Origin Ancient in West Africa and continuous in its diaspora

The cowrie shell is at once currency, ornament and, in Yoruba religion and its diaspora, a divining and consecrating instrument. In divination a set of sixteen cowries is cast and read by the way each falls, mouth up or mouth down, in the oracle called diloggun or merindilogun; cowries also adorn the beaded and consecrated objects of the orisha, cover divining boards and mark the regalia of priesthood. The shell's natural slit, suggesting a mouth or an eye, underlies its use as a thing that can speak or see on the orisha's behalf.

The Shell That Is Money, Ornament and Oracle

The cowrie shell is at once currency, ornament and, in Yoruba religion and its diaspora, a divining and consecrating instrument, and it is this last use that gives it its sacred standing.

Divining with shells

In one widespread form of Yoruba divination a set of cowrie shells is cast, and the pattern of shells falling mouth up or mouth down is read according to a fixed system to deliver the response of the deities, so the shells become the medium through which the divine word is obtained, a more accessible counterpart to the more complex divination of the Ifa priesthood. The shells are also used to consecrate and adorn the sacred objects and the emblems of the orishas, and they figure in the regalia of the deities and their priests, so the cowrie is woven through the material life of the religion.

From money to the sacred

The cowrie was a real currency across wide regions of Africa and beyond, and its value and its associations with wealth carried over into its religious use, so that the shell that served as money became also an ornament of the gods and an instrument of their speech. Carried across the Atlantic with the Yoruba traditions, the cowrie kept its divinatory and consecrating roles in the religions of the diaspora, in Cuba and Brazil and beyond, where shell divination and the adornment of sacred objects with cowries continued. The single small shell thus gathers together the economic, the decorative and the sacred, and in the hands of a diviner it becomes the means by which the deities are asked and answer.

Cut Flat on One Side So It Can Fall Two Ways

The shells used in divination are the natural shell of Cypraea moneta, historically gathered and traded in bulk along West African trade routes where they also circulated as actual currency for a period, a genuine dual history as both money and oracle rather than a purely symbolic object from the outset.

Preparation for divination

A shell intended for divination is filed or cut flat on its back, so that when cast it can land showing either its natural ridged, convex face or the flattened cut face, giving the system its basic binary reading unit, and a set of sixteen shells is commonly used in the Yoruba divination system called merindinlogun, a related but distinct method from the palm nut and chain based Ifa system.

Who casts them, and the ordinary use that carries no restriction

Casting shells for actual divination is restricted to trained, initiated diviners, often though not exclusively priestesses of specific orishas within particular lineages, a genuine skill and initiation based restriction rather than something any interested person may take up. A diviner's working set is a personal professional tool, cared for and given offerings much like other consecrated ritual objects, and is not lent or shared casually, a restriction that has nothing to do with cowrie shells used purely as jewelry or hair ornamentation, which carry no such limitation at all.
