Final answer:
The title of the Benin artwork in question cannot be accurately determined with the provided context. While 'Ancestral head of an Oba' might be a guess based on the context, further information or a visual reference would be necessary to confirm the correct title.
Step-by-step explanation:
The title of the artwork referred to in the question is not provided in the provided information. However, based on the context given, it seems to be an artwork associated with the Benin Kingdom and the Oba, the ruler of the Benin Kingdom. If it is the ancestral head mentioned, the title could possibly be 'Ancestral head of an Oba.' Benin art includes a variety of artworks such as bronze plaques, ivory carvings, and sculptures, all created under the patronage of the Oba. The lost-wax method was a significant technique used in their creation, particularly for the bronze works, depicting the dynasty and royal lineage of the Oba.
Unfortunately, the correct title cannot be definitively determined without further context or additional information regarding the specific artwork. To identify the artwork's title correctly, an image or description of the artwork in question would be necessary. Given the historically rich tradition of Benin art, the title might reference the ruler, an event, or a characteristic aspect of the artwork's purpose or creation.
