R9.1.2. Sun and Moon captured by creditor, thus causing eclipse
This story was collected from the Didayi people in Orissa, India.
After the wedding, Rumrok had a quarrel with the Sun, and went to live separately. Some time later, the merchant showed up, asking for the return of the bamboo pin, but Rumrok sent him to the Sun, since he was now the head of the house. The Sun returned the pin, but the merchant did not accept it - saying that with interest, the Sun now owed him one lakh (one hundred thousand) pins. The Sun could not pay, so he sent the merchant away.
Years passed by, and the merchant kept showing up; the Sun kept hiding from his creditor. One day the merchant threatened him, saying he would take his wife the Moon as payment. So ever since then, whenever the merchant shows up to collect their debt, the Sun and the Moon hide in their house, only leaving a crack in the door so they can peek out and see when the debtor is gone...
