Chapter I
What it means
Cowries mean wealth and blessing. Because they were money, a shrine or garment covered in cowries showed abundance offered to the gods. They are sewn on to the beaded objects, crowns and costumes of the orisa, and given as offerings.
They are also voices. In merindinlogun divination, sixteen shells are thrown on a mat, and the number that land with the opening upward points to a sign, which the diviner interprets with stories and advice from the orisa.
Chapter II
Where it comes from
Cowries from the Indian Ocean circulated as money in West Africa for centuries, and in the 18th and 19th centuries European traders shipped them in enormous numbers. Their value collapsed under colonial currencies, but their religious meaning remained.
Cowrie divination crossed the Atlantic with enslaved Yoruba people and survives as dilogún in Cuban Santería and as jogo de búzios in Brazilian Candomblé.
Chapter III
Where you see it today
Cowries are cast by diviners in Nigeria, Benin, Cuba, Brazil and the United States. They decorate shrines and festival dress, and are worn as jewellery as a sign of African heritage.
