Understanding the Odù System
The Binary Lines
Each Odù is formed from marks made on the Ifá divination tray (Ọ̀pọ́n Ifá) using the sacred palm nuts (Ikin) or divining chain (Ọ̀pẹ̀lẹ̀). Each mark is either a single line (I) or a double line (II). Four marks form one "leg" — giving 16 possible leg patterns.
16 Become 256
A full casting produces two four-line legs — a right leg and a left leg. When both legs are identical, the result is one of the 16 senior Odù Méjì. When the legs differ, the combination produces one of the 240 Omo Odù — each read as its own distinct figure with unique guidance.
Reading an Odù
A trained Babaláwo or Ìyánífá recites the Ẹsẹ Ifá (verses) associated with the cast Odù, drawing on years of memorised oral literature to offer guidance specific to the situation. Our encyclopedia offers a simplified, educational introduction to this vast tradition.
