We have some similar in my country. But this time the runes are replaced with cowerie shells which the juju priest (ifa,dibia, etc), can only cast.

The difference in this is that the outcome of the coweries cast can only be determined by these priests who interpret the outcome of the divination based on the cowerie layout and some other mysterious knowledge only privy to the initiated.

Interesting to see a similarity in another continent. Interesting article 👍
