The Moon is the Sun's counterpart in Angan cosmology, joined to it in the sun-and-moon myth as spouse, sibling, or twin emanation depending on the telling. The Moon is closely tied to women, to menstruation and to the reckoning of months, its waxing and waning read as a bodily cycle. Among the Baruya, as described by Maurice Godelier, and the Ankave, described by Pascale Bonnemere, the lunar body figures in accounts of the origin of female bleeding and of the separation of the sexes.
