Final answer:
Without a clear reference, it's difficult to ascribe the titles provided to a specific sculpture. Sculpture titles often reflect cultural background and historical periods, as seen in the artworks from various African cultures described in the references.
Step-by-step explanation:
The titles of sculptures can often be quite descriptive and lend insight into their meaning or origin. For the sculptures provided in the reference information, each has a specific title that reflects its cultural background and historical period. For example, the sculpture referred to as Figure 2.3.1 has been described as a seated figure that could represent anxiety or deep prayer from the Djenné peoples of Mali, and might be similar to the "Standing figure holding object above head" by the Dogon peoples of Mali featured in a San Diego Museum of Art exhibition. However, without a clear reference to a sculpture titled "Sculpture of a Head", "Ife", "Ile-Ife (Ife), Nigeria", or from "11th-15th c. CE", it is challenging to ascribe these titles to a specific piece in the absence of more context or a direct connection to one of the sculptures mentioned in the references. Titles like "Ancestral head of an Oba" or "Portrait Head of Queen Tiye with a Crown of Two Feathers" are more descriptive and link directly to their cultural significance.
