Koevasi is a female creator spirit-being of the south-east Solomon Islands, recorded most fully by C.E. Fox among the Arosi of San Cristoval and belonging to the same class of never-were-men beings that R.H. Codrington called vigona in Nggela (Florida) and figona in the islands to the south. She is imagined as a serpent-woman who existed before ordinary humankind, shaped the first people, and gave them their several languages, foods, and customs. Because she renews herself by sloughing her skin like a snake she does not die, and myth traces the coming of human mortality to a moment when this power was withheld from her descendants. Sources differ on how sharply she is to be distinguished from the winged serpent-mothers of Makira and Isabel, with whom later comparativists have sometimes identified her.
