On the land of Parahyangan, there lived a beautiful princess named Dayang Sumbi. Because of her oath, she had to marry a dog named Tumang. Dayang Sumbi and her dog lived happily and blessed with a boy, Sangkuriang. The boy didnt know that the dog was his father.
One day, Dayang Sumbi asked Sangkuriang with his dog to hunt a deer. Sangkuriang got nothing. He did not want to disappoint his mother. He decided to kill the dog. Dayang Sumbi thought it was venison. After knowing the truth, Sangkuriang was hit and expelled by his mother.
Sangkuriang grew overseas into a handsome and powerful man. Then, he met Dayang Sumbi and fell in love with her. The day before the wedding, Dayang Sumbi realized that Sangkuriang was her son. Dayang Sumbi wanted to thwart the marriage. She gave a condition to make a dam that covered the entire hill and a boat during one night.
Sangkuriang agreed and worked with the help of many genies. The dam and boat were almost finished. Dayang Sumbi prayed to God. The roosters crowed and all genies left that job. Sangkuriang realized that he had been tricked. He was angry and kicked the boat into the middle of the forest. Then, the boat shaped like a mountain. That is the legend of Tangkuban Parahu.
