Tradition described: Yorùbá / Ìṣẹ̀ṣe
What is ìyẹ̀rọ̀sùn?
Ìyẹ̀rọ̀sùn is the fine wood powder spread on the divining tray. Bascom identifies it as the dust produced by termites boring into the wood of the ìrọ̀sùn tree (a camwood, Baphia nitida). The diviner sprinkles it over the tray and, with a finger, draws in it the single and double marks that the ikin produce.
Its uses in the tradition go beyond the tray — it is used in the preparation of remedies prescribed by the verses — but those uses are the practitioner's, and are not described here.
