There is a kingdom in Priangan Land. Live a happy family, a father in form of dog (his name is Tumang), a mother (her name is Dayang Sumbi), and a child call Sangkuriang. Tumang is demigod possessing magic powers.
One day, Dayang Sumbi asked her son to go hunting in the nearest jungle and she wanted some deer liver or venison. So Sangkuriang went hunting with his lovely dog, Tumang, to please his mother. After hunting all day with empty-handed, Sangkuriang began desperate and worried. Think shortly, Sangkuriang took his arrow and shot his dog. Then he took the dog liver or flesh and carried home.
He gave dog liver or flesh to his mother. Soon Dayang Sumbi fine out that Sangkuriang lied to her. She knew Sangkuriang had killed Tumang. So, She angry and hit Sangkuriang head. Sangkuriang got wounded and scar. Sangkuriang cast away from their home.
Years go bye, Sangkuriang had travel many places and on one day, he arrived at a village which is used to be his home. He met a beautiful woman whom actually his mother and felt in love with her.
Their love grew naturally and one day, when they were discussing their wedding plans, Dayang Sumbi suddenly realised that the profile of Sangkuriang’s head matched that of her only son’s who had left twenty years earlier. How could she marry her own son? But she did not wish to dissapointed him by canceling the wedding. So, although she agreed to marry Sangkuriang, she would do so only on the condition that he provide her with a lake and a boat with which they could sail on the dawn of their wedding day.
Sangkuriang accepted this condition and built a lake by damming the Citarum river. With a dawn just moment away and the boat almost complete, Dayang Sumbi realised that Sangkuriang would fulfill the condition she had set. With a wave of her supernatural shawl, she lit up the eastern horizon with flashes of light. Deceived by false dawn, the cock crowed and farmers rose for the new day.
With his work not yet complete, SangkuriaNg realised that his endeavor were lost. With all his anger, he kicked the boat that he himself had built. The boat fell over and, in so doing become the mountain TANGKUBAN PARAHU (in Sundanese, TANGKUBAN means upturned or upside down, and PARAHU means boat). With the dam torn asunder, the water drained from the lake becoming a wide plain and nowadays became a city called BANDUNG (from the word BENDUNG, which means Dam).
