In Hawaiian mythology, Laka is the name of two different popular heroes from Polynesian mythology. (In other parts of Polynesia they are known as Rātā, Rata, Lata, Ata, or Lasa).
In one Hawaiian legend, Laka is the daughter of the Ali'i nui Wahieloa and Hoʻolaukahili, grandson of Kahaʻinuiahema. He plans to sail to Hawaii to avenge the murder of his father, but his canoe-building is thwarted by the little gods of the forest. Because of his offerings to the great gods, however, they give him two outriggers that binds together for his long voyage. He and his companions successfully steal the bones of his father from the cave of Kai-kapu.[1]
Four deities of this name can be differentiated:[2]
In the Marquesan version of the myth, Aka is a great voyager, grandson of Tafaki. He made a historic voyage to Aotona (Rarotonga) in what are now the Cook Islands to obtain the highly prized feathers of a red parrot as gifts for his son and daughter. The voyage was done in a great outrigger canoe named Va'ahiva that had 140 rowers. Of these, 100 die of hunger before they reach Aotona, where they capture enough parrots to fill 140 bags with their feathers.[6] [7]
In Samoa, where this hero's name is Lata, he is a great canoe builder originally from Fiji. He builds a huge outrigger canoe on the island of Ta'u and sails to Savai'i, where a mountain is named after him. From there, he sails to Tonga where he teaches the inhabitants better ways to build canoes.[8]
In Tonga, he is Lasa, who captures the chief of the forest elves, Haelefeke, and compels him to help him build a great canoe and pilot it to Fiji. En route, they are tested by various demons.[9]
