There were two orders of temple priests, known as kahuna (experts), or kahuna pule (experts in praying). These were the priests of Ku, the war god, and the priests of Lono, the rain god who was lord of agriculture and of peace.
Each order or ‘school’ of priests had its distinctive genealogy, the mo‘o-Ku and the mo‘o-Lono. These were priests in charge of temple worship. As a caste, the priests of both gods were the mo‘o-kahuna.
Malo describes the two orders of the priesthood as follows: ‘There were two rituals which the king in his eminent station used in the worship of the gods; one was the ritual of Ku, the other that of Lono.’
‘The Ku ritual was very strict (oolea), the service most arduous (ikaika). The priests of this rite were distinct from others and outranked them.’
‘They were called priests of the order of Ku, because Ku was the highest god whom the king worshipped in following their ritual. They were also called priests of the order of Kanalu, because that was the name of their first priestly ancestor. These two names were their titles of highest distinction.’
‘The Lono ritual was milder, the service more comfortable. Its priests were, however, of a separate order and of an inferior grade. They were said to be of the order of Lono (mo‘o-Lono), because Lono was the chief object of the king’s worship when he followed the ritual. The priests of this ritual were also said to be of the order of Paliku.’ (Malo)
The priesthood of Lono traced its origin to Paliku, the great erect cliff (pali-ku) of the massive promontory named Kane-hoa-lani at the midpoint of the windward coast of Oahu.
The birthplace of Kamapua‘a was on the uplands above Ka-lua-nui Valley, a few miles southeast of Kane-hoa-lani. (Handy and Handy)
Palikū is recognized as the place of the first heiau (traditional Hawaiian religious temple) during the time of Haumea and Wākea and associated with an ancient cultural context that later underwent significant evolution.
When a great tidal wave swept Haumea, Wākea, and all of their followers out to sea, Wākea was instructed, presumably by the god Lono, ‘to cup his hands together to represent a heiau, then he caught a humuhumu-nukunukuapua‘a fish [triggerfish with a pig-like snout] . . . and stuck it head first into the cupped hands to represent a pig’. (Handy and Handy).
The followers repeated Wākea’s actions, and then the sea washed all of them ashore.
In gratitude to Lono, a temple was constructed at Palikū, and an order of priests called Mo‘o-kuauhau-o-Lono (literally “genealogical line of Lono”) was responsible for religious proceedings at this temple. (Malo)
Handy and Handy reported that the priestly order known as Palikū formerly performed rituals at temples called māpele.
Malo explains that any heiau erected by an ali‘i nui who followed the ritual of Lono was termed a mapele. The timber used in constructing the house of worship, the storied tower (lana-nu‘u-mamao) and the enclosure, would be lama wood, a native ebony (lama was selected because the word suggests enlightenment), and ti leaf served as thatching.
Māpele is defined as ‘thatched heiau. (temple) for the worship of Lono and the increase of food’ (Lono was god of abundance as well as of rain and storm). (Handy and Handy)
“The mapele was a thatched heiau in which to ask the gods blessing on the crops. Human sacrifices were not made at this heiau; pigs only were used as offerings.”
“The timber … used in the construction of the house, the fence about the grounds, and that used in constructing the lananuu-mamao was lama, and it was thatched with the leaves of the ti plant. There were also idols.”
“Any chief in rank below the king was at liberty to construct a mapele heiau, an unu o Lono, a kukoae, or an aka, but not a luakini. The right to build a luakini belonged to the king alone. The mapele, however, was the kind of heiau in which the chiefs and the king himself prayed most frequently.”
“The luakini was a war temple, heiau-wai-kaua, which the king, in his capacity as ruler over all, built when he was about to make war upon another independent monarch, or when he heard that some other king was about to make war against him; also when he wished to make the crops flourish he might build a luakini.”
“Luakini (was a) heiau of the highest class, a war-temple, in which human sacrifices were offered; named from a pit, lua, and kini, many; into which the mouldering remains were finally cast.” (Malo)
“When the people and the priests saw that the services of the luakini were well conducted, then they began to have confidence in the stability of the government, and they put up other places of worship, such as the Mapele, the Kukoea, the Hale-o-Lono.”
“These heiaus were of the kind known as hoouluulu (hoouluulu ai = to make food grow), and were to bring rain from heaven and make the crops abundant, bringing wealth to the people, blessing to the government, prosperity to the land.” (Malo)
