And I saw when the Lamb opened one of the seals, and I heard, as it were the noise of thunder, one of the four beasts saying, ''Come and see '' . . . . And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood; And the stars of heaven fell unto the earth. . . . And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places.-Rev. 6:1, 12-14Abstract.Christian notions of the Apocalypse, which were first introduced to Huli speakers of the Southern Highlands of Papua New Guinea during the 1950s, encountered an existing indigenous eschatology, or doctrine of last things. Precontact Huli cosmology posited a moral constitution for the fertility of the universe in which the health of people and the land reflected the state of moral order in Huli society. Failure in social behaviour, which could be gauged from the declining condition of the ''skin'' of the land, was attributed to an inexorable process of loss of the knowledge of customary lore. Human agency, however, was accorded a significant role in redressing this universal tendency to entropy, and ritual leaders claimed the ability to induce an apocalyptic, earth-renewing fall of fertile soil from the sky. The adoption of Christian understandings of the Apocalypse as the revelation of divine will, and the abandonment of most of the precontact rituals, have thus had significant consequences for Huli conceptions of the role of human agency in history, and for the nature of their engagement with the land.In a series of letters set out in the Book of Revelation, Saint John the Divine announces his apocalyptic vision to the seven churches of Asia.
