Ledo, the sun, and Bula, the moon, form the fixed celestial dyad of Rotinese ritual language, named in parallel as Ledo Holo and Bula Kai. The sun governs daylight and the dry season and, with the moon, orders the reckoning of ritual time. In Rotinese thought the luminaries are the manifest face of the Lord of the Sun and Moon rather than independent objects of cult.
