Long
 time ago in West Java, lived a beautiful girl named Dayang Sumbi. She 
was also smart and clever. Her beauty and intelligence made a prince 
from the heavenly kingdom of Kahyangan desire her as his wife. The 
prince asked permission from his father to marry Dayang Sumbi. People 
from Kahyangan could never live side by side with humans, but his father
 approved on one condition, when they had a child, the prince would 
transform into a dog. The prince accepted the condition.
They
 get married and lived happily in the woods until Dayang Sumbi gave 
birth to a baby boy. The prince then changed into a dog named Tumang. 
Their son is named Sangkuriang. He was very smart and handsome like his 
father. Everyday, he hunted animals and looked for fruits to eat. One 
day, when he was hunting, Sangkuriang accidentally killed Tumang. His 
arrow missed the deer he was targeting and hit Tumang instead. He went 
home and tells her mother about the dog. “What?” Dayang Sumbi was 
appalled. Driven by sadness and anger, she grabbed a weaving tool and 
hit Sangkuriang’s head with it. Dayang Sumbi was so sad; she didn’t pay 
any attention to Sangkuriang and started to cry.
Sangkuriang
 feel sad and also confused. How can his mother love a dog more than 
him? Sangkuriang then decided to go away from their home and went on a 
journey. In the morning, Dayang Sumbi finally stopped crying. She 
started to feel better, so she went to find Sangkuriang. But her son was
 no where to be found. She looked everywhere but still couldn’t find 
him. Finally, she went home with nothing. She was exhausted. She fell 
asleep, and in her dream, she meets her husband. “Dayang Sumbi, don’t be
 sad. Go look for my body in the woods and get the heart. Soak it with 
water, and use the water to bathe, and you will look young forever,” 
said the prince in her dream. After bathing with the water used to soak 
the dog’s heart, Dayang Sumbi looked more beautiful and even younger.
And
 time passed by. Sangkuriang on his journey stopped at a village and met
 and fell in love with a beautiful girl.He didn’t realize that the 
village was his homeland and the beautiful girl was his own mother, 
Dayang Sumbi. Their love grew naturally and he asked the girl to marry 
him. One day, Sangkuriang was going on a hunt. He asked Dayang Sumbi to 
fix the turban on his head. Dayang Sumbi was startled when she saw a 
scar on his head at the same place where she, years ago, hit Sangkuriang
 on the head.
After
 the young man left, Dayang Sumbi prayed for guidance. After praying, 
she became convinced that the young man was indeed her missing son. She 
realized that she had to do something to prevent Sangkuriang from 
marrying her. But she did not wish to disappoint him by cancelling the 
wedding. So, although she agreed to marry Sangkuriang, she would do so 
only on the condition that he provides her with a lake and built a 
beautiful boat, all in one night.
Sangkuriang
 accepted this condition without a doubt. He had spent his youth 
studying magical arts. After the sun went down, Sangkuriang went to the 
hill. Then he called a group of genie to build a dam around Citarum 
River. Then, he commands the genies to cut down trees and build a boat. A
 few moments before dawn, Sangkuriang and his genie servants almost 
finished the boat.
Dayang
 Sumbi, who had been spying on him, realised that Sangkuriang would 
fulfill the condition she had set. Dayang Sumbi immediately woke all the
 women in the village and asked them to wave a long red scarf. All the 
women in the village were waving red scarf, making it look as if dawn 
was breaking. Deceived by false dawn, the cock crowed and farmers rose 
for the new day.
Sangkuriang’s
 genie servants immediately dropped their work and ran for cover from 
the sun, which they feared. Sangkuriang grew furious. With all his 
anger, he kicked the unfinished boat. The boat flew and landed on a 
valley. The boat then became a mountain, called Mount Tangkuban Perahu 
(Tangkuban means upturned or upside down, and Perahu means boat). With 
his power, he destroyed the dam. The water drained from the lake 
becoming a wide plain and nowadays became a city called Bandung (from 
the word Bendung, which means Dam).
