They believed in one supreme God, Athua-rahai, creator and governor of the world, and of all other gods. They gave him a consort, who however was not of the same nature, but of a material and very firm substance, and therefore called O-te-Papa, that is to say, Rock. From this pair proceeded a goddess of the moon, the gods of the stars, the winds, and the sea, and the protecting deities of the several islands. After the chief god had created the sun, he conveyed his consort, the mighty Rock, from the West to the East over the sea: in their progress, some portions of her substance separated from her, and formed the islands.
Besides the gods of the second rank, they believed also in inferior deities, and in a wicked genius, who killed men suddenly at the requisition of the priests—an article of faith which this order doubtless found very convenient. They also supposed that a genius dwelt in every man, thinking and feeling in him, and separated himself from the body after death, but without removing from it; often inhabiting the wooden images which are erected in the burial-places, but sometimes stealing at night into their habitations, and killing the sleepers, whose hearts and entrails he devoured. This belief in ghosts is perhaps not more universal in Tahaiti than among civilized nations.
According to another of Cook's companions, the supreme God united departed souls with his own existence, which was signified by the phrase, "He eats them." This was purification, after which the soul, or the genius, reached the abode of eternal happiness. If a man, for some months before his death, had kept himself apart from women, he did not require this purification, but went direct to Heaven. The pride of the Yeris prompted them to believe in a Heaven peculiar to themselves, where they should associate only with their equals in birth.
The Tahaitians of rank had each a Marai sacred to themselves, and which served for their religious assemblies. The greatest and most solemn of these meetings were held at the Marai of the Kings. Here the priests harangued the people; and here was performed the rite which stained the otherwise amiable character of these islanders—the offering of human sacrifices! Cook was once present at one of these detestable oblations, and describes it circumstantially. Its object was to propitiate the assistance of the Gods, in a war about to be undertaken.
The victim was always of the lower class. He was first killed, and the ceremonies were afterwards performed by the priests, and many prayers recited, in presence of the King and people. One of the formalities was the presentation of the left eye to the King, which however he did not receive. From this, Cook infers that the Tahaitians had at some period been eaters of human flesh, and that this morsel was offered to the King as a delicacy. If this conjecture be well-founded, which I think it is not, so horrible an appetite must have long since disappeared, as not a trace of it now remains. It is besides altogether contrary to the character and manners of the people. So, indeed, is the oblation of human victims; but this horrible rite had certainly been introduced by the priests, for the purpose of attracting towards their office an increased degree of veneration and awe. The burial of the dead was accompanied by many religious ceremonies, but with the birth of a child, or the celebration of marriage, their religion was no way concerned.
If a woman bore her lover a child, which he acknowledged to be his, the marriage was concluded without further ceremony, but was easily dissolved and a new connexion formed.
A married man would sometimes entertain a concubine, but never had more than one wife. The kings only formed an exception to this rule. The last monarch married at the same time the four daughters of a neighbouring king, and during our visit they were all living and respected as his widows. One only of them had brought him children; and when during the latter years of his government he became a convert to the Christian religion, this one only passed for his lawful consort.
In both peninsulas of Tahaiti the form of government was monarchical, and each had its own king, assisted by a council of Yeris, whom he consulted on all important occasions. These were held in great veneration among the people. No one, not even a female or a Yeri of the highest rank, might appear before them without uncovering the upper part of the body—a token of respect which was usually paid only to the Gods in prayer or in passing a Marai. Before the princesses, the female sex only uncovered themselves. All his subjects were much attached to the sovereign, who reigned under a most singular law of succession.
As soon as a son was born to him, the sovereignty passed from the king to the infant, in whose name, and during whose minority only, the father continued to exercise the Regency.
