to say goodbye to hunt. She asks Dayang Sumbi for the tidying of her headband. What a surprise Dayang Sumbi to see the scar on the head of her future husband. The wound was exactly like the wound of his son who had gone abroad. After a long time he noticed, the young man's face was very similar to his son's face. He became very frightened.

So then he sought the effort to thwart the process of the proposal. He proposed two conditions. First, he asked the young man to stem the Citarum river. And second, he asked Sangkuriang to make a big boat to cross the river. Both conditions must be met before dawn.

That night Sangkuriang did tapa. With his magic he mobilized supernatural beings to help complete the work. Dayang Sumbi also secretly peek at the work. As soon as the work is nearing completion, Dayang Sumbi commands his troops to roll out red silk fabrics east of the city.

When witnessing the color of red in the east of the city, Sangkuriang thought it was early morning. He stopped his work. He is very angry because it means he can not meet the requirements that Dayang Sumbi requested.

With his strength he breaks down the dam he makes. A great flood swept through the city. He then kicked the big boat he made. The canoe floated and fell into a mountain called "Tangkuban Perahu."
