In Rotinese cosmology the supreme power is a single Lord of the Heavens, addressed in ordinary speech as Lamatuak, 'the Lord,' and in fuller ritual form as Manetualain, 'the Exalted Lord on High.' He bears the title Lord of the Sun and Moon, the two luminaries standing as the visible sign of his sovereignty over the sky, and he is held to ordain the span of human life and the certainty of death. With the coming of Christianity the same name was carried over for the Christian God; sources differ on how far the pre-Christian Lord was conceived as a personal being rather than an encompassing sky-power.
