How a Diloggun Throw Is Read

Diloggun divination casts sixteen cowrie shells, each filed or worn down on its back so that it can land either mouth up or mouth down. The number of open mouths, from zero to sixteen, names the parent sign for that throw; Okana is what results when only one shell lands open. The system reached Cuba with enslaved Yoruba people from what is now southwestern Nigeria and Benin, and cowrie shells themselves had already circulated across West Africa for centuries as currency before they were repurposed as a divining medium, a history documented by William Bascom among others.

In Cuba the practice took root inside the Regla de Ocha, commonly called Santeria, where it became the oracle proper to initiated priests and priestesses of the orishas rather than to the babalawos who read Ifa with a divining chain or palm nuts. A single reading session normally casts a parent sign twice in succession to produce one of the two hundred fifty six compound Odu that the tradition actually interprets; the sixteen parent signs described in this set are the building blocks of that larger corpus, not readings in themselves. Okana, as the first and statistically most common configuration, opens the numbered sequence used across Lucumi manuals and oral teaching alike. What a diviner says when Okana falls, the proverbs attached to it and the remedies it calls for, belongs to initiated readers and to the person who receives the reading, and is not set out on a reference page.
