An artwork that is particularly associated with the Maranao people because of their mastery of the craft, the Okir detail can also be found in Sama Dilaut boats and neighboring Moro Cultural Communities such as the Maguindanao, Iranun, Tausug, Yakan.
These geometric and flowing plant-based designs and folk motifs are commonly found in Moro and Lumad Tribes in Mindanao and some parts of Sabbah.
Historically, the earliest recorded okir design dates back the 6th Century C.E It is a pattern usually rendered on wood, silver and sometimes on wall paintings
You can see this in Maranao artifacts, decorations, and in the Maranao royalty house.
