Final answer:
The artwork combining Kongo cultural symbols with Christian representation of Christ is titled 'Kongo Crucifix'.
Step-by-step explanation:
The title of the artwork that combines the Kongo custom of using scepters and staffs as emblems of power with the representation of Christ as an African is known as Kongo Crucifix. This artifact reflects the historical encounter between the culture of the Kongo Kingdom and the Christian iconography introduced by Portuguese missionaries. Furthermore, artworks such as this emphasized the melding of local cultural symbols with the Christian faith, a practice that was not uncommon in regions where Christianity was being introduced or merged with existing beliefs.
