The Legend of Lake Toba

The Legend of Lake Toba - Once, a fisherman named Batara Guru Sahala live in Batakland. One day, he caught a fish. He was surprised to find that the fish could talk. It begged Sahala to set it free. He did accordingly.

As soon as the fish was free, it changed into a woman. She was so beautiful that Sahala fell in love with her at once. He asked her to marry him. The woman agreed to marry Sahala. However, she told him that he must never let out the secret that she was once a fish. Sahala promised her that he would not tell anyone about it.

They were happily married, and had two daughters. Every morning Sahala went out fishing. His daughters would bring him his lunch. One day, however, instead of bringing the food to their father, the two girls ate it.

When Sahala knew what they had done with the meal, he got very angry. He shouted at them saying, ''You behaved exactly like the daughters of a fish...!''

The girls did not know what their father meant. They went home and asked their mother about it. Their mother was very annoyed. Although Sahala apologized to her later, she would not forgive him for breaking his promise.

Then the earth began to shake, and volcanoes started to erupt. The earth cracked and formed a big hole. People said that hole became Lake Toba.
