Final answer:
The Itombwa figures from the Kingdom of Kuba were carved from hardwood. The medium of the Itombwa figure is not bronze, marble, or clay, aligning with the cultural craftsmanship practices of the Kuba involving woodcarving and organic materials.
Step-by-step explanation:
The Itombwa figures from the Kingdom of Kuba in the Democratic Republic of the Congo (DRC) dating from 1625-1900 CE are known for their intricate craftsmanship and cultural significance. According to the information provided, these figures, particularly the ndops which are images of royal figures, were carved from hardwood, covered with palm oil, and varied in dimensions. The figures were meticulously crafted using tools such as a small ax and knives to accurately represent the actual features of the kings they depicted.
Using this context, it is clear that the medium of the Itombwa figure is not Brussels and wood fibers, bronze, marble, or clay. Instead, the medium used for the Kuba figures is hardwood, primarily because of the detailed way the figures were carved and finished.
There is also mention of other Kuba artworks such as ornate wooden boxes and drums, as well as masks made from various materials. Although these pieces are distinct in their function and style, they highlight the Kuba's mastery in wood carving and utilization of organic materials.
