One of the best sources, if not the best source, of information on these topics is Mariner's _Tonga Islands_, which tells us of the condition of Cook's "Friendly Islanders" eighty years ago, before { 162} European influence was sensibly felt among them. Mariner, a youth of fair education and of no inconsiderable natural ability (as the work which was drawn up from the materials he furnished shows), was about fifteen years of age when his ship was attacked and plundered by the Tongans: he remained four years in the islands, familiarised himself with the language, lived the life of the people, became intimate with many of them, and had every opportunity of acquainting himself with their opinions, as well as with their habits and customs. He seems to have been devoid of prejudices, theological or other, and the impression of strict accuracy which his statements convey has been justified by all the knowledge of Polynesian life which has been subsequently acquired.
It is desirable, therefore, to pay close attention to that which Mariner tells us about the theological views of these people:--
The human soul,[42] after its separation from the body, is termed a _hotooa_ (a god or spirit), and is believed to exist in the shape of the body; to have the same propensities as during life, but to be corrected by a more enlightened understanding, by which it readily distinguishes good from evil, truth from falsehood, right from wrong; having the same attributes as the original gods, but in a minor degree, and having its dwelling for ever in the happy regions of Bolotoo, holding the same rank in regard to other souls as during this life; it has, however, the power of returning to Tonga to inspire priests, relations, or others, or to appear in dreams to those it wishes to admonish; { 163} and sometimes to the external eye in the form of a ghost or apparition; but this power of reappearance at Tonga particularly belongs to the souls of chiefs rather than of matabooles (vol. ii. p. 130).
The word "hotooa" is the same as that which is usually spelt "atua" by Polynesian philologues, and it will be convenient to adopt this spelling. Now under this head of "_Atuas_ or supernatural intelligent beings" the Tongans include:--
