Osa

Osa falls when nine of the sixteen Diloggun cowries land mouth up. Like most of the sixteen parent signs, its name carries across directly to the corresponding figure in Ifa divination, part of the shared Yoruba vocabulary that both oracles preserved through the upheaval of the transatlantic slave trade and the long colonial suppression of African religious practice in Cuba.

The parent signs are not, on their own, a complete divinatory system; a working reading combines two throws of the sixteen shells to produce one of the two hundred fifty six compound Odu that carry the tradition's full store of proverbs, myths and prescribed remedies, with Osa serving as one half of whichever compound figure results. That combinatorial structure is what lets a relatively compact physical kit, sixteen shells, generate a divinatory literature broad enough to address the range of situations Lucumi diviners are consulted about. The compound figures and their associated teachings are the closed-practice material proper to initiated diviners and to the person receiving a reading; this entry accordingly limits itself to Osa's place among the sixteen parent signs and the combinatorial logic that governs how they are used together.

Material on the sixteen signs has usually crossed two language boundaries before an English reader meets it: from Yoruba into Cuban Spanish across generations of oral transmission, and then from Spanish into English by a translator.

Each crossing costs something. Yoruba is a tone language and the tone marks are lost almost everywhere in Spanish and English publication, so distinct words collapse into identical spellings. Names were reshaped by Spanish phonology, which is why the same sign appears under several spellings. Proverbs, which carry much of the weight in this kind of divinatory speech, are the least translatable element of any tradition, and the least likely to survive two passes.

Bascom's 1980 volume prints Yoruba text with facing translation partly so a reader can see this happening. Most other sources do not.

The practical rule for a reader is to distrust short glosses. A single English keyword attached to a sign has been through both crossings and has usually lost its provenance on the way.

Osa, the nine-mouth throw, is documented as one of the sixteen. Its proverbs and prescribed remedies are conferred within initiated practice and are not reproduced in this entry.
