Final answer:
The Odu Ifá, interpreted by Nigerian philosopher Sophie Olúwolé, is a significant representation of Yoruba traditions, while the ancient city-states like Benin, Oyo, and Ife reflect the Yoruba's political, cultural, and artistic achievements. Early Yoruba plays would likely depict these rich traditions.
Step-by-step explanation:
The first important play that depicts the traditions of the Yoruba is thought to weave together the intricacies of Yoruba philosophy, history, and culture. Notable contributions in understanding the Yoruba traditions in the realm of philosophy and history have come from the Nigerian philosopher Sophie Olúwolé, who studied Yoruba philosophy and compared it with Western philosophical traditions. Through her work, the oral tradition of the Odu Ifá is recognized as a sophisticated system of ideas that parallels the philosophical endeavors of other ancient civilizations.
The kingdom of Benin and the city-states like Oyo and Ife, dating back to the 12th and 14th centuries respectively, reflect the developed political systems and the arts, highlighting the role of the Oni, the system of governance, and the importance of trade for the Yoruba people. Artifacts such as bronze sculptures and plaques were created to immortalize these traditions, with techniques like the lost wax method reflecting the high level of artistic achievement of Yoruba artisans. The political structures of these city-states, along with their cultural and philosophical advancements, provide a backdrop to understanding the Yoruba's extensive cultural heritage, including the performance arts, which may have been depicted in early Yoruba plays.
