Paupiyahe was the eldest and Tantanu was the youngest. Paupiyahe was a lazy guy but Tantanu was a hard-working man.

The Solomon Islanders freely crossed the narrow channel to the Kangu area of Buin to visit the two brothers. 

Lazy Paupiyahe’s visitors usually went home hungry because he had nothing to eat. On the other hand, Tantanu’s visitors went home with loads of surplus food.

Paupiyahe’s visitors didn’t bother returning but instead headed Tantanu’s way. This made Paupiyahe jealous and hated his younger brother‘s popularity.

So Paupiyahe decided to chase Tantanu away from Buin. It was on a beautiful morning when the sun was rising with sparkling rays that Tantanu departed from Tonolei Harbour.

Paupiyahe stood on top of the mountain and ordered him away from Buin. The hardworking Tantanu set off towards Siwai along the coastline.  Paupiyahe shouted at him to continue going until he was out of sight.

Tantanu went on until he reached Moila Point, where he was hidden from the lazy and aggressive Paupiyahe.

So Tantanu was in a new land and, to keep himself company walking along the Mamagota coastline, he played music on his bamboo flute. He ventured inland a little and came to a small hamlet called Siuwai.

When he arrived there, he was surprised to find only small kids. There was no elderly person. The kids looked hungry so Tantanu asked them of what food they were eating. The kids told him they eat things that hung on trees which their parents collected in the big forest.

With sympathy, Tantanu told the poor kids to boil some water in a big clay pot. The kids fetched water from the river and Tantanu got in the pot that he instructed the kids to make a fire and boil him.

The hungry children sat around the pot keeping the fire going and awaited the results.

To their surprise, they saw a man coming from the river where they washed. The person was Tantanu, who they thought was boiling in the clay pot. Tantanu told them to look in the pot and see what was there.

When they looked, they saw the clay pot they was full of all sorts of food.  The surprised kids started shouting and giving names to the food items like kaukau (potatoes), peero (bananas), hame (taro) and poro (yam).

The kids were grateful and thanked Tantanu for providing them with all kinds of food they had never tasted before. They ate enough food and went into the bush to tell their parents.

On their way, they were shouting and singing traditional songs describing the food they ate. The song they sang was Kapukeng Maamiyoko Tantanu which means, the Tantanu God has given us different types of food.

From tahe distance, the parents heard the song and left the food gathering and went to meet their kids. The children joyfully announced to their parents that Tantanu had given them food.

They returned home together, happily singing and shouting at the top of their voices.

Tantanu also provided banana suckers and other food plants for planting.

Generation after generation have passed on their skills and knowledge and the area where this myth originated is still kept as a sacred place and a sanctuary and it is where the name Siuwai comes from.
