Rowland Ola Abíọ́dún: In his hometown Yorubaland, there were many traditional storytellers, and Abíọ́dún was immersed in the Yoruba myths of creation and transformation.

His early exposure to traditional education in Yoruba art and culture fostered the direction of his lifelong research.  Immersion in Yoruba language, artistic concepts, and belief systems enabled Abíọ́dún to engage the philosophical notions at the heart of the Yoruba worldview.  His thorough dedication to the study of African art is encapsulated in his written works, which convey his research in a format accessible to both insiders and outsiders to the field.  Abíọ́dún aims through all of these works to directly engage his art subjects without inadvertently silencing or leaving out altogether, the voices of their creators and users.
