Sāngone (Sāmoan sā = tribe, Fijian (n)gone = child), was the name of a turtle from divine origin and featuring in Tongan myths about the Tuʻi Tonga king named Tuʻitātui in the beginning of the 12th century AD. Part of the history features prominently in a famous lakalaka written by queen Sālote somewhere around 1940, when the shell, claimed to be the original one from Sāngone herself was transferred to the Tupou College museum.
The beautiful goddess Hinahengi from Pulotu came to Mokotuʻu, a tract near Longoteme on Tongatapu, to wash her hair with the clay and then to dry it. She fell asleep. Then a Sāmoan named Lekapai came along, saw her, and tied her hair to the trees around. He woke her up, but she could not get up, because her head was immovable in the bonds. Hina begged to be liberated, and Lekapai agreed when she would become his wife. So happened and they lived together for a long long time.
One day a great storm destroyed the plantation of Lekapai in Sāmoa. Lekapai swore revenge on the god of the winds and set out in his canoe. He arrived at an island, but there was no opening in the reef. The boat was turned over, but Lekapai made it alive to the shore. He went inland and came at a house where a beautiful girl was standing. She turned out to be the daughter of the wind god, who was sleeping at that momernt. When the god slept it was calm, when he awoke there were storms. The girl told Lekapai to tiptoe to her sleeping father, to take a lock of his hear and to tie it to a big tree, then another lock to another tree, and so on. Next the god was woken up and found himself powerless. Soon he and Lekapai came to an agreement. He would live here and marry the damsel, and the god himself would retire to some other premises in the bush. So Lekapai and the girl lived together for a long long time.
Lekapai got desire to visit his family in Sāmoa. His wife acquiesced and said that he could travel on the back of her mother, who happened to be a turtle with the name Sāngone. She gave him instruction what to do and not to do.
