Art is interesting because it often gives us a window into the culture of a civilization. For example, the crucifix below is a a radical departure from the early Christian from this earlier blog. It is not uncommon for depictions of Christ to resemble the predominant race in the region of worship. In this case, Christ is shown to be of noticeably African origin. Some of the more obvious features of this crucified Christ are the stylized human form that speaks to the extent of suffering Jesus endured through the crucifixion. One of the stylistic choices is the exaggerated rib cages that communicate his pain and deprived physical state.
Another artifact testament to the the cross cultural contact that Africa had with Christian Europe is Sierra Leon pieces such as the Sapi Portuguese Hunting Horn. Made from almost the entirety of an elephant tusk, which is a very precious resource not only to the natives and even more so in trade as an export to Europe, the hunting horn intricately includes scenes of European hunts in Africa. 
Below is an image of the Christian cross on the horn indicating that this piece may have been for some European aristocrat. Ivory exports were not an uncommon request among the European aristocracy.
